for full details for 0.9.4b1 see the relevant CHANGELOG: 
http://cssutils.googlecode.com/svn/tags/TAG_0.9.4b1/CHANGELOG.txt

0.9.4b1
     - **FEATURE**: Added ``csscombine`` script which currently resolves 
@import rules into the input sheet. No nested @imports are resolved yet 
and @namespace rules do not work yet though!

     + **BUGFIX**: Serializing escape sequences add a single SPACE after 
each escape. This was not present until now so a sequence like "\\74 a" 
did come out as "\\000074a" which was not as intended. Also as a SPACE 
is inserted in any case all escapes are not padded to 6 digits anymore 
but are only as long as needed.

     + **BUGFIX**: Handling of illegal selectors is now same as the W3C 
CSS validator (and according the selector spec - I hope ;). Illegal 
selectors result the complete rule being dropped. Fixed are the 
following (edge) cases:

       ``a/**/b``
         Meant was probably a space between a and b (plus maybe the 
comment) but it MUST be inserted. IE and Safari nevertheless seem to 
parse this rule as ``a b`` so as if a space would be present. cssutils 
now parses this selector as intented by the spec as ``ab``.
       ``a*b``
         Again spaces around the UNIVERSAL ``*`` were probably meant by 
the author. IE and Safari seem to parse this **invalid** selector as ``a 
b``. cssutils ignores this rule completely!

     + BUGFIX: ``css.CSSRuleList`` is still a Python list but setting 
methods like ``__init__``, ``append``,     ``extend`` or 
``__setslice__`` are added later on instances of this class if so 
desired. E.g. CSSStyleSheet adds ``append`` which is not available in a 
simple instance of this class! This has been changed as no validation is 
possible in CSSRuleList itself.

     + IMPROVEMENT: Added better ``str`` and ``repr`` to 
cssutils.serializer.Preferences

     + IMPROVEMENT: Added position information to some error reportings 
(Property, CSSMediaRule

     + some internal changes
