2003-01-18   Sean M. Burke <sburke@cpan.org>

   Release 3.17 -- minor bugfix

   HTML::Element : Making as_HTML('',...) work just like
   as_HTML(undef,...).  Also fixing as_XML's docs to remove mention of
   an unimplemented feature (specifying what characters to escape).

2002-11-06   Sean M. Burke <sburke@cpan.org>

   Release 3.16 -- just fixing a doc typo.

2002-11-06   Sean M. Burke <sburke@cpan.org>

   Release 3.15 -- a few new features.

   Added the aliases "descendents" and "find" to HTML::Element.

   Added a new method "simplify_pres" to HTML::Element.

   Release 3.14 -- minor bugfix

   Just fixes a few problems in HTML::Element with the number_lists
   method.

2002-08-16   Sean M. Burke <sburke@cpan.org>

   Release 3.13 -- basically a bugfix version

   It turns out that 3.12 had a hideous HTML::TreeBuilder bug that
   made the whole thing damn near useless.  Fixed.
   Many many thanks to Michael Koehne for catching this!

   Wrote t/parse.t, to catch this sort of thing from happening again.

   Fixed a bug that would treat <td> outside any table context
   as <tr><table><td> instead of <table><tr><td>

2002-07-30   Sean M. Burke <sburke@cpan.org>

   Release 3.12

   Added as_trimmed_text method to HTML::Element, as described
   (prophesied?) in the fantabulous new book /Perl & LWP/.

   Bugfix: fixed unshift_content when given a LoL.  (_parent wasn't
   getting set right.)

   HTML::Element and HTML::TreeBuilder now enforce at least some
   minimal sanity on what can be in a tag name.  (Notably, no spaces,
   slashes, or control characters.)

   Semi-bugfix: $element->replace_with(...) can now take LoLs in its
   replacement list.

   Bumped HTML::Element version up to 3.12 (right from 3.09)

   Semi-bugfix: as_XML now doesn't use named entities in its return
   value -- it always uses numeric entities.

   Added behavior: new_frow_lol can now do clever things in list
   context.

   HTML::Tree -- added blurb for /Perl & LWP/

   HTML::TreeBuilder -- added blurb for /Perl & LWP/
   Also added a few tweaks to do better with XHTML parsing.
   Added guts() and disembowel() methods, for parsing document fragments.
