+ * Security fix to enhance sanitizing of CSS in style attributes. Genshi's
+ `HTMLSanitizer` disallows style attributes by default (this remains
+ unchanged) and warns against such attacks in its documentation, but
+ the provided CSS santizing is now less lacking (see #455).
+ * Fix for error in how `HTMLFormFiller` would handle `textarea` elements if
+ no value was not supplied form them.
+ * The `HTMLFormFiller` now correctly handles check boxes and radio buttons
+ with an empty `value` attribute.
+ * Template `Context` objects now have a `.copy` method.
+ * Added a simple `tox.ini` file for using tox to test against multiple
+ * Fix for bug in `QName` comparison (see #413).
+ * Fix for bug in handling of trailing events in match template matches
+ * Fix i18n namespace declaration in documentation (see #400).
+ * Fix for bug in caching of events in serializers by no longer caching
+ `(TEXT, Markup)` events (see #429).
+ * Fix handling of `None` by `Markup.escape` in `_speedups.c` (see #439).
+ * Fix handling of internal state by match templates (relevant when multiple
+ templates match the same part of the stream, see #370).
+ * Fix handling of multiple events between or on either side of start and end
+ tags in translated messages (see #404).
+ * Fix test failures caused by changes in HTMLParser in Python 2.7 (see #501).
