2.20_2 2009-05-17 (2.21 candidate)

  - Applied a patch to Template::Test from Andrew Ford to make it skip
    properly.
    http://lists.tt2.org/pipermail/templates/2009-March/010678.html

  - Changed the ttree -v/--verbose option so be less verbose and only
    report on things that have changed.  To make it more verbose (like
    previous versions), add a second -v/--verbose flag, e.g.

      $ ttree -v -v

  - Also added the --summary option to tree to print a summary of what it
    did, and the --color/--colour option to make it print its verbose
    messages in colour (on ANSI terminals).

  - Applied a ttree patch from Lyle Brooks to allow ttree to accept a
    directory name as a command line argument.

  - Added the define_view() and define_views() method to Template::Context

2.20_1 2009-04-07 (2.21 candidate)

  - Deleted all the old HTML documentation (now available separately from
    http://tt2.org/download/index.html#html_docs), examples, libraries and
    other cruft that was way out of date and badly unloved.

  - Tweaked Template::Parser to work better with the ANYCASE option.  It
    now knows that anything following a dotop cannot be a keyword so that
    you can write data.last without the 'last' bit being interpreted as the
    LAST keyword.  Thanks to Sean McAfee for the post that inspired it.
    http://lists.tt2.org/pipermail/templates/2008-September/010462.html

  - Fixed a broken test for Apache::Util in the html_entity filter.  Added
    the use_html_entities() and use_apache_util() class methods to
    Template::Filters to allow end-user selection of one or the other.
    http://rt.cpan.org/Public/Bug/Display.html?id=40870
    http://template-toolkit.org/svnweb/Template2/revision/?rev=1177

  - Tweaked Template::Context to recognise Badger::Exception objects and
    convert them to Template::Exception objects.  This is a temporary
    measure to keep things working during the transition to Badger-based
    modules.

  - Added the STRICT option which will cause the stash to throw an
    exception on encountering an undefined value.  Thanks to Ben Tilly
    for the prod.

  - Applied a patch to Template::Iterator from Jonathon Padfield to make
    get_all() do the right thing if get_first() hasn't been called.

  - Applied a patch to Template::Stash::Context from Ben Tilly to make
    it easier to subclass.

  - Applied a patch from Robin Berjon to add the xml filter.

2.20 2008-08-13

  - Updated all the documentation.

  - Restored the GIF images that got mangled in the switch from CVS to

    http://rt.cpan.org/Ticket/Display.html?id=25573

  - Applied a patch to Template::Directives from Ben Morrow to fix the
    SWITCH/CASE directive when matching strings containing regex metacharacters.
    http://rt.cpan.org/Ticket/Display.html?id=24183

  - Applied a patch to Template::Parser from Koichi Taniguchi to make it
    treat TAGS with case sensitivity.
    http://rt.cpan.org/Ticket/Display.html?id=19975

  - Changed html_entity_filter_factory() in Template::Filters to only look for
    Apache::Utils and HTML::Entities once.
    http://rt.cpan.org/Ticket/Display.html?id=19837

  [Template::Stash]
  - Applied a patch to Template::Stash from Jess Robinson which allows you
    to call a list method on a single object and have it automatically
    upgraded to a single item list.  Changed the XS Stash to do the same.
    http://lists.tt2.org/pipermail/templates/2006-November/009115.html

  - Fixed a minor bug in the XS Stash which prevented it from updating
    hash entries with empty, but defined keys.  Thanks to Yitzchak
    Scott-Thoennes for reporting the problem.
    http://lists.tt2.org/pipermail/templates/2007-November/009819.html

  - Applied a patch from Alexandr Ciornii  to make the XS Stash compile
    cleanly under VC++ 6.0 and with Sun's C compiler.
    http://rt.cpan.org/Ticket/Display.html?id=20291

  [Template::Provider]
  - Fixed a minor bug in the Template::Provider code added in 2.19 that
    caused errors in templates to only be reported once.  Subsequent
    fetches incorrectly returned 'not found' instead of repeating the
    error.

  - Made Template::Provider use File::Spec->catfile instead of using '/'
    and letting Perl worry about Doing The Right Thing.
    http://rt.cpan.org/Ticket/Display.html?id=34489

  - Applied patch from Lyle Brooks to add binmode to the _template_content()
    method in Template::Provider.
    http://rt.cpan.org/Ticket/Display.html?id=38075

    a bug in Strawberry Perl on Win32.
    http://rt.cpan.org/Ticket/Display.html?id=34578

  [Template::VMethods]
  - Applied a patch from Paul "LeoNerd" Evans to make the list.slice vmethod
    work properly with negative indices.
    http://lists.tt2.org/pipermail/templates/2008-March/010105.html

  [Plugins]
  - Added the Math plugin and related files to the MANIFEST so they
    actually get shipped out as part of the distribution.  D'Oh!
    http://rt.cpan.org/Ticket/Display.html?id=27375

  - Added the Scalar plugin which adds the .scalar vmethod for calling
    object methods and subroutines in scalar context.

  - Added Template::Plugin::Assert which allows you to assert that values
    are defined.

  - Changed Template::Plugin::Filter to weaken the $self reference to avoid
    circular references and memory leaks.  Thanks to Masahiro Honma for
    reporting the problem and suggesting the fix.

  - Applied patch from Ronald J Kimball to make Template::Plugin::Date accept
    dates with the year coming first.
    http://lists.tt2.org/pipermail/templates/2007-July/009540.html

  - Added C<1;> to the end of a few plugin modules that were missing it.

  [ttree]
  - Changed the --accept option in ttree to match against the full file
    path (relative to --src dir) rather than just the file name.  This
    makes it behave the same way as the --ignore option.

  - Applied patch from Lyle Brooks to add binmode to the process()
    call in ttree.
    http://rt.cpan.org/Ticket/Display.html?id=38076

  - Added a patch from Nigel Metheringham also to set binmode in ttree
    but via a configuration option.
    https://rt.cpan.org/Ticket/Display.html?id=30760

  - Applied a patch from Éric Cholet to add the --encoding option to ttree.
    http://lists.tt2.org/pipermail/templates/2008-August/010369.html

2.19 2007-04-27

  - Applied a patch to t/fileline.t from Steffen Müller which fixes the
    problems running on Win32 with backslashes in paths.

    https://rt.cpan.org/Ticket/Display.html?id=20488

  - Applied a patch to the XS Stash from Randy Kobes which fixes some other
    Win32 problems.

    http://lists.tt2.org/pipermail/templates/2007-February/009247.html

  - Applied another patch to the XS Stash from Steve Peters which fixes
    a problem with tied hashes under more recent version of Perl.

    http://lists.tt2.org/pipermail/templates/2007-January/009181.html

  - Fixed a problem in the Perl Stash when using objects that have
    overloaded comparison operators.  Thanks to Randal Schwartz, Tatsuhiko
    Miyagawa and Daisuke Maki for their contributions.

    http://lists.tt2.org/pipermail/templates/2007-March/009265.html

  - Applied a patch from Bill Moseley to Template::Provider which adds
    negative caching and moves some functionality into separate methods
    to make subclassing easier.  Also added the STAT_TTL configuration
    parameter.

    http://lists.tt2.org/pipermail/templates/2007-January/009183.html

  - Added the url filter as a less aggressive form of the uri filter.
    Whereas the uri filter now (from v2.16 onwards) encodes all the
    reserved characters (@, :, /, etc.) as per RFC2396, the url filter
    leaves them intact and thus behaves just like the uri filter used
    to.

    http://lists.tt2.org/pipermail/templates/2007-March/009277.html

2.18a 2007-02-09

  - Applied a patch from Steve Peters to the Stash.xs to allow it to
    compile with bleadperl 5.9.x

    https://rt.cpan.org/Public/Bug/Display.html?id=22506

2.18 2007-02-09

  - Merged in Adam's changes in 2.16 and 2.17 back into the developer CVS
    repository and added his name to the credits.

  - Changed the parser grammar to accept expressions as arguments to a
    subroutine, method or virtual method call.  I'm embarrassed to admit
    that it was a one line change that could (and should) have been made
    long ago, if only I had realised just how trivial it was.  Anyway,
    you can now write nested expressions like this:

       [% add(a+5, b < 10 ? c : d + e*5) %]

  - Put the t/fileline.t test back in as this was fixed in 2.15a

  - Added the Template::Toolkit documentation-only module.

2.17 2007-02-08

    Another interim release from Adam Kennedy.

  - Change in Makefile.PL to force an upgrade to File::HomeDir 0.64 on darwin.
    This is due to problems caused by changes made to Perl on the new Intel
    versions of Mac OS X.

  - skip_all filelines.t on darwin

2.16 2007-01-23

    Interim release from Adam Kennedy.

  - Skip fileline.t on Win32, as it has some hard-coded path seperator
    assumptions. This will be fixed more comprehensively later.

  - Handle spurious errors in Makefile.PL when a dev version of
    ExtUtils::MakeMaker is installed.

  - Don't say "nmake" on Win32 when $Config{make} is 'dmake'.
    This corrects the message on Strawberry Perl.

 - Not released  ## DEVELOPER RELEASE ##

  - Fixed a bug in Template::Parser which caused it to get confused about
    block names if it encountered a syntax error inside a BLOCK.  Thanks
    to Bill Moseley for reporting the problem.

    http://lists.tt2.org/pipermail/templates/2006-July/008815.html

  - Fixed a minor buglet in Template::Provider which came to light while
    investigating the above problem. If a previously cached template is changed
    on disk and then fails to compile, the provider now invalidates the cache
    entry immediately. Without this fix, the provider would report the error
    once, then reuse the cached good version of the template until $STAT_TTL
    ticked over when it would try to load and compile the disk version again.
    The problem was that error messages were only reported once every $STAT_TTL
    second(s) and any requests for the same template in the interim time would
    mysteriously work. This way errors get reported consistently and immediately
    and no-one has to waste an afternoon trying to figure out where the errors
    went!

2.15b 2006-05-30  ## DEVELOPER RELEASE ##

  - Changed the uri filter to escape all reserved characters as per
    URI::Escape and RFC2396.  This now includes &, @, /, ;, :, =, +, ?
    and $ which were previously not escaped.  Thanks to islue@cpan.org
    for reporting the problem.

    http://rt.cpan.org/Ticket/Display.html?id=19593

  - Also changed the uri filter to encode all wide characters as the
    equivalent UTF escapes.  Thanks to Jonathan Rockway for reporting
    the problem.

    http://rt.cpan.org/Ticket/Display.html?id=19354

  - Fixed the redirect filter to not support relative paths.  Thanks to
    Paul Seamons for spotting the problem and providing a solution.

  - Moved all the virtual methods out of Template::Stash and into
    a new Template::VMethods module.

  - Fixed the version number of Template::Stash which had rolled over
    to 2.102 making it appear to predate the 2.86 stash in TT v2.14.
    Thanks to Randal Schwartz for reporting the problem.  Changed all
    version numbers in other modules to be a hard-coded numbers instead
    of grokking it automagically from the CVS revision.

  - Changed the _recover() method of Template::Service to check if the
    error thrown is a Template::Exception object rather than just a
    reference.  Thanks to David Wheeler for reporting the problem.

    http://rt.cpan.org/Ticket/Display.html?id=17630

  - Fixed the some tests in stash.t and stash-xs.t which were failing
    under Perl 5.6.2 due to a slightly different error message being
    generated.  Thanks to Anton Berezin for reporting the problem.

  - Fixed a bug in the Template::Provider _load() method to check that
    $data is a hash ref before trying to mess with its innards.  Thanks
    to barbie@cpan.org for reporting the problem.

    http://rt.cpan.org/Ticket/Display.html?id=18653

2.15a 2006-05-29  ## DEVELOPER RELEASE ##

  - Removed the latex filter from Template::Filters and related config
    variables from Template::Config

  - Changed the t/fileline.t test to remove the line number from what Perl
    reports as "(eval $line)".  It appears to get the $line wrong on
    FreeBSD, although the correct line number is reported following that
    so the tests still do the right thing.  Thanks to Anton Berezin for
    reporting the problem.

  - Changed the t/compile3.t test to do something similar.

2.15 2006-05-26

  [Chomping Options]
  - Added the CHOMP_GREEDY option and '~' chomping flag.  Changed
    CHOMP_COLLAPSE to greedily chomp all whitespace (including multiple
    newlines) and replace it with a single space.  Previously it only
    chomped one line.  Renamed the CHOMP_ALL option to CHOMP_ONE which
    makes more sense.  CHOMP_ALL is still provided as an alias for
    CHOMP_ONE for backwards compatibility.  Thanks to Paul Seamons for
    doing all the hard work on this.

    http://lists.tt2.org/pipermail/templates/2006-February/thread.html#8354

  - Added code to the replace text virtual method to use a faster and
    simpler implementation if the replacement text doesn't contain any
    back references.  Thanks to Josh Rosenbaum for all his efforts on
    this.

    http://lists.tt2.org/pipermail/templates/2006-February/008344.html

  [Stash]
  - Changed various tests for private/hidden variables (starting '_'
    or '.') to use a regex defined in the $PRIVATE package variable in
    Template::Stash.  This can be redefined or undefined.  Note that
    the XS Stash only looks to see if $PRIVATE is defined or not, and
    currently hard-codes the regex.

  [Plugins]
  - Changed the Image plugin tag() method to call the name() method
    instead of accessing the name directly, making it easier for
    subclasses to provide an alternate name.  Thanks to Cees Hek for
    his patch.

    http://lists.tt2.org/pipermail/templates/2006-February/008423.html

  - Change the AUTOLOAD regex in the Table plugin to be more robust.

    http://lists.tt2.org/pipermail/templates/2006-May/008602.html

  [Documentation]
  - Added the Template::Toolkit documentation pointing people to
    the right place.

  - Updated the Template::Stash::XS documentation to remove the
    "experimental" description and tidy things up a bit.

2.14a 2006-02-02  ## DEVELOPER RELEASE ##

  [Stash]
  - Activated a patch in Template::Stash from Stephen Howard which adds
    code for the full set of fallbacks for dot ops called against
    objects which don't implement the specific method.  For example
    [% hashobj.vmethod %] [% listobj.2 %] and [% listobj.vmethod %] now
    all work with the Perl Template::Stash.  Added code to the XS Stash
    to do the same and updated tests.

    http://template-toolkit.org/pipermail/templates/2003-December/005417.html

  - Added full support for tied hashes and tied lists in the XS Stash.
    Added some further tests to make sure it's all working as expected.

    http://lists.tt2.org/pipermail/templates/2006-January/008266.html

  - Applied path from Slaven Rezic to Template::Stash::XS to check
    return code in tt_fetch_item() in a way which plays nicely with tied
    hashes.

    http://rt.cpan.org/Ticket/Display.html?id=7830

  - Changed Template::Stash and Template::Stash::XS to evaluate list
    vmethods in lvalues.

    http://lists.tt2.org/pipermail/templates/2006-January/008198.html

  - Changed Template::Stash to be a little more strict about what it
    considers a failed method call.  This allows exception thrown within
    called methods to be propagated correctly rather than being ignored
    as undefined method.  Thanks to Dave Howorth, Tom Insam and Stig
    Brautaset for reporting the problem and providing fixes.

    http://lists.tt2.org/pipermail/templates/2005-April/007375.html
    http://lists.tt2.org/pipermail/templates/2006-February/008367.html

  - Removed redundant performance profiling code from
    Template::Stash::XS.  Must check with Doug that this is OK and he's
    not still using it...

  [Virtual Methods]
  - Added the scalar.remove, scalar.substr, hash.delete, hash.items,
    hash.pairs, list.import and list.hash virtual methods.

  - Changed the scalar.replace method to work properly with back
    references ($1, $2, etc) by incorporating ideas, code and tests from
    Nik Clayton, Paul Seamon, Sergey Martynoff, Josh Rosenbaum and
    others.

    http://lists.tt2.org/pipermail/templates/2006-February/008306.html
    http://lists.tt2.org/pipermail/templates/2006-February/008326.html

  - Changed list.push and list.unshift to accept multiple arguments,
    thanks to Bill Moseley.

    http://lists.tt2.org/pipermail/templates/2006-January/008294.html

  - Fixed the split scalar virtual method which wasn't accepting the
    second argument (limit) correctly.  Thanks to Josh Rosenbaum for
    pointing out the problem.

    http://lists.tt2.org/pipermail/templates/2005-October/007982.html

  - Documented the fact that hash.list is going to change in the future,
    recommending people switch to hash.pairs.

    http://lists.tt2.org/pipermail/templates/2006-January/008256.html
    http://lists.tt2.org/pipermail/templates/2006-February/008312.html

  - Added the global option to the 'match' scalar virtual method.

  - Changed $element to $component in Template::Context to fix callers
    bug, thanks to Andy Maas who identified the problem and found the
    solution:

    http://lists.tt2.org/pipermail/templates/2004-December/007020.html

  - Changed the sort and nsort list virtual methods to always return
    references to lists, avoiding any ambiguity in return results.

  - Changed the hash.defined method to do the same thing as
    scalar.defined when called without arguments.  Added list.defined to
    do the same thing as hash.defined.

    http://rt.cpan.org/Ticket/Display.html?id=9094

  - Moved all the tests into t/vmethods/*

  [Plugins]
  - Added the $Template::Plugins::PLUGIN_BASE package variable to define
    the default 'Template::Plugin' value for the PLUGIN_BASE option.  By
    clearing this value before calling the Template new() constructor,
    you can avoid having Template::Plugin added to the PLUGIN_BASE by
    default.  Also changed PLUGINS search to look for lower case plugin
    name as well as case-specific name.  Thanks yet again Josh for
    addressing this issue.

    http://lists.tt2.org/pipermail/templates/2006-January/008225.html

  - Applied a single character patch from Lubomir Host which fixes the
    user attribute in Template::Plugin::File.

  - Added the Math Plugin to MANIFEST.

  - Changed the URL plugin to ignore parameters that are unset (e.g.
    defined but zero length)

  - Applied two patches to the Image plugin from Bill Moseley to escape
    attributes in the tag() method and to provide the 'file' options.
    Also adds proper documentation for the 'root' option.

    http://lists.tt2.org/pipermail/templates/2005-November/008086.html
    http://lists.tt2.org/pipermail/templates/2005-December/008189.html

  - Added the $JOINT package variable to Template::Plugin::URL to
    provide a work-around for the URL plugin which incorrectly (as
    we now know) encodes '&' as '&amp;'

    http://rt.cpan.org//Ticket/Display.html?id=11551
    http://lists.tt2.org/pipermail/templates/2005-December/008158.html

  - Added substr() method to the String plugin, as suggested here:

    http://rt.cpan.org/Ticket/Display.html?id=2619

  - Moved all XML plugins and related tests into a separate Template-XML
    distribution.

  - Moved DBI plugin and tests into Template-DBI distribution.

  - Moved GD plugins and tests into Template-GD distribution.

  [Filters]
  - Applied a patch to the truncate() filter from "Ashley" which
    adds a second argument.

    http://lists.tt2.org/pipermail/templates/2005-December/008145.html

  - Fixed a bug in the same truncate() filter to stop it from truncating
    strings that are exactly as long as the limit (change '<' to '<='),
    thanks to Nicholas at oxhoej.dk.

    http://rt.cpan.org/Ticket/Display.html?id=8911

  - Added "use locale" to Template::Filters to enable locale-specific
    filters.

    http://rt.cpan.org/Ticket/Display.html?id=9094
    http://rt.cpan.org/Ticket/Display.html?id=5695

  - Updated documentation to reflect the fact that the html filter also
    escapes " as &quot; Thanks to Geoff Richards for reporting it.

  - Moved Latex filters into Template-Latex distribution.

  [ttree]
  - Applied patch from Yuri Pimenov to prevent ttree from raising a
    warning when the --depend_debug option is used.

    http://lists.tt2.org/pipermail/templates/2005-May/007400.html

  - Applied a patch to ttree from Slaven Rezic which fixes the arguments
    passed to mkpath.

    http://rt.cpan.org//Ticket/Display.html?id=14216

  - Applied a patch to ttree from Mike Schilli to prevent it from going
    into an infinite loop on encountering a directory called "0"

    https://rt.cpan.org/Ticket/Display.html?id=14905

  - Fixed configuration section to not prompt "Do you want me to create
    a sample .ttreerc file?" if the -h/--help options are specified,
    thanks to Slaven Rezic for reporting the problem.

    http://rt.cpan.org/Ticket/Display.html?id=4180

  - added AppConfig EXPAND => EXPAND_ALL option to perl5lib,
    template_plugin_base, template_compile_dir and depend_file
    configuration options to allow them to contain ~ to indicate
    the user's home directory, or $WHATEVER for environment variables,
    as per the other path-specific options like src, lib, etc.

  [Miscellaneous]
  - Added code to Makefile.PL to detect $ENV{PERL_MM_USE_DEFAULT} to
    accept all defaults.  Thanks to KANE.

    http://rt.cpan.org/Ticket/Display.html?id=14613

  - Removed vStrings from Template::Document.  Thanks to Dave Cross for
    reporting the problem.

    http://lists.tt2.org/pipermail/templates/2005-April/007357.html

  - Applied a patch from Barrie Slaymaker which corrects a bug in the
    Template::Parser line counting when using chomp flags.

    http://lists.tt2.org/pipermail/templates/2005-December/008157.html

  - Applied a patch from Jess Robinson to move the Template::Provider
    check for file freshness into a separate method, in order to
    play nicely with his Template::Provider::DBI module.

    http://lists.tt2.org/pipermail/templates/2005-December/008143.html

  - Fixed the regex matching relative paths in Template::Provider, thanks
    to Josh Rosenbaum

    http://lists.tt2.org/pipermail/templates/2005-January/007141.html

  - Applied a patch to Template::Provider to prevent a misleading error
    message, thanks to Slaven Rezic.

    http://rt.cpan.org/Ticket/Display.html?id=5327

  - Added an eval wrapper around mkpath() in Template::Provider to handle
    errors more nicely.

  - Numerous documentation fixes.

2.14 2004-10-04

  - Applied patch from Harald Joerg to prevent ttree from spewing warnings
    when copying files.
    http://template-toolkit.org/pipermail/templates/2004-March/005897.html

  - Applied a patch from Paul Orrock to fix a couple of missing errors in
    ttree.
    http://template-toolkit.org/pipermail/templates/2004-September/006605.html

  - Commented out line 797 of Template::Directive.pm which serves no
    purpose and generates a warning.

  - Applied a patch from Mark Fowler to add support for Unicode to TT.
    http://template-toolkit.org/pipermail/templates/2004-June/006270.html

  - Changed the fourth argument to process() to accept named IO layers for
    binmode, e.g. process($in, $vars, $out, binmode => ':utf8');

  - Added full range of command line options to tpage.
    http://template-toolkit.org/pipermail/templates/2004-September/006545.html

  - Applied patches from Tosh Cooey, Simon Wilcox and Kenny Gatdula to fix
    XML::Simple to allow direct access to XMLin() and XMLout() methods. See
    http://template-toolkit.org/pipermail/templates/2004-September/006620.html

  - Fixed a bug in the 'callers' list maintained by a template component
    which was failing to remove callers from the list after processing.
    http://template-toolkit.org/pipermail/templates/2004-April/006070.html

  - Applied a doc patch from Dave Cash documenting caller and callers.
    http://template-toolkit.org/pipermail/templates/2004-March/005960.html

2.13 2004-01-30

  - Applied patch from Dave Cash to add 'caller' and 'callers' to
    'component', see
    http://lists.tt2.org/pipermail/templates/2004-January/005581.html

  - Applied patch from Dylan William Hardison to ttree which prevents
    dependencies from interfering with files that are copied.  See
    http://lists.tt2.org/pipermail/templates/2003-December/005458.html

2.12a 2004-01-13  ## DEVELOPER RELEASE ##

  - Fixed the bug in test 25 of t/date.t, hopefully for good this time,
    thanks to the efforts of Steve Peters.  See:
    http://template-toolkit.org/pipermail/templates/2004-January/005560.html

  - Added the FILE_INFO option to Template::Parser.  Enabled by default,
    this can be set to 0 to prevent the parser from adding file and line
    info to the generated Perl file.  Don't ask me why - Autrijus wanted
    it (which probably means he's up to something twisted again :-).  See:
    http://template-toolkit.org/pipermail/templates/2004-January/005552.html

2.12 2004-01-12

  - Added the module_version() method to Template::Base to report the
    version number of a module.  Added some tests to t/base.t.

  - Added the --template_module option to ttree, to allow the user to
    specify a template processing module other than the default 'Template'
    to be used.  Also changed various print statements to send all
    verbose output to stdout, whereas previously it was split across stdout
    and stderr.

2.11b 2004-01-07  ## DEVELOPER RELEASE ##

  - Applied patch from Myk Melez to ensure the 'component' variable
    remains correctly set to the current templates.  See
    http://template-toolkit.org/pipermail/templates/2004-January/005483.html

2.11a 2004-01-06  ## DEVELOPER RELEASE ##

  - Fixed bug in t/date.t and corrected version number of
    Template::Grammar.

2.11 2004-01-06

  - Bumped version number and updated documentation for release.

2.10b 2003-12-02  ## DEVELOPER RELEASE ##

  - Changed the Template::Document process() method to pass itself
    to the context visit() method when it calls it.  Similarly, changed
    the context visit() method to expect it.  This is useful when
    subclassing the context but shouldn't have any other effect.

  - Modified parser to add the file name and line number of the source
    template to generated Perl code.  This provides useful information
    when warnings and errors are generated by Perl at runtime.  Added
    the t/fileline.t script to test it.

2.10a 2003-10-09  ## DEVELOPER RELEASE ##

  - Applied two patches from Axel Gerstmair to fix bugs in Makefile.PL
    and t/date.t.  See.
    http://lists.tt2.org/pipermail/templates/2003-April/004553.html
    http://lists.tt2.org/pipermail/templates/2003-May/004572.html

  - Applied patch from Jim Cromie to t/autoform.t to skip tests on all
    versions of Perl from 5.8.0 onwards.

  - Changed $OUTPUT in Template::Directive to be a package variable,
    allowing it to be re-defined to permit a flushed output hack.
    http://lists.tt2.org/pipermail/templates/2003-October/005136.html

  - Applied a patch from Darren to the 'item' hash vmethod to protect
    against accessing private variables (prefixed '.' or '_')
    http://lists.tt2.org/pipermail/templates/2003-June/004761.html

  - Applied a patch from Ivan Adzhubey to template/splash/frame.
    http://lists.tt2.org/pipermail/templates/2003-August/004953.html

  - Applied a patch from Bryce Harrington to add the absolute and
    relative options to ttree.  Also applied a patch from Mark Anderson
    to add the 'template_debug'.  Removed the old debug option which was
    as good as useless.
    http://lists.tt2.org/pipermail/templates/2003-October/005110.html
    http://lists.tt2.org/pipermail/templates/2003-October/005126.html

  - Applied another patch from Mark to push files named on the command
    line through the process_file() sub to ensure that various options
    like accept checking, pemission preserving and copy processing (but
    not modification time) are applied.
    http://lists.tt2.org/pipermail/templates/2003-October/005132.html

  - Applied a variation of yet another ttree patch from Mark to add the
    'suffix' option for changing the suffix of output files created.
    http://lists.tt2.org/pipermail/templates/2003-October/005121.html

  - Applied a variation of a patch from Dylan William Hardison which
    adds the 'depend' and 'depend_file' options to ttree.
    http://lists.tt2.org/pipermail/templates/2003-July/004783.html
    http://lists.tt2.org/pipermail/templates/2003-October/005147.html

2.10 2003-07-24

  - Merged in Darren's branch to add the define_vmethod() methods to
    Template::Context and Template::Stash.

  - Applied patch from Axel Gerstmair for minor fixes to Makefile.PL,
    t/gd.t and t/date.t.
    http://template-toolkit.org/pipermail/templates/2003-April/004545.html

  - Added undefined() method to the Stash which get() calls if a variable
    value is undefined.  Currently just returns '' to implement existing
    behaviour, but it provides a method hook for subclasses to redefine.

  - Fixed a minor bug which prevented the Stash from being subclassable
    by removing references to __PACKAGE__

2.09c 2003-04-29  ## DEVELOPER RELEASE ##

  - applied patch from Ivan Kurmanov to XPath plugin to add handling for
    comments.

  - modified grammar to allow 'IN' as an alternate for '=' in FOREACH
    directives, thus allowing [% FOREACH item IN [ foo, bar, baz ] %]
    http://template-toolkit.org/pipermail/templates/2003-April/004519.html

  - changed test for PROCESS option in Template::Service init from 'exists'
    to 'defined' so that PROCESS set to undef Does The Right Thing.
    http://template-toolkit.org/pipermail/templates/2003-April/004536.html

  - changed Template::process() method to accept a hash reference or list
    of output options following any filename.  This can now be used to
    explicitly set binary mode (or not) for the output of a file.  Also
    changed Template::_output() method to expect a reference to text rather
    than a duplicated text string (for efficiency) and also the new hash
    reference of options.  Also changed the redirect and stdout filters
    accordingly.

  - disabled the mandatory binmode setting on all files created under
    MSWin32.  See previous item for details on how binmode can now be
    set explicitly, or link below for description of problem.
    http://template-toolkit.org/pipermail/templates/2003-April/004499.html

  - applied patch from Axel Gerstmair to Makefile.PL to add TT_EXTRAS item.
    http://template-toolkit.org/pipermail/templates/2003-April/004543.html

2.09b 2003-04-24  ## DEVELOPER RELEASE ##

  - fixed bug introduced in 2.08e which caused some exception handling to
    fail under Perl 5.6.1 and earlier.
    http://template-toolkit.org/pipermail/templates/2003-April/004502.html

  - applied patch from Tatsuhiko Miyagawa to gd.t test to change size test
    from 6500 to 6000.

  - applied patch from Axel Gerstmair to the Image plugin.
    http://template-toolkit.org/pipermail/templates/2003-April/004496.html

2.09a 2003-04-23  ## DEVELOPER RELEASE ##

  - added WRAPPER configuration item, documentation and tests.  Also added
    'wrapper' configuration item to ttree.  See Template::Manual::Config

  - applied patch from Axel Gerstmair to fix File::Spec and File::Temp
    versions in Makefile.PL.
    http://template-toolkit.org/pipermail/templates/2003-April/004480.html

2.09 2003-04-23

  - Bumped version number for release.

2.08e 2003-03-18  ## DEVELOPER RELEASE ##

  - changed Template::Provider and Template::Context to propagate nested
    exceptions (e.g. [ file => [ parse => 'blah blah' ] ]) to allow the
    caller to accurately differentiate between parse errors and missing
    file or other errors.
    http://lists.tt2.org/pipermail/templates/2003-March/004359.html

  - applied a patch from Gervase Markham to add set_legend() to the
    various GD::Graph modules that works with a list of arguments.
    http://lists.tt2.org/pipermail/templates/2003-March/004316.html

2.08d 2003-03-18  ## DEVELOPER RELEASE ##

  - Made Template::Exception DTRT with overloading (mark)

  - Applied a patch from Jonas Liljegren to lower the chunking limit of
    the parser regex to prevent a segfault.  See
    http://lists.tt2.org/pipermail/templates/2003-February/004290.html

  - Applied Pudge's patch for the XS Stash bug.  See

2.08c 2002-11-04  ## DEVELOPER RELEASE ##

  - Applied a patch from Bradley Baetz to work around a bug in Perl when
    using an overridden die(), as CGI::Carp does, for example.

  - Added the Image plugin interfacing to the Image::Size module, based
    on examples posted to the mailing list by Darren and Mark.  See
    http://lists.tt2.org/pipermail/templates/2002-November/003876.html

2.08b 2002-11-01  ## DEVELOPER RELEASE ##

  - Applied two patches from Leon to fix bug in constant folding with
    multiple replacements (a missing 'g' on a s///)

  - Applied a patch from Tatsuhiko Miyagawa to Template::Constants to
    replace 'our' perl5.6isms.

  - Added the Template::Plugin::Procedural module for creating plugins that
    use subroutines rather than method calls.

  - Fixed a html.t test to allow numerical instead of named entities (mark)

  - Added the params() method to the CGI plugin.

  - Changed File::Temp and File::Basename to be loaded dynamically in
    Template::Document as and when needed.  Thanks to a patch from
    Bradley Baetz.

  - Added a preload() method to Template::Config to preload in advance
    all the Template::* modules typically used.  Also added call to
    preload() from Template module if $ENV{MOD_PERL} is set.

  - Applied a patch from Randal Schwartz to fix rowspan attribute in
    templates/html/cell and templates/html/row

2.08a 2002-08-14  ## DEVELOPER RELEASE ##

  - Totally re-implemented the handling of the DEBUG parameter.  Added
    DEBUG_* constants to Template::Constants which can be used to enable
    different debugging options and messages.

  - Added skip_all($reason) to Template::Test and fixed up a whole bunch
    of tests to use it.  Also made other minor fixes to the tests to run
    nicely (or bail politely) under Perl 5.8.0

  - Applied patch from Slaven Rezic to Template::Plugin::Data which
    modifies the locale loading to append various suffixes (e.g. '.UTF-8')
    in the case that the unadorned locale can't be loaded.

  - Bumped version number of File::Spec to 0.8 in Makefile.PL PREREQ_PM.
    Previous versions didn't include splitdir().  Thanks to Slaven Rezic
    for reporting the problem.

2.08 2002-07-30

  - Applied two minor patches from Leon to remove 'use warnings' from 2
    test scripts to maintain compatability with 5.005

2.07c 2002-07-22  ## DEVELOPER RELEASE ##

  - Fixed a bug in Date plugin introduced in last version which caused
    it to ignore the 'time' parameter.

  - Modified INCLUDE_PATH handling in Template::Provider to accept a
    reference to a subroutine or object implementing a paths() method
    as an element in the list.  This is then called to return a
    dynamically generated path.  Documented and tested.

  - Changed the implementation of the NAMESPACE calling code to leave
    the namespace prefix intact on the ident list which then gets
    passed to the handler's ident() method.  Modified the ident()
    method of Template::Namespace::Constants to expect and remove it.
    Constant folding now *doesn't* happen for constants that return
    a reference or undefined value.  These get compiled as regular
    runtime variable lookups.

  - Added new list virtual methods: 'unique' to cull multiple identical
    items, 'merge' to merge lists together, 'splice' which acts
    just like Perl's splice, and 'slice' which returns a slice of the
    list.  Also modified first and last virtual methods to take an
    argument indicating the number of items to return from the start or
    end of the list.  Added the 'chunk' scalar virtual method to split a
    string into chunks of a particular flushed either left or right.
    (darren, mark, abw)

  - Moved documentation for virtual methods into a separate manpage,
    Template::Manual::VMethods

  - Modifed Template::Test to allow -- name testname -- comments to
    be added to tests to give them names, reported by test harness
    (darren)

  - Merged functionality of process() and include() methods into
    process() with optional third $localize flag.  (darren)

  - Modified the OUTPUT option to accept a reference to a list (darren)

2.07b 2002-07-07  ## DEVELOPER RELEASE ##

  - Added the CONSTANTS, CONSTANTS_NAMESPACE and NAMESPACE options, the
    Template::Namespace::Constants module, documentation and t/constants.t
    test suite.  This adds support for compile-time constant folding and
    other custom namespace handlers.

2.07a 2002-07-05  ## DEVELOPER RELEASE ##

  - Changed the Perl and XS stashes to automatically promote a scalar
    to a list and apply a list virtual method (if defined) as a last
    ditch attempt.

  - Changed Template::Stash::Context virtual methods to import those
    of Template::Stash.

  - Fixed a potential race condition when using compiled templates
    by changing Template::Document::write_perl_file() to write
    to a temporary file and then rename it into place, thus preventing
    two separate processes attempting to write the same file at the
    same time.

  - Added the DEBUG and DEBUG_FORMAT options and the corresponding
    DEBUG directive.

  - Fixed bug introduced to Template::Provider in 2.06g which changed
    handling of trailing slashes on COMPILE_DIR.

  - Fixed a bug in Template::Parser to preserve any post-chomp flags
    that were otherwise ignored when an entire directive is commented
    out, e.g.

      [%# blah
        # blah
      -%]

  - Applied a patch from Harald Joerg so that ttree considers files
    with equal mtime to be "not modified".

  - Applied a patch from Keith Murphy adding the gmt flag to the Date
    plugin.

  - Applied Makefile.PL portability patch from Chris Nandor.

  - Minor documentation fixes.

2.07 2002-04-17

  - Changed example in synopsis of Template::Plugin::XML::Style to one
    based on that posted to the mailing list by Tony Bowden.

  - Fixed a single/double quoting bug in docsrc which prevented [% and %]
    being correctly displayed in the tables of contents in HTML docs.

2.06g 2002-04-15  ## DEVELOPER RELEASE ##

  - Fixed a bug in ttree which prevented it from passing the recurse option
    onto the Template object due to a name mismatch: recurse/recursion

  - Changed Template::Test to accept messages to ok().  Also added is()
    as an alias for match().

  - Fixed an oversight/bug in the XS stash where a missing aTHX_ around
    line 546 caused compilation to fail under Win32.

  - Applied a patch to Template::Provider from Alexander Schilling which
    untaints paths before calling mkpath() to prevent errors under -T.

  - Fixed Template::Parser so that the INTERPOLATE option now works with
    files > 32K, thanks to the efforts of Stephen Adkins.

2.06f 2002-03-13  ## DEVELOPER RELEASE ##

  - Fixed a bug in both the Perl and XS Stash modules which resulted in
    virtual methods being called on the base stash, e.g. [% size %]
    was treated as [% stash.size %].  The only exception that we allow
    through is 'import' so that we can [% import(another_hash) %]

  - Fixed the compilation of the XS Stash on earlier versions of Perl
    (e.g. 5.00503) and other platforms (e.g. Win32) by including the
    ppport.h file.

  - Fixed a warning about undefined values in Template::Plugin::Format
    raised by t/format.t

  - Fixed a warning in t/html.t raised when neither Apache::Util nor
    HTML::Entities is installed.

2.06e 2002-03-12  ## DEVELOPER RELEASE ##

  - Fixed a minor bug in t/tiedhash.t which was trying to use the XS stash
    even if it wasn't enabled.  Thanks to Lyle Brooks for the patch.

  - Added the 'match' virtual method for matching a string against a
    regex and returning a reference to a list of (captured) (backrefs).

  - Changed html filter back into a fast and simple static filter.  Added
    html_entity filter which uses Apache::Util or HTML::Entities to do
    a complete and thorough (but slower) job.  The undocumented 'entity'
    option of the html filter is now removed (but may appear elsewhere).

  - Added the size virtual method for scalars to prove a consistent way
    of testing something.size to see if it has some value(s).  For scalars
    it returns 1.

  - Modified the 'sort' and 'nsort' list virtual methods to allow a sort
    key passed to represent a method to be called on objects in the list
    as well as the key of a value to be fetched from hash references in
    the list.  e.g. [% books.sort('author') %] allows 'books' to contain
    a list of hash refs with an 'author' key or objects with an 'author'
    method.  Thanks to Tony Bowden for suggesting this improvement.

  - Applied a patch from Simon Wilcox to strip MS-DOS \r characters from
    end of lines read by the Datafile plugin.

  - Applied a patch from Ville Skyttä which fixes numerous minor bugs
    in various splash templates.

  - Added the 'defined' and 'exists' virtual hash methods for testing if
    a value has a defined value, or exists in the hash, respectively.

  - Applied a patch from Stathy Touloumis to make the XS Stash thread safe.

  - Added the 'grep' virtual list method.

  - Applied a patch from Mark Fowler to improve the XML XPath plugin's
    handling of nested elements.

  - Fixed handling of prefix support in template() and insert() methods
    of Template::Content.  Any prefix is stripped from the name but passed
    as the second argument to the provider fetch() method.  e.g.
    [% INCLUDE foo:bar %] calls the foo $provider->fetch('bar', 'foo') and
    [% INCLUDE http://tt2.org/t/templates/hello %] results in a call to
    $provider->fetch('//tt2.org/t/templates/hello', 'http')

2.06d 2002-01-22  ## DEVELOPER RELEASE ##

  - Applied a patch to the DBI plugin from Simon Matthews to stop it
    from closing a DBH which was passed in open from an external source.

  - Applied another patch from Simon to fix a bug with compiled templates
    which were never being loaded due to a '<' comparison of timestamps
    rather than '<='.  See
    http://lists.tt2.org/pipermail/templates/2002-January/002361.html

  - Applied a patch from Doug Steinwand which fixes a minor bug in the
    XS Stash as reported by Andrey Brindeew:
    http://lists.tt2.org/pipermail/templates/2002-January/002475.html

  - Changed URL plugin to accept multiple values for CGI parameters, e.g.
    [% USE URL('/cgi-bin/foo', items=[10,20]) %] generates a URL like:
    /cgi-bin/foo?item=10&amp;item=20

  - Applied a patch from David D. Kilzer to Makefile.PL to add -I flags
    to the various invocations of perl that we missed, and also to add
    a clean/FILES target for WriteMakefile().  See.
    http://lists.tt2.org/pipermail/templates/2002-January/002431.html

  - Fixed Makefile.PL to warn, not die, about mandatory modules, leaving
    it to the definitions in the PREREQ_PM which the CPAN module can
    understand.  Thanks to Leon for waving the flag.

  - Applied Leon's doc patch to the Table plugin to demonstrate
    row/column transposition.

  - Added ucfirst and lcfirst filters to fold first character to upper
    or lower case respectively.  Thanks to Paul Makepeace for the patch.

  - Fixed truncate method of String plugin to not append suffix if the
    string is already shorter than the required length.  Thanks to
    Yann Kerhervé for the patch.

2.06c 2001-12-20  ## DEVELOPER RELEASE ##

  - Changed both Perl and XS Stash modules to try to apply a SCALAR_OPS
    virtual method to a blessed object as a last-ditch chance if all else
    fails.  Thanks to Tony Bowden for reporting the problem.  See
    http://lists.tt2.org/pipermail/templates/2001-December/002263.html

  - Added tie() method to DBI plugin which interfaces to the Tie::DBI
    module, based on some plugin code sent to me courtesy of Dave
    Hodgkinson.  Also made various minor cleanups to DBI code and updated
    documentation and tests.  Incidentally, this tickled the missing
    feature in the XS stash which doesn't yet support tied hashes.

  - Applied a patch from Christian Schaffner which fixes a problem in
    the Makefile.PL for installation via the fink package manager under
    Mac OS X.

  - Fixed up some of the ugliness in the docsrc tools.

2.06b 2001-12-02  ## DEVELOPER RELEASE ##

  - Added the Template::Plugin::Filter module to make plugin filters
    easier to write and rewrote the Template::Plugin::XML::Style to use
    it.

  - Added the Template::Plugin::String module which provides a nice
    object oriented approach to string manipulation.

  - Added the '_' string concatenation operator.  [% foo = bar _ baz %]

  - Applied Craig's suggested fixes to the parser to correct potential
    precendence problems and added tests to the test suite.  See:
    http://lists.tt2.org/pipermail/templates/2001-November/002138.html

  - Applied Leon's patch to Template::Service to delete the 'template'
    entry added to the variable hash at the end of processing.

  - Fixed an obscured bug/oversight in Template::Plugins which tested
    generated plugin objects for truth rather than definedness to see if
    the plugin returned was valid.  This can cause problems if your
    object has an overloaded stringification operator which gets called
    (but shouldn't) and could return an untrue (but correct) value.

  - Fixed t/dumper.t to only have one entry in each hash to avoid hash
    ordering problems.  Thanks to Randal for reporting the problem.

  - Added the assert() subroutine to Template::Test.

  - Added some more content to the FAQ.

2.06a 2001-11-19  ## DEVELOPER RELEASE ##

  - Added the XML::Style plugin for doing simple XML stylesheet like
    transformations and t/xmlstyle.t.

  - Fixed a bug in the DBI plugin where nested loops could cause the inner
    query to overwrite the _STH of the outer query causing the outer loop
    to end prematurely.  Thanks to Dave Hodgkinson, Craig Barratt and Simon
    Matthews for working on the problem and solution.  For more info, see
    http://lists.tt2.org/pipermail/templates/2001-November/002067.html

  - Applied a patch from Aleksey Nogin to Makefile.PL to call bin/gifsplash
    with the '-i' option.  This fixes the problem reported by Kenny Flegal:
    http://www.tt2.org/pipermail/templates/2001-November/002028.html

  - Applied a patch from Stas Bekman to add 'align' to template/html/row.

2.06 2001-11-07

  - Fixed a bug in t/compile5.t which caused the following test warning on
    Win32: "Cannot chdir to D/blah/blah/Template-Toolkit-2.05c/t/test: No
    such file or directory at t\compile5.t line 73".  Thanks to Chris
    Winters for finding the bug and testing the fix.

2.05d 2001-11-06  ## DEVELOPER RELEASE ##

  - Fixed a bug in the parser which was missing a '^' anchor on the regex
    matching the TAGS directive, causing it to match anywhere.  Thanks to
    Dominic Mitchell and Adrian Howard for reporting and fixing the problem.
    See http://lists.tt2.org/pipermail/templates/2001-October/001760.html

  - Modified Template::Parser to correctly handle "\t" and "\r" in double
    quoted strings as well as "\n".  Added test to t/parser.t

  - Applied a patch from Stas Bekman to add 'valign' as an option to the
    html/cell template.

  - Applied a patch from Harald Joerg to document the 3rd $default
    option to Template::Stash::set().

  - Fixed a problem in the docsrc build whereby double quote strings
    were causing embedded variables to be incorrectly interpolated, e.g.
    [% INCLUDE xyz title="set($var, $val, $default)" %] is now
    [% INCLUDE xyz title='set($var, $val,  $default)' %].  Thanks to
    Harald Joerg for reporting the problem.

2.05c 2001-10-22  ## DEVELOPER RELEASE ##

  - Applied a patch from Tony Payne which fixes a bug where templates were
    being mangled under mod_perl due to a missing O_TRUNC on a sysopen().
    See http://www.tt2.org/pipermail/templates/2001-October/001834.html

  - Fixed the mess I made of Pudge's XS Stash patch applied in 2.05b.

  - Updated the INSTALL/README guides to note the PPM installation for
    Win32 users.

2.05b 2001-09-21  ## DEVELOPER RELEASE ##

  - Applied a patch from Chris Nandor to bring the XS stash in line with
    the regular Perl stash wrt accepting defined but empty keys.  See
    http://www.tt2.org/pipermail/templates/2001-September/001695.html

  - Applied a patch to Template::Provider from Craig Barratt to fix
    a bug when caching is turned off (CACHE_SIZE = 0).  See
    http://www.tt2.org/pipermail/templates/2001-September/001682.html

  - Moved installation out of README into a separate INSTALL file and
    added the HACKING document as a pointer to the internals docs.

  - Added the 'uri' filter for URI escaping text.

2.05a 2001-09-12  ## DEVELOPER RELEASE ##

  - Applied a patch from Chris Nandor to use 'MSWin32' as a specific O/S
    detection rather than /win/i which gives a false positive for 'Darwin'.
    Needless to say, that's something of an insult to Darwin  :-).  Also
    fixes Template::Provider to use File::Spec::file_name_is_absolute() to
    test for absolute paths instead of the previous kludge.

  - Updated Template::Manual::Internals to include information about
    how to prepare patches and other useful information for potential
    TT hackers.

  - Added some code to the XS Stash to handle trivial access to tied
    hashes.  Regular set/get/default should work as expected, but at
    present intermediate hashes are not auto-vivified on assignment,
    e.g. [% these.dont.get.created.in.XS.but.do.in.the.perl.stash = 10 %]

2.05 2001-09-11

  - Bumped version number and updated documentation for release.

2.04f 2001-09-10  ## DEVELOPER RELEASE ##

  - Fixed a bug in the Date plugin which was performing one localtime() too
    many when a date was passed in to the format() method.  e.g. the result
    from date.format('12:59::00 30/09/2001', '%H:%M') was 13:59 not 12:59.
    Thanks to Thierry-Michel Barral and Matthew Tuck for reporting the
    problem.

  - Incorporated Doug's new version of the XS Stash.  It fixes the problem
    with strings not being recognized as integers (and the item = item + 1
    problem). It also adds a few additional tests for this situation to
    t/stash-xs.t

  - Fixed a minor bug in Makefile.PL which looked for 'msql' or 'mysql' as
    the default DBD for testing DBI but didn't select a suitable default
    if the above drivers weren't available.

2.04e 2001-09-06  ## DEVELOPER RELEASE ##

  - Fixed bug in 'list' entry in $HASH_OPS in both Template/Stash.pm and
    Template/Stash/Context.pm to return '%$hash' instead of 'values %$hash'.
    Thanks to Craig Barrett for reporting the problem.

  - Applied a patch from Craig to Stash.pm and Stash/Context.pm to
    accept negative integers as array indices, counting back from the
    end of the list as in Perl.  This brings it into line with the new
    XS Stash.
    http://www.tt2.org/pipermail/templates/2001-August/001493.html

  - And another patch from Craig to allow $var and ${var} to be used as
    keys in hashes.
    http://www.tt2.org/pipermail/templates/2001-August/001410.html

  - Modified Template::Plugins fetch() method to accept $factory as a
    code reference.  Then changed _load() to return a closure for
    regular Perl modules loaded (via LOAD_PERL option) which, which
    called by fetch(), removes the first argument, the $context
    reference, which the non-plugin module won't be expecting.  This
    fixes the problem reported (and also fixed but in a slightly
    different way) by Lyle Brooks, here in these messages:
    http://www.tt2.org/pipermail/templates/2001-August/001397.html
    http://www.tt2.org/pipermail/templates/2001-August/001406.html

  - Removed the eq, ne, gt, lt, ge and ne operators added in 2.04d.  Given
    that they can (and did) break code that had existing variables with
    those names, I decided it was best to strip them out again and think
    more carefully about adding them to an official release.  Hence they're
    not going to be in 2.05.

  - Fixed an outrageous oversight in the HTML 'rgb' template by defining
    'orange' as a valid colour (I can't believe Leon hasn't already sent
    me a patch for this!)  Created a new custom colour scheme in the
    Makefile.PL which uses it.  Hacked the Makefile.PL and the generated
    ttree config file to allow text colours to be specified as well as
    button background colours.

2.04d 2001-08-29  ## DEVELOPER RELEASE ##

  - Incorporated Doug Steinwand's XS Stash.  This adds the files in the
    'xs' directory, t/stash-xs.t, bin/tt-bench.pl and includes some work
    on the Makefile.PL to incorporate the required prompting, etc.

  - Added gt, ge, lt and le as comparison operators which map directly
    to their Perl counterparts.  Added tests to t/stash.t and relevant
    documentation to the IF directive.

  - Applied some patches from Leon and Doug to enhance the coverage of
    the test suite.

  - Added 'sorted' as a flag to the HTML plugin to return attributes in
    sorted order.  Mainly for debugging purposes, as used in t/html.t.

  - Fixed Template::Parser.pm to recognise "\r" as a valid escape sequence
    in double quoted strings.

2.04c 2001-08-04  ## DEVELOPER RELEASE ##

  - Fixed t/dbi.t and t/latex*.t to not complain about "Test header seen
    twice".  Thanks to Leon.

2.04b 2001-08-04  ## DEVELOPER RELEASE ##

  - Fixed a bug in the Makefile.PL which prevented the correct targets
    from being added to the generated Makefile to install additional
    components, build HTML docs, etc.

  - Applied a patch from Chris Nandor to fix a bug introduced by the taint
    checks in 2.04 which barfed on ';' in filenames.  Also changes open()
    to sysopen() in Template::Document for additional security.  See
    http://www.tt2.org/pipermail/templates/2001-August/001348.html

  - Another part of the same pudge patch adds FACTORY as a default value
    to Template::Parser to allow Template::Directive factory class to
    be replaced.

2.04a 2001-07-05  ## DEVELOPER RELEASE ##

  - Changed GD plugin and tests to require GD version 1.20.  See
    http://www.tt2.org/pipermail/templates/2001-July/001212.html

  - Applied Craig's fix for the DBI plugin to correctly destroy a
    statement handle to ensure that finish() gets called on it even if the
    iterator doesn't complete.  See:
    http://www.tt2.org/pipermail/templates/2001-July/001216.html

  - Further to Craig's points in the above post, I added get_all() and
    get() to the DBI iterator so that you can now do this:

    [% people = DBI.query(...) %]
    [% person = people.get %]   # first person
    [% person = people.get %]   # second person
    [% FOREACH person = people.get_all %]
       # third to nth person(s)
    [% END %]

  - Fixed Template::Provider which wasn't saving compiled templates to
    disk when specified with an absolute path, as reported by Merlyn.  See
    http://www.template-toolkit.org/pipermail/templates/2001-July/001213.html

  - Updated Makefile.PL to accept various command line args including
    TT_ACCEPT to automatically accept all default values and TT_QUIET to
    shut the file up with all those yackety yack, yack messages.

2.04 2001-06-29

  - Applied a patch from Craig Barratt to both the regular
    Template::Stash and the alternate Template::Stash::Context which
    allows array indexes into hashes and arrays (slices) in the same
    manner as Perl.  For example:

      [% keys = [ 'foo', 'bar' ]
         vals = hash.$keys	# [ hash.foo, hash.bar ]

         keys = [ 2, 3, 7 ]
         vals = list.$keys        # [ list.2, list.3, list.7 ]
      %]

  - Applied another patch from Craig to Parser.pm which fixes a bug
    relating to text strings being interpolated in a numerical context.
    See: http://www.tt2.org/pipermail/templates/2001-April/000901.html

  - Applied yet another patch from Craig ("Man of the Patch" for v2.04 :-),
    to fix a problem with NEXT not working inside switch:

      FOREACH and WHILE now get a LOOP: label, and NEXT and LAST now
      generate "next LOOP;" and "last LOOP;".  However, the original
      code allows naked "NEXT" or "LAST" (which behave like STOP).  I
      didn't want to change this behavior, so NEXT and LAST only get the
      LOOP label inside loops (except in the top-level atomexpr FOREACH
      and atomexpr WHILE cases, which should be ok).

  - Does he ever sleep!  :-) Another patch from Craig to improve upon
    the ref->template mapping feature in Template::View.  Documentation
    pending.  For further details, see
    http://www.tt2.org/pipermail/templates/2001-June/001161.html

  - Applied a patch from Mark Fowler, which fixes the problem with
    search/replace virtual methods incorrectly returning with a search
    pattern of '0'.  e.g. [% bob = '0'; bob.replace('0', 'zero') %]
    now returns 'zero' instead of ''.

  - Applied a patch from Doug Steinwand to prevent the Stash from
    raising undef error reporting 'Can't locate object methof "bar" via
    package "Foo"' unless $DEBUG is enabled.

  - Applied a patch to the DBI plugin from Rafael Kitover which calls
    the DBI connect_cached() method instead of connect() to allow
    connection caching in a persistent server environment (e.g. Apache
    mod_perl).

  - Changed html filter to be a dynamic filter factory, allowing the
    'entity' option to be set to prevent entities of the form
    '&word;' being converted to '&amp;word;'

      [% FILTER html(entity = 1) %]
         < &amp; >		    # &lt; &amp; &gt;
      [% END %]

  - Changed Template::Stash to propogate any object errors that
    are references (e.g. Template::Exception objects or otherwise)
    or string that don't look like "Can't locate object method ...".

  - Fixed various typos in docsrc/xml/ttdocsrc with a deft:
    s/Plugin::GD::Graphs/Plugin::GD::Graph/g;

  - Applied a patch from Leon Brocard to remove a suspect test from
    t/filter.t which Chris Nandor reported as causing problems.

  - Added Craig's comments on replace backreferences and TT grammar to
    TODO list.

  - Applied various patches from Leon: to remove redundant "print 1..0"
    in various t/*.t files; to add '1;' to end of '.defaults.cfg' file;
    and to fix t/vmeth.t and t/leak.t to run correctly under latest
    bleadperl.

  - Applied a patch from Jonas Liljegren to fix problems with errors
    being raised in -T taint mode.

  - Fixed another problem identified by Jonas so that filters are no
    longer cached.  See:
    http://www.tt2.org/pipermail/templates/2001-June/001192.html

2.03 2001-06-15

  - Added new virtual methods 'item', 'list', 'hash' to each of scalar,
    list and hash ops to Do The Right Thing to convert the original value
    to what the caller wants.  This is based on a patch supplied by Craig
    Barratt...

  - ...which implements a number of new features to the stash, most
    notably the ability to specify the context in which you want an
    object method or subroutine to be called in by appending '.list' or
    '.scalar' to a dotted variable.  e.g. [% cgi.param('foo').scalar %].
    I haven't folded this patch into the core Stash yet (other than
    adopting the virtual methods described above) but it's provided as
    an alternate stash implementation, Template::Stash::Context, which
    you can create and specify to your Template object via the STASH
    configuration option.  I'd like to a) benchmark it and b) give
    people the option of trying it out (and hacking on it?) before
    integrating the new features into the default stash.

  - Applied a patch to add the Latex filter and GD plugin functionality,
    thanks to the excellent work of Craig Barratt and Richard Tietjen.
    In Craig's words:

      Here is a new version of my Latex filter and GD plugin code.
      (This adds a latex filter that supports PDF, PS and DVI output,
      plus 16 or so plugins for the GD::* modules, allowing PNG, GIF
      output.)

      [Includes] Richard Tietjen's changes for the latex filter for WinXX
      [which] didn't make it into the May 20th version.  The new version
      includes the correct changes for WinXX and also now has been
      tested against TexLive and MikTeX on WinXX.

    Craig's patch also included full documentation so you can read all about
    it in the Manual and Module pages.  In addition, the Makefile.PL now
    searches for GD modules and external Latex programs and does some extra
    user prompting for confirmation of Latex installation/configuration.
    Not only that, but Craig also managed to roll in a couple of other
    minor bug fixes and documention updates.  Nice work!

  - Fixed the parser to accept fully dotted up variable assignments in
    argument lists, e.g. in INCLUDE, etc.  You can now do this:

    [% INCLUDE html/head
        html.head.title = 'My Title'
    %]

    Note however that the assignment to such variables is always "global",
    even though INCLUDE claims to localise the stash.  Remember that the
    localisation does not perform a deep copy so the localised copy of
    the 'html' variable might just be a copy of the reference to a previously
    defined hash array.  Thus, you modify the original albeit via a copy
    of the reference to it.  See INCLUDE section of
    Template::Manual::Directives for further details.

  - Added 'base' option to Template::View.  This allows one view to inherit
    from another "base class" view.  If a template isn't defined in a
    derived view then it automatically asks its base view for it, and so
    on up the inheritance tree.

      [% VIEW myview.default
              prefix = 'view/default/';
         END
      %]
      [% VIEW myview.fancy
              base   = myview.default
              prefix = 'view/fancy/';
         END
      %]

    In this example, [% myview.fancy.header %] will be resolved as
    [% INCLUDE view/fancy/header %] or [% INCLUDE view/default/header %]
    if 'view/fancy/header' doesn't exist.  Variables are also inherited.

  - Added the 'sealed' and 'silent' parameters to VIEW to allow view to be
    optionally unsealed (allow external variable updates/creation) and
    to silence warnings about attempts to update sealed variables,
    respectively.  See the Template::Manual::Views page for more info on
    this and previosu item.

  - Added the HTML plugin for generating (very basic) HTML elements.
    See the Template::Plugin::HTML documentation.

  - Added the present() and content() methods to XML::DOM::Node in the
    XML::DOM plugin to make them work harmoniously with VIEWs.  See the
    Template::Plugin::XML::DOM documentation for further details.

  - Did the same for Template::Plugin::XML::XPath, adding present($view)
    and content($view) methods to XML::XPath::Node::Element and a
    present($view) method to XML::XPath::Node::Text.  See the
    Template::Plugin::XML::DOM documentation for more details.

  - Added the calc() method to the Date plugin to return an interface to
    the Date::Calc module.  e.g.

      [% USE Date; calc = Date.calc %]
      [% calc.Monday_of_Week(22, 2001).join('/') %]

  - Moved Template::Tutorial to Template::Tutorial::Web and added the
    tutorial kindly donated by Dave Cross on generating and using data
    files with TT as Template::Tutorial::Datafile.  Template::Tutorial
    is now an index to the tutorials.

  - Changed the bin/tt2inst script to no longer use the 'no_chdir' option
    of the File::Find module which isn't supported in earlier version such
    as distributed with pre-5.6.0 Perl.  Thanks to a patch from Vivek
    Khera <khera@kcilink.com>.  Changed Makefile.PL to accept File::Spec
    version 0.6 or later.

  - Fixed a bug in the FOREACH directive which would barf with the error
    "undef error - loop is undefined" when DEBUG was enabled.

  - Applied a patch from Eric Cholet to fix a bug in META data items not
    correctly escaping ' and \ characters.

  - Applied another patch from Eric to fix "Use of uninitialised value"
    warning when using a subclassed parser.

  - Applied a patch to ttree from Leon Brocard print full path for ignored
    files.

  - Fixed typo in the ttree help page which incorrectly listed debug
    mode as '-d' (now '-dbg' as well as '--debug')

  - Fixed (hopefully once and for all!) the problem with choming the
    final newline in a template.  The last newline is now chomped just
    like any other, depending on the POST_CHOMP flag and/or trailing '-'
    in the directive.  e.g.

      [% FILTER latex('ps') %]
         ...
      [% END -%]

    If you explicitly want a newline then make sure one is added to the
    end of the template and don't enable POST_CHOMP or add a trailing '+'
    in the directive, e.g.

      [% INCLUDE footer +%]

  - Made a number of fixes to the HTML generated by the Splash! and HTML
    libraries to make it conformant with HTML 3.2 specificiation.  Added
    DOCTYPE to html/header, ALT tags, ... added html/head, html/body and
    html/html to do more thorough job using nested variables.  Also added
    html/config to load HTML plugin.  Full conformance is still an issue,
    but we're working on it...

2.02 2001-04-06

  - Updated various components of the Splash! library, cleaned up some
    ugliness (a little) and revised the examples.  Documentation in
    Template::Library::Splash is now hopelessly out of date but examples
    are more comprehensive.  Makefile.PL now prompts user to select a
    colour scheme for creating the documentation and examples.

  - Fixed problems with Splash! images displaying the "wrong" colour on
    certain systems.  It appears to be the case that this was automatic
    gamma correction at work, an otherwise very cool feature of PNG
    files.  Alas it broke things here so we've switched to GIF files.
    Also made an improvement to the way of generating and using the
    images.  By using simple transparency and doing away with the
    anti-aliasing it's possible to support any foreground colour for a
    set of images in a background colour.  One set of black images are
    now distributed with TT.  These are blown into many colours during
    installation, implemented by the bin/gifsplash script and defined
    as the 'tt2_splash' Makefile target, run automatically as part of
    'make install'.

  - Changed redirect filter factory and the underlying Template::_output
    method to accept a 'binmode' flag.  The bin/gifsplash script sets
    this flag to ensure that the GIFs generated for Splash! are valid on
    Win32 platforms (it's a good job SAM knows what binmode is for... :-)

  - Applied a patch from Leon Brocard to add 'recurse' and 'verbose'
    options to the ttree.cfg files generated by Makefile.PL.  Their
    absence was preventing the docs and examples from being built
    (unless, like the stupid author, you already had a default
    ~/.ttreerc which included these flags :-).

  - Fixed Makefile.PL to check for File::Spec 0.82, thanks to the efforts
    of Doug Steinwand and Leon who found and fixed the problem with
    'splitdir' otherwise not being available.  Later changed requirement
    from 0.82 to 0.80 because this is the version currently distributed
    with ActivePerl 5.6.0 and it appears to work just fine (saves those
    poor Win32 users from having to install any more modules than
    absolutely necessary)

  - Removed test for platform specific error messages from t/xpath.t
    Removed warning from README that this test would fail.  Thanks
    again to Leon for the patch and to <umun@yahoo.com> (no name
    given) for reporting the problem.

  - Applied another patch from Leon to fix Template::Base.pm to avoid
    "Use of uninitialized value..." warnings.

  - Applied yet more patches from Leon to add "use Template::Plugin" or
    something similar to the File, Directory and View plugins.  'use
    base' doesn't work as advertised (e.g. in ensuring the module is
    loaded) in older versions of Perl.

  - Fixed t/leak.t to only run one particular test if Perl version is
    5.6.0 or greater.  Test fails on earlier versions due to destructors
    being called in a different order.

  - Updated Makefile.PL to supply a more typical default installation
    directory for Win32 systems - C:/Program File/Template Toolkit 2/.
    This brought to light numerous bugs (following) which were fixed
    with the invaluable help of Simon Matthews and Theakston's Black
    Sheep Ale... :-)

  - Pathnames generated in the Makefile.PL for the Makefile are now all
    "double quoted" to protect embedded whitespace, e.g. when building
    docs: ttree -f "C:/Program Files/...")

  - Patched Template/Provider.pm in several places to strip out any
    extra ':' characters put in the wrong place of a path.  For example,
    when writing compiled template "C:/foo" to disk with a COMPILE_DIR
    of "C:/bar", the resulting file is now "C:/bar/C/foo" instead of
    the erroneous "C:/bar/C:/foo".

  - On Win32 systems, provider prefixes must be more than 1 character in
    length.  This is a compromise for cases where you might want to do
    something like: [% INCLUDE C:/foo/bar %].  Remains unchanged on
    other platforms.

  - On Win32 systems the DELIMITER now defaults to a slight variation of
    ':' if not otherwise set.  It now uses /:(?!\/)/ to split on ':'
    where not followed by '/'.  This makes things like INCLUDE_PATH =>
    'C:/here:C:/there' work properly, although setting a more suitable
    DELIMITER for Win32 systems (e.g. ';') is still recommended (we tried
    automatically setting it to ';' on Win32, but that caused more problems
    than it was worth).

  - Changed Template::Provider to consider a file starting (\w:)?/ as an
    ABSOLUTE path when running on Win32 (e.g. C:/foo).  On other
    platforms, it remains unchanged, looking only for a leading '/'.
    Also changed ttree to do the same, so that 'ttree -f C:/test.cfg'
    is treated as an absolute path and it doesn't try and prefix it
    with the ttree configuration file directory.  Note that ttree
    does this regardless of OS.

  - Fixed stringification problem identified by SAM.  Objects that have
    auto-stringification sometimes didn't get properly stringified at the
    right time.  e.g. [% a = "$an_obj" %].

  - Fixed File and Directory plugins to gracefully ignore Perl dying with
    "getpwuid() not supported on this platform" errors on Win32.  The
    'uid' and 'user' attributes of File and Directory plugin objects
    are left undefined.

  - Then, hacked t/file.t and t/directry.t test to not be run under
    Win32.  There are a couple of outstanding minor problems with these
    test scripts caused by differences in '/' and '\' as path
    separators.  Need to fix these at some point.

  - Makefile.PL now saves configuration options in '.defaults.cfg'
    file, using these values as defaults when run again.

  - Removed duplicated $VERSION from DBI and XML::DOM plugins, thanks
    to Jonathan Leffler.

  - Updated documentation to reflect new changes.

2.01 2001-03-30

  - Added the various template libraries in the 'templates' directory.
    The 'html' library implements some generally useful HTML elements.
    The 'pod/html' libraray contains some templates for converting POD to
    HTML, used in building the TT2 HTML documentation, for example.  The
    'ps' library contains templates defining a few useful marks and other
    procedures for generating PostScript pages.  The 'splash' directory
    contains templates for the "Splash!" library which implements a
    widget set for building stylish HTML user interfaces.

  - Added a host of example pages in the 'examples' directory which
    demonstrate use of the above libraries.

  - Added an 'images' directory to contain the small images used to build
    up the Splash! interface components.

  - Added the 'docs' directory containing templates and library elements
    for building the TT2 documentation as HTML pages.

  - Updated Makefile.PL to now offer to install optional libraries,
    images, build HTML docs, examples, etc.  Adds 'tt2_install',
    'tt2_html_docs' and 'tt2_examples' as Makefile targets if requested.
    These then get run as part of "make install".

  - Totally re-organised the documentation, splitting the long user manual
    into separate Template::Manual::* pages, adding the Template::FAQ,
    Template::Internals, and various other changes.  All POD and HTML
    documentation is built from the same sources in the form of another
    set of templates, POD files, XML files, scripts, etc., distributed
    separately as the 'docsrc' bundle, and available from the web site.
    The POD documentation now gets glued onto the end of the .pm
    modules and only creates separate .pod files for those manual pages
    that don't have equivalent modules (e.g. Template::FAQ, etc.)
    NOTE: this might mean that existing .pod files from earlier versions
    of TT might mask documentation in newer .pm files...

  - Added the Template::View module, the VIEW directive and the View
    plugin which can be used collectively to create dynamic views.  This
    is a very powerful tool which fulfills a number of requirements and
    makes possible a number of things that have previously been messy,
    difficult or not possible.  Views are primarily collections of
    templates.  You can define BLOCKs within a view and they remain
    local to it, but can be called from outside the view.  This is still
    very experimental.  Things are likely to change.  See
    Template::Views for (incomplete) documentation and take a look at
    t/view.t for examples.

      [% VIEW fancy_html
  	    prefix = 'splash/'		# template prefix/suffix
  	    suffix = '.tt2'
  	    bgcol  = '#ffffff'		# and any other variables you
  	    style  = 'Fancy HTML'       # care to define as view metadata,
  	    items  = [ foo, bar.baz ]	# including complex data and
  	    foo    = bar ? baz : x.y.z  # expressions
      %]

  	[% BLOCK header %]		# define "private" view blocks
  	   Title: [% title %]
  	[% END %]

      [% END %]				# end of VIEW definition

      [% v = fancy_html %]		# view is a regular object ref, re-
      [% mycode(v) %]			# assign it, pass it around, etc.

      [% v.title %]			# access view metadata

      [% v.header(title = 'Foo!') %]	# view "methods" process blocks or
      [% v.footer %]			# templates with prefix/suffix added
  					# => [% INCLUDE splash/footer.tt2 %]

  - Added the facility to specify multiple templates within a PROCESS,
    INCLUDE, INSERT or WRAPPER directive.  For all but WRAPPER, the
    templates are processed in the order specified.

      [% PROCESS config + header + menu %]
      [% INCLUDE section/break + html/titlebar
           title='A New Section'
      %]
      [% WRAPPER edge + box + titlebar %]
         ...
      [% END %]

    Multiple WRAPPER templates get processed in reverse order to create
    the correct nesting effect.  In the example above, the enclosed block
    is processed and passed to 'titlebar' which wraps it and passes the
    output to 'header' which wraps it and passes the output to 'box', which
    wraps it and passes the output to 'edge' which wraps it and returns the
    output.  Thus the specification order is outermost to innermost, but
    they are actually processed from the inside out.

  - Templates specified to INCLUDE, PROCESS, WRAPPER and INSERT can now
    be given a prefix (delimited by ':', as in "file:blahblah.txt" or
    "http://www.tt2.org/index.html", for example) which maps them to a
    particular template provider or providers.  A PREFIX_MAP
    configuration option can be specified as a hash array mapping prefix
    names to a reference to a list of providers.  For convenience, you
    can also specify the argument as a string of integers, delimited by
    any non-numerical sequence, to indicate indices into the LOAD_TEMPLATES
    provider list.  e.g.

      my $template = Template->new({
  	LOAD_TEMPLATES => [ $foo, $bar, $baz, $wiz ],
  	PREFIX_MAP => {
  	    src => '0, 2',	# $foo and $baz
  	    lib => '1, 2',	# $bar and $baz
  	    all => '0, 1, 2',	# $foo, $bar and $baz
  	}
      });

    Thus [% INCLUDE src:hello.tt2 %] indicates the 'hello.tt2' template
    to be provided by $foo or $baz, [% INCLUDE lib:hello.tt2 %] is mapped
    to $bar and $baz, [% INCLUDE all:hello.tt2 %] can be provided by
    $foo, $bar or $baz, and the default [% INCLUDE hello.tt2 %] is
    mapped to the entire LOAD_TEMPLATES list: $foo, $bar, $baz and $wiz.
    This is initially useful for things like ttree which would like a way
    to differentiate between templates in one place and templates in
    another.  It can also be used, of course, to provider special providers
    for certain file type, as in http://fetch.some.file.com/blah/blah/...

  - Fixed the parser to accept expressions on the right hand side of
    parameter definitions for INCLUDE, etc.  e.g.

      [% INCLUDE header
           title = my_title or your_title or default_title
           bgcol = (style == 'dark' ? '#000000' : '#ffffff')
      %]

  - Added the PLUGIN_FACTORY configuration option to Template::Plugins
    to allow class names or object prototypes to be specified for plugins.
    No module loading is attempted, unlike the existing PLUGINS which
    assumes entries are module names which it tries to load.  This may
    change in a future release (ideally by integration with PLUGINS) so
    it remains undocumented for now.

      package My::Plugin;
      ...

      package main;

      my $tt = Template->new({
  	PLUGIN_FACTORY => {
  	    plugin1 => 'My::Plugin',         # class name
  	    plugin2 =>  My::Plugin->new(),   # prototype obj
  	},
      });

  - Added the File and Directory plugins which blossomed from the
    Directory plugin written by Michael Stevens and posted to the
    mailing list.  These give you access to files and directories on
    your filesystem and also allow you to create representations of
    abstract files/dirs.

    WARNING: recognise that this gives the author of any templates you
    run access to information about your filesystem.  We assume that the
    author of your templates is you or someone you trust to have access
    to that kind of information.  If you're running "untrusted"
    templates (we assume you know what you're doing) then you'll very
    probably want to disable these plugins.  Alas there is no easy way
    to disable plugins at the moment other than deleting them or writing
    null or error throwing plugins to mask them.  Making this easier is
    a TODO.

  - Added the Pod plugin which uses the Pod::POM module to parse a Pod
    file or text string and build an object model.  You can then walk
    it and present it in different ways using templates.  Great for
    building HTML documentation from Pod and unsurprisingly used to
    build the new TT2 docs.

  - Applied a patch from Chris Nandor to add a new feature to the
    PRE_CHOMP and POST_CHOMP options.  When set to 1, they continue to
    act as before.  When set to 2, all whitespace is collapsed into a
    single space.  CHOMP_NONE, CHOMP_ALL and CHOMP_COLLAPSE are
    defined in Template::Constants and can be imported as the :chomp
    tagset, for those who want them.

  - Applied a patch from Doug Steinwand to fix a problem in
    Template::Provider which would server stale templates if the
    modification time of the files went backwards.  In addition, it now
    uses the $Template::Provider::STAT_TTL (time to live) variable
    (default: 1) to determine how often to stat the files to check for
    changes.  TT2 now supports time running backwards!  :-)

  - Applied a patch from Vivek Khera which fixes a memory leak in the
    MACRO directive, prevalent when using TT under mod_perl.  Also added
    t/leak.t to test that memory is properly freed and circular references
    broken by the delocalisation of the stash.  All seems to work as expected
    including plugins that contain context references, MACRO definitions,
    and so on (but note that this is the test suite run from the command
    line, and doesn't explicitly test under mod_perl...)

  - Applied a patch from Axel Gerstmair to fix a bug in PERL blocks
    and filters which caused references to the context and stash to be
    kept in global package variables.  This meant they stayed alive for
    far too long.  Added a couple of tests to t/leak.t to check this now
    works OK.

  - Fixed a bug in the parser triggered by [% CATCH DEFAULT %].  Thanks
    to Vivek Khera for reporting the problem.  This also fixes a problem
    reported by Thierry-Michel Barral which was causing bare 'CATCH'
    blocks to not catch errors and instead pollute STDERR.

  - Fixed another bug in the parser preventing double quoted META attributes
    from containing single quotes, e.g. [% META title="C'est un test" %].
    Thanks to Philippe Bruhat for reporting the problem.

  - Added the 'indent' filter to indent a block by prefixing each line with
    a specified string, or a number of spaces when the argument is numerical.

  - Added the 'trim' filter to remove leading/trailing whitespace and
    'collapse' filter to additionally collapse multiple whitespace characters
    to a single space.

  - Added escapes for ' (&apos;) and " (&quot;) to the html filter, thanks
    to Lyle Brooks and Vivek Khera.  Then, having done that, I removed
    the &apos; escape because my browser didn't recognise &apos; as a
    valid entity.  What's going on here?  Need to check the HTML spec...

  - Added tag style 'star' of the form [* ... *]

  - Changed the Template::Stash get() and set() methods to accept a
    compound variables as a single parameter and automatically convert
    it to an array.  Note that it doesn't correctly handle arguments
    to dotted elements (e.g. foo(10).bar(20), but does mean that you can
    now write $stash->get('foo.bar.baz') instead of the more laborious
    $stash->get(['foo', 0, 'bar', 0, 'baz', 0]).

  - Fixed a bug in Template::Stash which was raising an error when an
    element on the left hand side of a '.' evaluated to a defined, but
    empty value.

  - Fixed an obscure bug in Template::Stash which occurred when calling
    a scalar method on a value which contained a valid and visible object
    package name.  e.g. [% name = 'Foo::Bar'; name.baz() %] called
    Foo::Bar->baz().

  - Fixed a bug in the Template::Stash 'replace' virtual method which
    returned the original string when the replace string was specified
    empty.   [% var = 'foo99'; var.replace('foo', '') %] now correctly
    returns '99' instead of the original string 'foo99'.  Thanks to
    Tryggve Johannesson and Jeremy Wadsack for reporting the problem.

  - Added magical handling of the 'import' variable to stash clone() and
    update methods.  This implements the V1 functionality whereby you can
    write [% INCLUDE foo import=myhash %].  Note that 'import' is lower case,
    (V1 was upper case IMPORT) as in V2 it is in keeping with the virtual
    hash method (e.g. same as myhash.import(another.hash)).  Thanks to
    Brian Cooper for raising the issue.

  - Yet another change to Template::Stash.  Objects which are blessed
    arrays will now honour virtual array methods if the object doesn't
    otherwise implement a particular method.  For example, you can now
    write [% USE Datafile(...) %] and then [% Datafile.size %].  The
    '.size' now works as virtual method on the blessed ARRAY which
    consitutes the Datafile object.  Thanks to Keith Murphy for
    identifying the problem.

  - Fixed another obscure bug, this time in Template::Parser which wasn't
    chomping the final newline in the input string.  Thanks to Paul
    Makepeace for reporting the problem.

  - Finally identified the cause of an error occasionally being reported
    by Template::Service when is thrown a non-reference exception.  It
    appears to be a problem interacting with CGI::Carp.  For now, it's
    fixed and tolerated in Template::Service (but could possibly do with
    a better long term solution?).  Thanks to Jo Walsh, Trond Michelson,
    and I'm sure several others who reported this and helped to track
    the problem down (and also fixing the confess() bug I introduced
    when I added the tracer code.  D'Oh!)

  - Removed some old "delegate-to-another-object" code from Template::Plugin,
    including a nasty AUTOLOAD method which prevented derived objects from
    acting as transparent hashes.  If delegative functionality is required
    then it should be implemented as Template::Plugin::Delegate (and may
    well be in the fullness of time).

  - Fixed a whole bunch of typos and spellos thanks to patches from Leon,
    Paul Sharpe and Robert McArthur.

2.00 2000-12-01

  - Added the repeat(n), search(pattern) and replace(search, replace)
    virtual methods for scalars, and fixed a warning in the split()
    method raised when an attempt was made to split an undefined value.

  - Changed the THROW directive to accept multiple parameters which
    become named items of the 'error.info' item, thanks to a suggestion
    from Piers Cawley.  Positional arguments can be addressed as
    [% error.info.n %] or as a list as [% error.info.args %].  Named
    parameters can be accessed as [% error.info.name %].
    e.g.
      [% TRY %]
      [% THROW foo 'one' 2 three=3.14 %],
      [% CATCH %]
         [% error.type %]        # foo
         [% error.info.0 %]      # one
         [% error.info.1 %]      # 2
         [% error.info.three %]  # 3.14
      [% END %]

  - Moved the definition of Template::TieString from Template::Directive
    into Template::Config (for now) to ensure that its definition is
    visible even if the Template::Parser, and through it, the
    Template::Directive module, haven't been loaded.  This fixes the
    bug causing the error "Can't locate object method "TIEHANDLE"
    via package Template::String..." raised when using EVAL_PERL with
    compiled templates only.  In this case, the parser wasn't getting
    loaded (because it had no templates to parse, them all being pre-
    compiled) and the Template::TieString defintion wasn't visible to
    the EVAL_PERL blocks that require it.  Added a test to t/compile3.t.
    Thanks to Igor Vylusko for reporting the problem.

  - Changed the Template::Directive Perl generator for EVAL_PERL blocks
    to generate code to first test the EVAL_PERL option in the runtime
    context and throw a 'perl error - EVAL_PERL not set' exception if
    unset.  Thus the behaviour for EVAL_PERL when using compiled templates
    is now: if the EVAL_PERL option isn't set in the _compiling_ context,
    then Perl code will be generated which *always* throws an exception
    'perl error - EVAL_PERL not set'.  If EVAL_PERL is set, then it will
    generate code which tests the EVAL_PERL option in the _running_
    context (which may not be the same context that compiled it), and
    throws the same error is the option is not set.  Note that [% RAWPERL %]
    blocks are added verbatim to the generated code if the EVAL_PERL
    option is set in the compiling context and no runtime check for
    EVAL_PERL is made.  Similarly, [% PERL %] blocks could contain a
    Perl BEGIN block, e.g. "BEGIN { # subterfuge code here }" which
    will always get executed at runtime, regardless of any runtime
    EVAL_PERL option.  Thanks to Randal Schwartz for raising this issue.

  - Fixed an obscure bug in WRAPPER which was causing some variables to
    have apparently strange values when within the block content.  This
    was due to the content being formed into a closure which was called
    from within the WRAPPER template, possibly after some variable values
    had been changed.  e.g.
      [% title = "foo" %]
      [% WRAPPER outer title="bar" %]
         The title is [% title %]
      [% END %]
    Here, the 'outer' template should be called with a 'title' value of
    'bar' but with 'content' set to 'The title is foo'.  Previously,
    the content would have been processed from within the 'outer' template,
    resulting in a 'content' value of 'The title is bar'.  The behaviour is
    now correct.

  - Filter failures are now raised as 'filter' exception types, instead
    of 'undef'.

  - Applied a patch from Simon Matthews to fix some minor bugs in the
    DBI plugin:

    - Added _connect method to Plugin::DBI for backwards compatability with
      code from version 1 of Template that subclassed the plugin

    - Changed the new mothod on the DBI plugin so that it checks to see if
      it is being called by a subclassed object.

    - Fixed the return value in the DBI plugin when connect is called more
      than once in the lifetime of the plugin

  - Removed a dubious looking chomp() from Template::Plugins which may
    have caused abject stringification of any error object throw by a
    failed plugin constructor.  Thanks to Piers Cawley for finding the
    devious culprit.

  - Changed ttree to not offer to create a ~/.ttreerc file if it doesn't
    exist when the user has specified a '-f file' on the command line.
    Thanks to Michael Stevens for raising the issue.

  - Added the match($result, $expect) subroutine to Template::Test.

  - Modified the final test of wrap.t to strip any trailing whitespace from
    the output due to a problem with Text::Wrap under 5.005_02.  Thanks to
    Rob Stone for reporting the problem.

  - Added documentation for DEBUG options and stderr filter.  Thanks to
    Piers Cawley for spotting the omission.

2.00-rc2 2000-11-14

  - Added the 'prev' and 'next' methods to Template::Iterator and
    Template::Plugin::DBI::Iterator to return the previous and next
    items from the data set.

  - Added the 'sort' and 'nsort' virtual methods for hash arrays,
    thanks to a patch provided by Leon Brocard.

  - Various fixes to DBI plugin, configuration and test:- modified
    Makefile.PL to prompt for DBI DSN specific to user's DBD; changed
    DBI plugin to accept DBI attributes (e.g. ChopBlanks) as named
    parameters to connect method; fixed t/dbi.t to not munge 'user'
    variable in final test; added 'ChopBlanks' attributes to satisfy
    tests under certain DBD's (e.g.  Pg).  Thanks to Jonas Liljegren and
    Chris Nandor for their efforts in finding, testing and fixing the
    problems.

  - Modified the XML::DOM plugin to work with XML::DOM version 1.27
    which now uses blessed array references instead of hashes as the
    underlying data types.  Changed Makefile.PL and t/dom.t to require
    version 1.27 or later.

  - Changed the Template::Iterator module to *NOT* automatically expand
    the contents of blessed ARRAY objects to construct the iteration data
    set.  The previous behaviour caused problems with modules such as
    XML::DOM where a single object passed to the iterator constructor
    would be expanded into a list of the member data, rather than being
    treated as a single item list containing that one object.  A blessed
    ARRAY reference can now provide the as_list() method which the
    iterator constructor will call to return list data.

  - Fixed a bug in Template::Provider to ensure that template metadata
    (e.g. name, modtime, etc.) is written to compiled template files.
    Thanks to Steven Hetland for reporting the problem.

  - Changed the Template::Directive::template() generator method to
    raise an error if a context reference isn't passed to a template
    subroutine as the first argument.

  - Fixed t/autoformat.t to use locale dependant numerical formatting.
    Note that versions of Perl prior to 5.6.0 still have problems and
    will cause t/autoform.t tests 23 and 25 to fail under locales that
    use a decimal separator other than '.'.  The Makefile.PL will issue
    a warning in such cases.  Thanks to Jonas Liljegren for reporting
    the problem.

  - Applied a patch from Leon Brocard which corrects the behaviour of
    the URL plugin to join parameters with '&amp;' instead of '&'.

  - Fixed a bug in the AUTOLOAD method of the Template::Plugin base
    class which caused warnings about not finding _DELEGATE pseudo-hash
    method under Perl 5.6.0.

  - Various minor documentation fixes, thanks to Henrik Edlund and Leon
    Brocard.

2.00-rc1 2000-11-01

  - Added the push(), pop(), unshift() and shift() virtual list methods
    and fixed the parser to allow empty lists to be created (also fixed
    the parser to prevent warnings being raised by empty hashes).
    Updated test scripts and documentation to include examples.  Thanks
    to Stas Beckman for raising the issue.

  - Incorporated the DBI plugin module, written by Simon Matthews.  This
    features a major reorganisation of the code, fixes a few bugs, removes
    some lava flow, and has improved documentation and test script.

  - Updated the Makefile.PL to prompt for DBI test parameters, check for
    external modules (and in particular, versions which may cause problems)
    and various other niceties.  Also updated the README and TODO files.

  - Rewrote the XML::DOM plugin, fixing the memory leakage problems and
    adding the toTemplate() method and friends, as provided by Simon
    Matthews.  Note that it's quite easy to send Perl into a deep
    recursive loop via the childrenToTemplate() and allChildrenToTemplate()
    methods due to a misfeature added by abw.  This will be fixed in a
    future release and may result in behavioural changes to the
    *children* methods,  so don't rely on them too heavily for now.

  - Incorporated the Dumper plugin from Simon Matthews which interfaces to
    the Data::Dumper module.

  - Fixed a bug in the Datafile plugin which was causing the last data field
    to be ignored.  Credit due (yet again!) to Simon Matthews for finding
    the missing chomp().

  - Fixed a bug in Template::Directive which was generating a 'Useless use
    of scalar ref constructor in void context...' for empty BLOCK
    definitions.

  - Added the Wrap and Autoformat plugins which interface to Text::Wrap
    and Text::Autoformat respectively.  Thanks to Robert McArthur for the
    original Autoformat plugin code.

  - Added the XML::XPath plugin, test script and documentation.

  - Fixed a bug in the Template::Service module which was using any
    non-word characters to delimit lists of PRE/POST_PROCESS files.
    A value such as 'config, header.html' would be interpreted as
    [ 'config', 'header', 'html' ].  It now uses the DELIMITER value
    which is ':' by default, e.g. PRE_PROCESS => 'config:header.html'
    is interpreted as [ 'config', 'header.html' ].

  - Fixed a bug in the parser grammar which was failing to correctly
    identify compound variables that contained two or more consecutive
    numbers.  For example, the variable [% pi.3.14 %] was being interpreted
    as 'pi' . '3.14', instead of 'pi' . '3' . '14'.

  - Further modified parser to accept single quoted BLOCK names that would
    otherwise choke on 'illegal' characters.  e.g. [% BLOCK 'foo bar' %]

  - Changed the Template::Context::template() method to always throw an
    exception when a template can't be found instead of simply setting
    an internal error string.  Modified other Template::Context and
    Template::Service methods to expect this behaviour and act
    accordingly.  The visible impact of this is that the Template
    error() method will now always return an exception object.
    Previously there were certain cases where a plain error string would
    have been returned.

  - Change the ROOT_OPS, SCALAR_OPS, HASH_OPS and LIST_OPS virtual
    method tables in Template::Stash to incorporate any existing defined
    values.  Previously, you had to 'use Template::Stash' before
    defining any new virtual methods to prevent them being overwritten
    when Template::Stash was subsequently loaded.  Thanks to Chris
    Nandor for identifying the problem and suggesting a fix.

  - Changed BREAK directive to LAST to keep it in line with Perl (don't
    know why I originally chose 'BREAK' - must have had my C head on at
    the time).  BREAK is still supported as an alias for LAST.

  - Renamed the Template::Iterator number() method to count(), although
    number() is still supported for backwards compatability.  The DBI
    plugin used count() instead of number() (an oversight, I think) but I
    decided that count() was the better name (shorter and more obvious).
    Also changed internal Template::Iterator counter variables to UPPER
    CASE to allow AUTOLOAD to be more easily reused by derived iterators
    such as the one for the DBI plugin.

  - The Template::Plugin module is now derived from Template::Base.  The
    only significant ramification of this is that plugins should now
    call the error() method on failure in preference to fail().  The
    fail() method is still supported and delegates on to error(), but it
    raises a deprecation warning.

  - Fixed a bug in the Table plugin which caused an "undefined variable..."
    warning to be emitted when an empty list was provided.

  - Renamed 'evalperl' filter to 'perl', something that previously
    couldn't be done (before ANYCASE) due to 'perl' clashing with 'PERL'
    reserved word.  'evalperl' is still provided for backwards
    compatability.  Also added 'evaltt' as an alias for the 'eval'
    filter and 'file' as an alias for 'redirect' (which I claimed to
    have done back in beta 3 but obviously hadn't).

  - Fixed a bug in the perl/evalperl filter which was causing a stash
    reference to be bound in a closure that could later become
    invalidated.  This could lead to variables not getting/setting their
    correct values in subsequent calls to the same filter.

  - Documented the problem identified by Chris Winters where an IF
    used as a side-effect to an implied SET directive doesn't behave as
    expected.  A directive of the form  [% foo = 'bar' IF condition %]
    should be written explicitly as [% SET foo = 'bar' IF condition %]

  - Documented the 32k size limit (or typically less) for templates when
    the INTERPOLATE option is set.

2.00 2000-09-14 - beta 5

  - Added define_filter($name, \&filter, $is_dynamic) method to
    Template::Context to allow additional filters to be defined at any
    time.  Arguments are as per the FILTERS configuration option.
    These filters persist for the lifetime of the processor.

  - Changed the Template::Context filter() method to accept a code
    reference as the filter name and use it as the filter sub.  This
    allows filters to be bound to template variables which are then
    used as:

      [% FILTER $myfilter %]

    There is one catch, however.  TT will automatically call a subroutine
    bound to a variable when evaluated.  Thus you must wrap your filter
    sub in another sub: $stash->set('foo', sub { \&myfilter }); or bless
    it into some class (any class) to fool TT into thinking it's not a
    subroutine ref: $stash->set('bar', bless \&myfilter, 'any_old_name');

  - Updated documentation for FILTER directive and FILTERS option to
    reflect the above changes.

  - Fixed Template::Document to run cleanly with taint checking enabled.
    Unfortunately, this has been achieved by blindly untainting the
    generated template Perl code before calling eval().  Given that
    we're reading template source from external files, I don't think
    there's any way to do reliable taint check anyway.  But thankfully
    we can trust the parser to generate "safe" code unless EVAL_PERL is
    enabled in which case all bets are off anyway.

  - Updated XML::DOM plugin to include changes made by Thierry-Michel
    Barral to accept configuration options for XML::Parser.

  - Fixed a bug in the Table plugin which caused the first item to be
    repeated n times when n items was less than a specified number of
    columns.  Thanks to Andrew Williams for finding and fixing this
    bug.

  - The Template::Tutorial document really is included in the
    distribution this time.  Honest.

2.00 2000-09-12 - beta 4

  - Added the PROCESS config option which allows a template or templates
    to be specified which is/are processed instead of the template
    passed as an argument to the Template process() method.  The
    original template is available as the 'template' variable and can be
    processed by calling INCLUDE or PROCESS as [% INCLUDE $template %].

  - Changed what was the CASE option to now be enabled by default, and
    then changed the name of the option to ANYCASE to make it more
    obvious as to what it did.  You must now specify directive keywords
    (INCLUDE, FOREACH, IF, etc) in UPPER CASE only, or enable the
    ANYCASE option to revert to the previous behaviour of recognising
    keywords in any case.  With the increase in reserved words in
    version 2, there is more chance of collision with variable names.
    It's a real pain not being able to have a variable called 'next', an
    exception called 'perl', etc., because there's a reserved word of
    the same name.  Thus, keywords are now UPPER CASE only by default,
    neatly side-stepping the problem.

  - Changed the PERL directive so that output is generated by calling
    print() instead of using the final value in the block.  Implemented
    by tying STDOUT to an output buffer based on a patch sent in by
    Chuck Adams.

      new:                      old:
        [% PERL %]                [% PERL %]
           print "foo\n";            my $output = "foo\n";
           ...                       ...
           print "bar\n";            $output .= "bar\n";
        [% END %]			   $output;
                                  [% END %]

  - The IMPORT directive and magical IMPORT variable have been replaced
    with a general purpose virtual hash method, import().

      [% hash1.import(hash2) %]   # was "hash1.IMPORT = hash2"
      [% import(hash1) %]	        # was "IMPORT hash1" or "IMPORT = hash1"

  - Modified the Template::Filters provider to examine the FILTERS
    package hash reference (changed name from STD_FILTERS) each time a
    filter is requested rather than copying them at construction time.
    This allows new filters to be added on-the-fly.  See t/filter.t for
    examples and Template::Filters for more info.

  - Added the 'nsort' list method which sorts items using a numerical
    value sort rather than an alpha sort.

      [% data = [ 1, 5, 10, 11 ] %]
      [% data.sort.join(', ')  %]     # 1, 10, 11, 5
      [% data.nsort.join(', ') %]     # 1, 5, 10, 11

  - Added 'div' operator to provider integer division (e.g. 'a div b' =>
    'int(a / b)' and 'mod' which is identical to '%' but added for backwards
    compatibility with V1.

  - Changed the (undocumented) FORNEXT directive to NEXT and documented it.

  - Fixed a bug in the persistent caching mechanism in Template::Provider
    which was failing to write compiled template files for source templates
    specifed in the form [% INCLUDE foo/bar %].  Intermediate directories
    (like 'foo' in this example) weren't being created and the disk write
    was failing.  Thanks to Simon Matthews for identifying this problem.

  - Fixed an obscure bug in the Template::Stash which was ignoring the
    last element in a compound variable when followed by an empty
    argument list.  e.g. [% cgi.param() %] would be treated as [% cgi %].
    Also fixed the DEBUG option so that undefined variables cause 'undef'
    exceptions to be raised.  Thanks to Jonas Liljegren for reporting the
    problems.

  - Added the reference operator, '\' which allows a "reference" to
    another variable to be taken.  The implementation creates a closure
    around the referenced variable which, when called, will return the
    actual variable value.  It is really a form of lazy evaluation, rather
    than genuine reference taking, but it looks and smells almost the same.
    Primarily, it is useful for allowing sub-routine references to be
    passed to another sub-routine.  This is currently undocumented
    because I'm not sure about the validity of adding it, but see t/refs.t
    for examples for now.

  - Changed parser to automatically unescape any escaped characters in
    double quoted strings except for \n and \$.  This permits strings to
    be constructed that include tag characters.  e.g.

      [% directive = "[\% INSERT thing %\]" %]

  - Fixed a bug in the use of the 'component' variable when the current
    component is a sub-routine rather than a Template::Document.

  - Added the '--define var=val' option to tpage to allow template
    variables to be defined from the command line.  Added support to
    ttree for various new Template configuration options.

  - Added $Template::Test::PRESERVE package variable which can be set to
    prevent newlines in test output from being automatically mangled to
    literal '\n'.

  - Completed and corrected all knows bugs in the documentation which
    now weighs in at around 100 pages for the Template.pm module alone.
    The POD documentation should now be installed by default.  The
    Template::Tutorial document is once again included in the
    distribution.

2.00 2000-08-10 - beta 3

  - Added the WRAPPER directive to include another template, passing the
    enclosing block as the 'content' variable.  e.g.

    somefile:                    mytable:
      [% WRAPPER mytable %]        <table>
         blah blah blah            [% content %]
      [% END %]                    </table>

    This is equivalent to:

      [% content = BLOCK %]
         blah blah blah
      [% END %]
      [% INCLUDE mytable %]

  - Added the [% INSERT file %] directive to insert the contents of a disk
    file without processing any of the content.  Looks for the file in the
    INCLUDE_PATH and honours the ABSOLUTE and RELATIVE flags.  Added the
    insert($file) method to Template::Context which calls the new
    load($file) method in Template::Provider which loads the file text
    without compiling it.

  - Added the DEFAULT configuration option which allows you to specify a
    default template which should be used whenever a named template
    cannot be found.  This is ignored for templates specified with absolute
    or relative filenames, or as references to an input filehandle or text.

  - Added a FORNEXT directive to step on to the next iteration of a
    FOREACH loop, as suggested/requested by Jo Ellen Wisnosky.  I chose
    FORNEXT rather than simply NEXT because 'next' is a very common
    variable name but I'm open to better suggestions.  Perhaps CASE
    should be set by default to prevent variable conflict?  This might
    change.

  - Reorganised the Template::Filters modules and changed the calling
    convention for requesting filters via the fetch() method.  This now
    expects a reference to the calling Template::Context object as the
    third parameter (after filter name and reference to a list of arguments).
    Static filter sub-routines are returned as before and the context has
    no effect.  Dynamic filter factories (denoted by a $is_dynamic flag
    in the FILTER_FACTORY table) are called to create a filter sub-routine
    (closure) for each request.  The context is now passed as the first
    parameter, followed by the expansion of any arguments.  Filter
    factories should return a sub-routine or (undef, $error) on error.

  - Added several new filters:
    - 'stderr' prints the output to STDERR (i.e. for generating output
      in the Apache logfile, for example).  e.g. [% message | stderr %]

    - 'file' is the equivalent of the version 1 redirect() filter which
      writes the output to a new file, relative to OUTPUT_PATH.  Throws
      a 'file' exception if OUTPUT_PATH is not set.  There should perhaps
      be some other way to disable this without relying on OUTPUT_PATH.

    - 'eval' evaluates the input as a template and processes it.  Proposed
      by Simon Matthews for times when you might be returning templates
      fragments from a database, for example.  e.g. [% dirtext | eval %]

    - 'evalperl' evaluate the input as Perl code, as suggested by Jonas
      Liligren. Requires the EVAL_PERL option to be set and will throw a
      'perl' error if not (see later item).  e.g. [% perlcode | evalperl %]

  - Fixed a bug in Template::Provider which was mangling the metadata items
    for the template name and modification time.  The [% template.name %]
    and [% template.modtime %] variables now work as expected.

  - Added 'component' variable, similar to 'template', but which references
    the current template component file or block, rather than the top-level
    template.  Of course, these may be one and the same if you're not nesting
    any templates.

  - Template::Provider now reports errors raised when re-compiling
    modified templates rather than ignoring them, thanks to a patch from
    Perrin Harkins.

  - Fixed Template::Context to recognise the RECURSION option once more,
    thanks to a patch from Rafael Kitover.

  - Overloaded "" stringification of Template::Exception to call as_string(),
    again thanks to Rafael.  In a catch block you can now simply say
    [% error %] as well as the more explicit  [% error.type %] and/or
    [% error.info %].

  - Changed Template module (via Template::Service) to return the
    exception raised rather than a pre-stringified form.  This allows
    you to test the type() and/or info() if you want, or just print it
    and rely on the automatic stringification mentioned above to format
    it as expected.  Note that the top-level process($file) method
    returns a string rather than an exception if $file can't be found.
    This is a bug, or a possible "gotcha" at the very least, and should
    get fixed some time soon.  For now, test that the error is a
    reference before attempting to call info() or type().

  - Fixed a bug preventing literal newlines from being used in strings.
    Thanks to Simon Matthews for bringing it to my attention by calling
    my hotel room at the Perl Conference and saying "Hello?  Is that the
    Template Toolkit Helpdesk?  I have a bug to report..."  :-)
    (I fixed it on his laptop a few minutes later - good service, eh?)

  - Changed Template::Parser to not compile PERL or RAWPERL blocks if
    EVAL_PERL is not set.  Previously they were compiled but switched out
    at runtime.  This was erroneous as rogue BEGIN { } blocks could still
    be executed, as noted by Randal Schwartz.  Any PERL or RAWPERL blocks
    encountered when EVAL_PERL is disabled will now cause a 'perl' exception
    to be thrown.

  - Added a define_block($name, $block) option to Template::Context to
    add a definition to the local BLOCKS cache.  $block can be a reference
    to a template sub-routine or Template::Document object or template
    text which is first compiled.

  - Any other errors thrown in a PERL blocks (assuming EVAL_PERL set)
    are now left unchanged.  Previously, these were converted to 'perl'
    exceptions which prevented exceptions of other kinds being throw
    from within Perl code.

  - Applied a patch from Chris Dean to fix a bug in the list 'sort'
    method which was converting a single element list into a hash.  The
    sort now does nothing unless there's > 1 elements in the list.

  - Changed Template::Stash set() method to append the assigned value to
    the end of any arguments specified, rather than prepending it to the
    front.  e.g. The foo() method called by [% myobj.foo(x, y) = z %] now
    receives arguments as foo(x, y, z) instead of foo(z, x, y).

  - Changed Template::Base::error() to accept a reference (e.g. exception)
    as the first parameter.  In this case, no attempt is made to
    concatenate (and thereby stringify) the arguments.

  - Added a direct stash() accessor method to Template::Context rather
    than relying on the slower AUTOLOAD method.

  - Added an iterator() method to Template::Config to require
    Template::Iterator and instantiate an iterator, and changed
    generated code for FOREACH to call this factory method.  This fixes
    a bug with pre-compiled (i.e persistent) templates which were
    failing if Template::Iterator wasn't already loaded.  Thanks to Doug
    Steinwand, Rafael Kitover and Jonas Lilegren who all identified the
    problem and hounded me until I fixed it.  :-)

  - Fixed a problem with persistent templates not being reloaded due to
    the %INC hash.  This caused 1 to be returned from require() instead
    of the compiled template.

  - Added ABSOLUTE and RELATIVE options to tpage by default.

  - Applied various documentation and test patches from Leon Brocard.
    Fixed docs to quote dotted exception types to prevent string
    concatenation, as noted by Randal Schwartz.  Generally added a
    whole lot more documentation.

2.00 2000-07-14 - beta 2

  - Added COMPILE_DIR option.  This allows you to specify a separate
    directory in which compiled templates should be written.  The COMPILE_DIR
    is used as a root directory and each of the INCLUDE_PATH elements is
    created below that point.  e.g. the following options

      COMPILE_DIR  => '/tmp/ttcache',
      INCLUDE_PATH => '/user/foo/bar:/usr/share/templates',

    would create the following cache directories:

      /tmp/ttcache/user/foo/bar
      /tmp/ttcache/usr/share/templates

    Templates originating from source files in the INCLUDE_PATH are thus
    written in their compiled form (i.e. Perl) to the relevant COMPILE_DIR
    directory.  The COMPILE_EXT option may also be used in conjunction with
    COMPILE_DIR to append a filename extension to all compiled files.

  - Fixed memory leaks caused by the huge circular reference that is the
    Template::Provider's linked list of cache slots.  Added a DESTROY method
    which walks the list and explicitly breaks the chains (i.e. the NEXT/PREV
    links), thus allowing the compiled Template::Document objects to be
    correctly destroyed and their memory repooled.  Thanks to Perrin Harkins
    for spotting the problem.

  - Added a work-around in Template::Stash _dotop() to the problem of the
    CGI module denying membership of the UNIVERSAL class on subsequent calls
    to UNIVERSAL::isa($cgi, 'UNIVERSAL').  It works correctly the first time,
    but returns false for all subsequent calls.  Changed this generic
    "is-an-object" test to UNIVERSAL::can($cgi, 'can') on the suggestion
    of Drew Taylor who identified the problem.

  - Added t/macro.t to test MACRO directive, t/compile4.t and t/compile5.t
    to test the COMPILE_DIR option.

  - More complete documentation, but not yet fully complete.

2.00 2000-07-10 - beta 1

  - Template::Context include()/process() now works with raw CODE refs.

  - Template.pm now prefixes OUTPUT with the OUTPUT_PATH when OUTPUT
    is a file name.

  - Cleaned up Template::Iterator.  Now derived from Template::Base.
    Removed ACTION and ORDER now that they are supported as list pseudo
    methods in the Stash LIST_OPS.

  - Fixed bug in Provider preventing updated files from being automatically
    reloaded.  Thanks to Perrin Harkins who provided the patch.

  - Fixed bug in Template::Plugin::Datafile which was preventing a comment
    from being placed on the first line of the file.

  - Fixed bug in parse grammer preventing commas in a META list

  - Added cache persistence by writing real Perl to file (rather than
    the previous Data::Dumper dump of the opcode tree).  Had to
    re-organise a bunch of code around the parser/provider/document.
    Activated by COMPILE_EXT configuration item.

  - Added a work-around in Template::Stash to the problem of CGI disclaiming
    membership of the UNIVERSAL class after the first method call.

  - Added AUTO_RESET option which is enabled by default.  Disable this
    (AUTO_RESET => 0) for block persistence across service invocations.

  - Fixed \@ quoting (and others) in Directive thanks to Perrin Harkins
    who reported the bug and Chuck Adams who provided a patch.

  - Added Date plugin and test, as provided by Thierry-Michel Barral.

  - Integrated changes to Template::Test from version 1.07 and beyond.  Now
    supports -- process -- option in expect, mainly for use of t/date.t et al.

  - Integrated new upper and lower filters from 1.08, and '|' alias for FILTER
    from 1.07.

  - Added new directive.t test to test chomping and comments.

  - BLOCKS can now be defined as template text which gets automatically
    compiled into a Template::Document object.

  - Integrated XML plugins and tests from version 1.07

  - Fixed TRIM option to work with all BLOCKs and templates.  Moved TRIMing
    operation into context process() and include() methods.  Also changed
    service to call $context->process($template) rather than call the sub/
    doc itself, thus ensuring that the output can get TRIMmed.

  - Updated Template::Plugin.pm

  - Added '--define' option to ttree.

  - Integrated various plugins and filters from v1.07

  - Moved Template::Utils::output into Template.pm?) and got rid of
    Template::Utils altogether.

  - Fixed bug in Context filter() provider method which wasn't caching
    filters with args.

  - [% CASE DEFAULT %] is now an alias for [% CASE %] (the default case),
    in consistency with [% CATCH DEFAULT %] / [% CATCH %]

2.00 - alpha 1

  - first public alpha release of Version 2.00

    #                           VERSION 2.00
    # The following list outlines the major differences between version 1.*
    # and version 2.00 of the Template Toolkit.

  [New Language Features]
  - New SWITCH / CASE statement.  SWITCH takes an expression, CASE takes
    a value or list of values to match.  CASE may also be left blank or
    written as [% CASE default %] to specify a default match.  Only one
    CASE matches, there is no drop-through between CASE statements.

      [% SWITCH myvar %]
      [% CASE value1 %]
         ...
      [% CASE [ value2 value3 ] %]   # multiple values to match
         ...
      [% CASE myhash.keys %]         # ditto
         ...
      [% CASE %]                     # default, or [% CASE default %]
         ...
      [% END %]

  - New TRY / CATCH / FINAL construct for fully functional, nested
    exception handling.  The block following the TRY is executed and
    output if no exceptions are throw.  Otherwise, the relevant CATCH
    block is executed.  CATCH types are hierarchical (e.g 'foo' catches
    'foo.bar') or the CATCH type may be left blank or specified as [%
    CATCH default %] to provide a default handler.  The contents of a
    FINAL block, if specified, will be processed last of all, regardless
    of the result (except an uncaught exception which is throw upwards
    to any enclosing TRY block).

      [% TRY %]
         ...blah...blah...
         [% CALL somecode %]	  # may throw an exception
         ...etc...
         [% INCLUDE someblock %]    # may have a [% THROW ... %] directive
         ...and so on...
      [% CATCH file %]		  # catch system-generated 'file' exception
         ...
      [% CATCH DBI %]		  # catch 'DBI' or 'DBI.*'
         ...
      [% CATCH %]	                  # catch anything else
         ...
      [% FINAL %]		          # optional
         All done!
      [% END %]

  - New CLEAR directive to clear the current output buffer.  This is typically
    used in a CATCH block to clear the output of a failed TRY block.  Any output
    generated in a TRY block up to the point that an exception was thrown will
    be output by default.  The [% CLEAR %] directive in a catch block clears
    this output from the TRY block.

      [% TRY %]
         blah blah blah, this is the current output block
         [% THROW some.error 'Danger Will Robinson!' %]
         not reached...
      [% CATCH %]
         [% # at this point, the output block contains the 'blah blah...' line
            # up to the point where the THROW occured, but we don't want it
            CLEAR
         %]
         Here we can add some more text if we want...
      [% END %]

    In general, the CLEAR directive clears the current output from the
    template or enclosing block.

  - New META directive allowing you to define metadata items for your
    templates.  These are attached to the compiled template and wrapped
    up as a Template::Document object.  The 'template' variable is a
    reference to the current parent document and metadata items may be
    accessed directly.  Of particular note is the fact that the
    'template' variable is correctly defined for all PRE_PROCESS and
    POST_PROCESS headers.  Thus, your headers and footers can access
    items from the main template (e.g. title, author, section, keywords,
    flags, etc) and display them or act accordingly.

    mytemplate:
      [% META
         title     = 'This is a Test'
         author    = 'Andy Wardley'
         copyright = "2000, Andy Wardley"
      %]

      <h1>[% template.title %]</h1>
      blah blah

    header:   (a PRE_PROCESS template)
      <html>
      <head><title>[% template.title %]</title></head>
      <body>

    footer:  (a POST_PROCESS template)
      <hr>
      &copy; Copyright [% template.copyright or '2000, MyCompany' %]

  - New RAWPERL ... END block directive allows you to write raw Perl
    code which is integrated intact and unsullied into the destination
    template sub-routine.  The existing PERL ... END directive continues
    to be supported, offering runtime evaluation of a block which may
    contain other template directives, etc, which are first evaluated
    (e.g. PERL...END processes the block and filters the output into
    Perl evaluation at runtime).

  - New INSERT directive which inserts the contents of a file without
    processing it.

  - New WRAPPER directive which processes the following block into the
    'content' variable and then INCLUDEs the named file.

      [% WRAPPER table %]
         blah blah blah
      [% END %]

      [% BLOCK table %]
      <table>
      [% content %]
      </table>
      [% END %]

  - Comments now only extend to the end of the current line.

      [% # this is a comment
         a = 10
         # so is this
         b = 20
      %]

    Placing the '#' character immediately inside the directive will comment
    out the entire directive

      [%# entire directive
          is ignored
      %]

  - The TAGS directive can now be used to switch tag styles by name.
    Several new tag styles are defined (e.g. html, asp, php, mason).

      [% TAGS html %]
      <!-- INCLUDE header -->

  - The output from any directive or block can now be captured and assigned to
    a variable.

      [% htext = INCLUDE header %]
      [% btext = BLOCK %]
         blah blah
         [% x %] [% y %] [% z %]
      [% END %]

      # you can even assign the output of loops, conditions, etc.
      [% numbers = FOREACH n = [2, 3, 5, 7, 11, 13] %]
         blah blah [% n %]
      [% END %]

  - The handling of complex expressions has been improved, permitting
    basic directives to contain logical shortcut operators, etc.  All
    binary operators now have the same precedence rules as Perl.

      [% foo or bar %]             # GET foo, or bar if foo is false (0/undef)
      [% CALL func1 and func2 %]   # func2 only called if func1 returns true
      [% name = user.id or cgi.param('id') %].

  - A new "x ? y : z" operation is provided as a shorthand for
    "if x then y else z"

      [% foo = bar ? baz : qux %]

  - A leading '$' on a variable is now used to indicate pre-interpolation
    of that element.  This simplifies the syntax and makes it consistent
    with double-quoted string interpolation and text block interpolation
    via the INTERPOLATE flag.  If you've been relying on the version 1
    "feature" that ignores the leading '$' then you'll need to change your
    templates to remove the '$' characters (except where you really want
    them) or set the V1DOLLAR flag to 1 to revert to the version 1
    behaviour.  See the 'Gotchas' section below for more details.

      # version 1
      [% hash.${key} %]  [% hash.${complex.key} %]

      # version 2
      [% hash.$key %]    [% hash.${complex.key} %]

  - Various new pseudo-methods have been added for inspecting and manipulating
    data.  The full list now looks something like this:

        [% var.defined %]               # variable is defined
        [% var.length %]                # length of string
        [% var.split(delim, limit) %]   # split string as Perl does

        [% hash.keys %]                 # return list of hash keys
        [% hash.values %]               # ditto hash values
        [% hash.each %]                 # ditto keys and values
        [% hash.import(hash2) %]        # merge hash2 into hash

        [% list.size %]                 # number of items in list
        [% list.max %]                  # last item number (size - 1)
        [% list.first %]                # first item
        [% list.last %]                 # last item
        [% list.push(item) %]	      # add item to end
        [% list.pop %]		      # remove item from end
        [% list.unshift(item) %]	      # add item to front
        [% list.shift %]	              # remove item from front
        [% list.reverse %]              # return reversed order
        [% list.sort(field) %]          # return alpha sorted order
        [% list.nsort(field) %]         # return numerical sorted order
        [% list.join(joint) %]          # return items joined into single string

  [Configuration Options]
  - Template blocks may be pre-defined using the new BLOCKS option.  These
    may be specified as template text or as references to sub-routines or
    Template::Document objects.

      my $template = Template->new({
  	BLOCKS => {
  	    header => '<html><head><title>[% title %]</title></head><body>',
  	    footer => '</body></html>',
  	    funky  => sub { blah_blah($blah); return $some_text },
  	}
      });

  - Automatic error handling can be provided with the ERROR option.  This
    allows you to specify a single template or hash array of templates which
    should be used in the case of an uncaught exception being raised in the
    a template.  In other words, if something in one of your templates
    throws a 'dbi' error then you can define an ERROR template to catch
    this.  The original template output is discarded and the ERROR template
    processed in its place.  PRE_PROCESS and POST_PROCESS templates (e.g.
    header and footers) are left intact.  This provides a particularly
    useful high-level error handling abstraction where you simply create
    templates to handle particular exceptions and provide the mapping
    through the ERROR hash.

      my $template = Template->new({
  	ERROR => {
  	    dbi        => 'error/database.html',   # DBI error
  	    'user.pwd' => 'error/badpasswd.html',  # invalid user password
  	    user       => 'user/index.html',	   # general 'user' handler
  	    default    => 'error/error.html',      # default error template
  	}
      });

  - The INCLUDE_PATH is now fully dynamic and can be changed at any time.
    The new Template::Provider which manages the loading of template files
    will correctly adapt to chahges in the INCLUDE_PATH and act accordingly.

  - The LOAD_TEMPLATES option allows you to specify a list of one or more
    Template::Provider object which will take responsibility for loading
    templates.  Each provider can have it's own INCLUDE_PATH, caching
    options (e.g CACHE_SIZE) and so on.  You can sub-class the
    Template::Provider module to allow templates to be loaded from a
    database, for example, and then define your new provider in the
    LOAD_TEMPLATES list.  The providers are queried in order as a "Chain
    of Responsiblity".  Each may return a compiled template, raise an
    error, or decline to serve the template and pass control onto the
    next provider in line.

  - The CACHE_SIZE option defines a maximum number of templates that will
    be cached by the provider.  It is undefined by default, causing all
    templates to be cached.  A value of 0 disables caching altogether while
    a positive integer defines a maximum limit.  The cache (now built into
    Template::Provider) is much smarter and will automatically reload and
    compile modified source templates.

  - The Template::Provider cache can write compiled templates (e.g. Perl code)
    to disk to create a persistent cache.  The COMPILE_EXT may be used to
    specify a filename extension (e.g. '.ttc') which is used to create
    compiled template files.  These compiled template files
    can then be reloaded on subsequent invocations using via Perl's
    require() (which is about as fast as it can get).  The Template::Parser
    and Template::Grammar modules are loaded on demand, so if all templates
    have been pre-compiled then the modules don't get loaded at all.  This
    is a big win, given that Template::Grammar is the biggy.

  - The ABSOLUTE and RELATIVE options are now used to enable the loading of
    template files (via INCLUDE or PROCESS) that are specifies with absolute
    (e.g. /tmp/somefile) or relative (e.g. ../tmp/another) filenames.  Both
    are disabled by default.

  - The LOAD_PLUGINS option is similar to LOAD_TEMPLATES but allows you
    to specify one or more plugin providers.  These take responsibility
    for loading and instantiating plugins.  The Template::Plugins module
    is the default provider and multiplexes requests out to other
    Template::Plugin::* plugin modules.  Loading of plugins has been
    simplified and improved in general The PLUGINS option can be used to
    map plugin names to specific modules and PLUGIN_BASE can map plugins
    into particular namespaces.  The LOAD_PERL option can be used to
    load (almost) any regular Perl module and use it as a plugin.

  - The LOAD_FILTERS option is similar to LOAD_TEMPLATES and LOAD_PLUGINS,
    allowing one or more custom providers to be specified for providing
    filters.  The Template::Filters module is the default provider here.

  - The TOLERANT option can be used to tailor the behaviour of providers
    (e.g. Template::Provider, Template::Plugins, Template::Filters) when
    they encounter an error.  By default, providers are not TOLERANT (0)
    and will report all failures as errors.  When TOLERANT is set to 1,
    they will ignore errors and return STATUS_DECLINED to give the next
    provider a chance to deliver a valid resource.

  - The INTERPOLATE option is now automatically disabled within PERL and
    RAWPERL blocks to prevent Perl $variables from being interpreted as
    template variables.

      # INTERPOLATE = 1
      This $var will get interpolated...
      [% PERL %]
         # but these won't
         my $foo = 'some value';
         my $bar = 'another value';
         # etc...
      [% END %]
      now we're interpolating variables again, like $var

  - Added the TRIM option to automatically removed leading and trailing
    whitespace from the output of templates and BLOCKs.

  - The CASE option has now been obsoleted and replaces by the ANYCASE
    option.  See comments elsewhere in this document ('Gotchas' below and
    notes for 2.00 beta 4) for further details.

  [Templates Compiled to Perl Code]
    Templates are now compiled to Perl code, with credit and respect due
    to Doug Steinwand for providing an implementation around which the
    new parser was built.  This brings a number of important benefits:

  - Speed and Memory Efficiency

    Version 1 used a list of opcodes to represent directives and
    lower-level operations.  These were evaluated by the hideously
    contrived, and darkly sinister Template::Context::_evaluate()
    method.  In version 2, all templates are parsed and rebuilt as Perl
    code.  This is then evaluated and stored as a reference to a Perl
    sub-routine which can then be executed and re-executed significantly
    faster and with far less memory overhead.

  - Persistence.

    Once a template has been compiled to Perl code it can be saved to
    disk as a "compiled template" by defining the COMPILE_EXT option.
    This allows you to specify a filename extension (e.g. '.ttc') which
    is added to the template filename and used to create a new file
    containg the Perl code.  Next time you use the template, even if
    you've shut down your program/server/computer in the mean time, the
    compiled template is there in a file as Perl code and is simply
    require()d and executed.  It all happens significantly faster
    because there's no Template::Parser to run.  In fact, if all your
    templates are "compiled" on disk then the Template::Parser and
    Template::Grammar modules won't even be loaded, further reducing
    startup time and memory consumption (the grammar file, in particular
    is rather large).  The Template::Provider module handles the
    loading, caching and persistence of templates, and will examine file
    timestamps and re-compiled modified templates as required.

  - Flexibility.

    Because "compiled templates" are now nothing more than Perl
    sub-routines, you can use anyone or anything to generate them and
    run them all under the same roof.  Different parser back-ends can
    generate Perl code optimised for speed or functionality, for
    example.  Or different parsers can compile different template
    languages (PHP, ASP, Mason, roll-your-own, etc.) and run them
    alongside regular templates.  Or if you don't trust a parser, you
    can even write your own Perl code and have your templates execute as
    fast as the code you can write.

  [Other Enhancements and Internal Features]
  - Templates (i.e. sub-routines) now return their generated output,
    rather than sending it to $context->output().  This speeds things
    up and makes the code simpler, as well as allowing greater
    flexibility in how template sub-routines can work.

  - Exceptions are now raised via Perl's die() and caught by an
    enclosing eval { } block.  Again, this simplifies the code generated
    and improves runtime efficiency.  The [% RETURN %] and [% STOP %]
    directives are now implemented as special case exceptions which are
    caught in the appropriate place and handled accordingly.

  - Local named BLOCK definitions are better behaved and don't permanently
    mask any real files.  BLOCK definitions remain local to the template in
    which they're defined, although they can be accessed from templates
    INCLUDEd or PROCESSed from within.  The PROCESS directive will export
    defined BLOCKs to the caller (as with variables) whereas INCLUDE will
    keep them "private".

  - The Template::Stash object now encapsulates all the magical variable
    resolution code.  Both simple and compound variables can be accessed
    or updated using the get() and set() methods, with all variable binding
    magic happening automatically.

  - The Template::Context object is now greatly simplified.  This acts
    as a general interface to the Template Toolkit functionality, being
    a collection of the various other modules that actually implement
    the functionality (e.g. Template::Stash, Template::Provider,
    Template::Document, Template::Plugins, etc.)

  - The Template::Provider object provides a general facility for
    retrieving templates from disk (or other source), and if necessary
    compiling via a call to a Template::Parser helper object.  Multiple
    Template::Provider objects may be chained together, each with their
    own caching options, and so on.

  - The Template::Parser object now compiles template text into Perl
    code and then evaluates it into a sub-routine reference using Perl's
    eval().  This is then wrapped up into a Template::Document object,
    including any metadata items and/or additional named BLOCKs defined
    in the input template.

  - The Template::Document object is a thin wrapper around a compiled
    template sub-routine.  It provides a process() method for processing
    the template and a blocks() method for returning a reference to the
    hash array of any additional named BLOCKs defined in the original
    template text.  An AUTOLOAD method returns values of metadata items,
    allowing a Template::Document reference to be used as the 'template'
    variable.

  - The Template::Service module provides a high-level service for
    processing templates, allowing PRE_PROCESS and POST_PROCESS templates
    to be specified along with an ERROR handling hash.

  - The Template::Base module defines a common base class for many of
    the toolkit modules.  It implements shared functionality such as a
    constructor, error reporting and handling, etc.  Modules are now
    much easier to sub-class, all using separate new() and _init()
    methods.

  - The Template::Config module provides methods for loading and
    instantiating different Template Toolkit modules.  Using this
    factory-based approach makes it far easier to change the default
    object class for a specific part of the toolkit.  e.g.

        use Template;
        use Template::Config;

        $Template::Config::PARSER = 'MyOrg::Template::MyParser';

        # $tt object will create and use a MyOrg::Template::MyParser
        # object as PARSER
        my $tt = Template->new({ ... })

  - The Template::Test module has been enhanced to make it easier to test
    more advanced TT features.  You can now define multiple TT processors
    and switch between them for different test with the '-- use name --'
    directive.  Also added the '-- process --' directive which can be
    added after '-- expect --' to hav the expected output processed by
    TT before comparison.

  - The Template module remains, as it ever was, a simple front-end to
    the Template Toolkit.  This creates a single Template::Service to
    which it delegates control for processing templates.  Output is
    returned according to the OUTPUT options specified for the module
    and/or any output option passed explicitly to the process() method.

  [New Filters]
  - 'upper' and 'lower' filters perform case folding of text.

  - 'eval' can be used to evaluate Template Toolkit directives at runtime.

  - 'perl' evaluates Perl code if (and only if) the EVAL_PERL flag is set.

  - 'stderr' is a simple filter to STDERR.

  - 'file' is a new alias for the 'redirect' filter.  The OUTPUT_PATH option
    must be set.

  [New Plugins]
  - The DBI plugin is now distributed with the Template Toolkit.

  - The Date plugin formats dates and times via the POSIX strftime() sub.

  - The Iterator plugin provides access to the Template::Iterator module.

  - The Dumper plugin provides an interface to the Data::Dumper module.

  - The Wrap and Autoformat plugins interface to the Text::Wrap and
    Text::Autoformat modules respectively.

  - The XML::DOM and XML::XPath plugins provide interfaces to the relevant
    XML modules.

  [Utility Scripts]
  - Added the '--define var=val' option to ttree.

  [Gotchas]
    Things that have changed between version 1 and 2 that might catch you
    out.

  - Bare CATCH blocks are no longer permitted and must be explicitly
    scoped with a matching TRY.  In most cases, this simply means adding
    a [% TRY %] to the start of any templates that define CATCH blocks,
    and ensuring that the CATCH blocks are moved to the end of the file
    (or relevant place).

         # version 1 - no longer supported
         blah blah blah...some error occurs

         [% CATCH some_kind_of_error %]
            handler template...
         [% END %]

         # version 2
         [% TRY %]
         blah blah blah...some error occurs...

         [% CATCH some_kind_of_error %]
            handler template...
         [% END %]

    Also be aware that this may change the expected output in case of
    errors.  By default, all output in the TRY block up to the point of
    error will be returned, with the relevant catch block, and then and
    further template output appended.  You can use [% CLEAR %] within a
    CATCH block to clear the output from the TRY block, if you prefer.
    TRY blocks can be nested indefinately.

  - The ERROR directive is no longer supported.  It was very ill-defined
    anyway and serves no purpose that can't be acheived by defining
    custom filters, error handlers bound to template variables, or
    whatever.  I haven't implemented any special error or logging
    facilities, other than the general purpose exception handling, but
    welcome any thoughts on what or if anything else is needed.

  - The ERROR option is also different.  It could previously be used
    to specify an error handling sub-routine, but is no longer required
    (see previous point).  The ERROR option in version 2 is used to
    define a map of error types to template names for automatic
    redirection for error handling.

  - The current exception caught in a catch block is now aliased to the
    variable 'error' rather than 'e'.  This is much more logical, IMHO,
    and was only prevented previously by 'error' being a reserved word.
    Note that 'e' is still defined, in addition to 'error'.  This may be
    deprecated at some point in the future.

  - The use of a leading '$' on variables is no longer optional, and
    should only be used to explicitly to indicate interpolatation of a
    variable name.  Most of the time you *don't* want to do this, so
    leave the '$' off.  This represent a slight shift away from the
    (optional) Perlness of the language, but I think it's a necessary
    step to improve the clarity and consistency of the language.

      As previously discussed on the mailing list, in interpolated text
    (i.e. a "double quoted" string or regular template text with
    INTERPOLATE set), both '$foo' or '${foo}' are interpolated as the
    value of the variable 'foo'.  This is good because it is a de-facto
    standard, consistent with Perl, shell, etc.  But inside a directive,
    [% $foo %] and [% ${foo} %] mean different things, the first being
    equivalent to [% foo %] or [% GET foo %] (the leading '$' is
    ignored) but the second actually fetching a variable whose name is
    stored in the variable 'foo'.  In other words, '${foo}' interpolates
    to the value of foo ('bar', say) and then this is used as the
    parameter to GET (which itself is optional).  Thus, in this case, [%
    ${foo} %] is [% GET ${foo} %] is [% GET bar %].

    This makes more sense if you look at the common example of
    accesing an entry from a hash array using the value of an variable
    as the key (e.g. $hash->{ $key }).  In version 1, the leading '$' on
    variables is ignored, meaning that the following are NOT identical.

        # version 1
        [% hash.$key   %]     # ERROR - '$' ignored => [% hash.key %]
        [% hash.${key} %]     # OK - '$key' is interpolated first

    It gets more confusing if you excercise your right to add optional
    leading '$'s in other places (which is one reason why I've always
    suggested against their use).

        # version 1 - same as above
        [% $hash.$key   %]
        [% $hash.${key} %]

    In particular, that last example should demonstrate the
    inconsistency.  Unlike interpolated text, '$...' and '${...}' are
    not treated the same and '$hash' is not interpolate while '${key}'
    is.  The only consistent solution I can see to this is to make both
    '$xxx' and '${xxx}' indicate interpolation in all cases, so that's
    what I've done.  In version 2, the syntax becomes a lot clearer and
    aligns more closely to a markup language than a programming
    language.  I think this is a Good Thing, but let me know what you
    think...

    Here's the Version 2 summary, assuming INTERPOLATE is set.

        # version 2
        my name is $name
        my name is $user.name
        my name is ${user.name}

        [% GET name %]                 [% name %]
        [% GET user.name %]            [% user.name %]
        [% GET people.fred %]          [% people.fred %]
        [% GET people.$name        %]  [% people.$name %]
        [% GET people.${user.name} %]  [% people.${user.name} %]

        [% INCLUDE header
           title = "Home Page for $name"
        %]
        [% INCLUDE header
           title = "Home Page for $user.name"
        %]
        [% INCLUDE header
           title = "Home Page for ${user.name}"
        %]

  - Changed default TAG_STYLE to only recognise [% ... %] and not the MetaText
    compatability %% ... %% style.  Set TAG_STYLE => 'template1' to accept both,
    or 'metatext' for just %% ... %%

  - Changed how error/return values should be returned from user code.
    All errors should be thrown via one of the following:

      die $error_msg;
      die (Template::Exception->new($type, $info));
      $context->throw($msg);
      $context->throw($type, $info);
      $context->throw($exception);

  - USERDIR and USERBLOCK are not supported (they were experimental and
    undocumented, anyway)

  - $Template::Directive::While::MAXITER is now
    $Template::Directive::WHILE_MAX and may change again.

  - into() filter is now obsolete.  You can now simply assign the output of
    another directive or block to a variable.

      [% x = INCLUDE foo %]
      [% y = BLOCK %]
         blah blah blah
      [% END %]

  - The CASE option has been removed and replaced with the ANYCASE option
    which is the logical opposite.  Directive keywords should now be UPPER
    CASE by default and the ANYCASE option can be enabled to revert to
    the previous behaviour of accept keywords in any case.

  - The IMPORT directive and magical variable have been removed and
    replaced by a general purpose virtual hash method, import().
    [% IMPORT myhash %] should now be written [% import(myhash) %]
    and [% myhash.IMPORT = another.hash %] should be written as
    [% myhash.import(another.hash) %]
