+* Pass error message to the ParseError exception in strict parsing mode.
+
+* Allow data URIs in the sanitizer, with a whitelist of content-types.
+
+* Add support for Python implementations that don't support lone
+ surrogates (read: Jython). Fixes #2.
+
+* Remove localization of error messages. This functionality was totally
+ unused (and untested that everything was localizable), so we may as
+ well follow numerous browsers in not supporting translating technical
+ strings.
