    [THINGS THAT MAY BREAK YOUR CODE OR TESTS]
    * Mark-Jason Dominus points out that the fix for as_html was not
      proper, and broken behavior should never be codified.  Fixed
      as_html so an empty string doesn't encode entites, instead of
      blaming the behavior on HTML::Entities.  (RT 18571)

3.22 	Sat Nov 11 21:23:22 CST 2006
    [THINGS THAT MAY BREAK YOUR CODE OR TESTS]
    * HTML::Element::as_XML now only escapes five characters, instead
      of escaping everything but alphanumerics and spaces.  This is
      more in line with the XML spec, and will no longer escape wide
      characters as two (or more) entities.  Resolves RT 14260.  Thanks
      to Carl Franks and somewhere [at] confuzzled.lu for assistance.

    [FIXES]
    * A string comparison was commented to use lc() on both sides, but
      didn't.  This caused HTML::Element::look_down to not properly find
      elements in certain cases.  Thanks to Andrew Suhachov. (RT 21114)

    [TESTS]
    * Added several new tests and enhanced others.  Thanks to Rocco
      Caputo for t/attributes.t, and several others for providing
      test cases in their RT bugs.
