* Added the even(), odd() and parity() methods to Template::Iterator to
  assist in making zebra tables.

  https://rt.cpan.org/Ticket/Display.html?id=46250

* Replaced a whole bunch of UNIVERSAL::isa() calls with blessed/isa

# Version 2.20_3 (2.21 candidate) - 20th May 2009
#------------------------------------------------------------------------

* Fixed the XS Stash to compile properly in threaded Perls.
  https://rt.cpan.org/Public/Bug/Display.html?id=46240

* Applied a patch to the XS Stash from Alexey A. Kiritchun to make the

  http://lists.tt2.org/pipermail/templates/2009-May/010803.html

#-----------------------------------------------------------------------
# Version 2.20_2 (2.21 candidate) - 17th May 2009
#------------------------------------------------------------------------

* 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
  and added the VIEWS option to pre-define views when the Template object
  is created.  Thanks to Timmy Chan for providing the groundwork on this.
  http://lists.tt2.org/pipermail/templates/2009-April/010689.html

* Retrospectively fixed the Changes for 2.20 to mention the ttree
  --encoding option.

* Applied a patch from Chisel Wright, changing uses of UNIVERSAL::can()
  to use blessed() and ->can().
  http://lists.tt2.org/pipermail/templates/2009-May/010790.html

* Fixed a memory leak in the XS Stash introduced in 2.20.
  Thanks to Breno G. de Oliveira for reporting the problem and helping to
  narrow it down.

#------------------------------------------------------------------------
# Version 2.20_1 (2.21 candidate) - 7th April 2009
#------------------------------------------------------------------------

* 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.
