2.2.4.2 (stable): * Namespace sigc is now documented, in order to make large chunks of the reference reappear. (Daniel Elstner) * The shipped reference documentation has been regenerated using Doxygen 1.6.1, so that the document type is now XHTML 1.0. (Daniel Elstner) * The shipped Devhelp file has been generated with a newer version of the XSLT script in mm-common, so that documentation groups no longer appear as namespace prefixes in the keyword list.
