================
* Support for parsing microformats, including rel=enclosure, rel=tag, XFN, and hCard.
* Updated the whitelist of acceptable HTML elements and attributes based on the latest draft of the HTML (HyperText Markup Language) 5 specification.
* Support for CSS sanitization. (Previous versions of Universal Feed Parser simply stripped all inline styles.) Many thanks to Sam Ruby for implementing this, despite my insistence that it was impossible.
* Support for SVG sanitation.
* Support for MathML sanitation. Many thanks to Jacques Distler for patiently debugging this feature.
* IRI (International Resource Identifier) support for every element that can contain a URI (Uniform Resource Identifier).
* Ability to disable relative URI resolution.
* Command-line arguments and alternate serializers, for manipulating Universal Feed Parser from shell scripts or other non-Python sources.
* More robust parsing of author email addresses, misencoded win-1252 content, rel=self links, and better detection of HTML content in elements with ambiguous content types.
