On behalf of the Jython development team, I'm pleased to announce that Jython 2.5a2+ is available for download http://voxel.dl.sourceforge.net/sourceforge/jython/jython_installer-2.5a2.ja....
See the installation instructions http://jython.org/Project/installation.html.
Django runs pretty well on this release. I am attending Djangocon where Jim Baker and Leo Soto will be presenting on Django on Jython, and I wanted them to be able to tell people to grab a release instead of telling them to grab Jython from svn.
There are many bug fixes, but also many bugs that have not yet been fixed.
This is an alpha release so be careful!
