The wxPython project’s Phoenix release is slowly coming along. Phoenix is the codename for the new wxPython that will support both Python 2.x and 3.x. Anyway, Andrea Gavana has put together some autogenerated documentation using Sphinx on top of Doxygen. You can read about the announcement including any known issues on the wxPython mailing list.
For those of you who are brave, you can also read about a snapshot build of Phoenix here or download the a tarball here. Note: These tarballs are only for Mac and Window users and they are not completely working.
For those of you who don’t know anything about Project Phoenix, you can read about it on the wxPython wiki.
