* Beautiful Soup is no longer compatible with Python 2.6. This
actually happened a few releases ago, but it's now official.
* Beautiful Soup will now work with versions of html5lib greater than
0.99999999.
* If a search against each individual value of a multi-valued
attribute fails, the search will be run one final time against the
complete attribute value considered as a single string. That is, if
a tag has class="foo bar" and neither "foo" nor "bar" matches, but
"foo bar" does, the tag is now considered a match.
This happened in previous versions, but only when the value being
searched for was a string. Now it also works when that value is
a regular expression, a list of strings, etc.
* Fixed a bug that deranged the tree when a whitespace element was
reparented into a tag that contained an identical whitespace
element.
* Added support for CSS selector values that contain quoted spaces,
such as tag[style="display: foo"].
* Corrected handling of XML processing instructions.
* Corrected an encoding error that happened when a BeautifulSoup
object was copied.
* The contents of <textarea> tags will no longer be modified when the
tree is prettified.
* When a BeautifulSoup object is pickled but its tree builder cannot
be pickled, its .builder attribute is set to None instead of being
destroyed. This avoids a performance problem once the object is
unpickled.
* Specify the file and line number when warning about a
BeautifulSoup object being instantiated without a parser being
specified.
* The `limit` argument to `select()` now works correctly, though it's
not implemented very efficiently.
* Fixed a Python 3 ByteWarning when a URL was passed in as though it
were markup. Thanks to James Salter for a patch and
test.
* We don't run the check for a filename passed in as markup if the
'filename' contains a less-than character; the less-than character
indicates it's most likely a very small document.
