NOX 0.5 has been added to the download page and pushed to the noxrepo git repository.  The major changes include removing dojo, restructuring of authenticator, and many bugfixes.  Users of 0.4 can probably upgrade to 0.5 without requiring any major restructuring.  You can download the source releases here:
