0.56, November 7, 2006:

• In build process, fixed dependency check for prerequisite Algorithm::Diff (#7340).
• Produce correct output when a diff chunk is precisely '0' (#6756).
• Install the htmldiff tool into your bin directory on make install (#7341).
• Fixed some bugs where html_word_diff gave the wrong flag for a chunk (e.g. ['+', 'b', 'b c']).

0.55, April 27, 2004:

• Fixed a problem where some "same" chunks were considered "different." This occured if you had container tags that used uppercase letters.
• First element of result always contained a 'different' chunk between undef values. It's now suppressed.

0.54, June 15, 2003:

• Following XTHML spec, added all the "single" (unclosable) tags, such as IMG, BASE, LINK, etc. to the list of such tags used by the module.
• Converted this list into an exposed package variable, so that push @HTML::Diff::UNBALANCED_TAGS, $new_tag_name allows you to modify the list of "single" tags.

0.52, April 17, 2003:

• Switched to Makefile.PL, thereby fixing broken tests.

v0.51, April 16, 2003:

• Added htmldiff script contributed by Maurice Aubrey.

v0.5, March 31, 2003 -- initial release
