Yeap, it's available for those that really want to keep up with the most up-to-date code...
The nightly build is available in the format of an update site.
The update site links to use are:
Instructions on how to use it are available at:
Until now, Pydev didn't have an easy way for people to get updates until a proper release was all wrapped up, so, this should be pretty handy for those of you expecting a bugfix -- or just wanting to experiment with the latest thing you're waiting for. Also, usually before committing I do run the Pydev test-suite (which is pretty big), so, it should be regularly pretty stable.
Another thing: I've been having some complains on people not being able to access fabioz.com, even with the server being up (it appears it's related to some specific providers), so, that update site can be used as a second choice if you're not currently able to access fabioz.com to get Pydev Extensions (also note that we're -- still -- in the process of moving Pydev things to Aptana, so, hopefully as soon as that's done, no one else will have any problems accessing the Pydev site).
A note for those expecting bugfixes: The Pydev builds now contain not only the current version, but also the repository id in the build (e.g.: 22.214.171.1243), so, if the svn version for a fix is known (I usually post it when I fix a bug), you can wait for the build to get to that version and then get it ( the current nightly build version can be verified at http://nightly.aptana.com/pydev/site.xml and http://nightly.aptana.com/pydev-pro/site.xml )
