Pydev 1.5.6 has just been released (it's the same version as the last nightly build, so, if you were already in the last nightly build, there will be no upgrade available).
As commented before, the major highlight in this release is the Django integration.
There are more details on that at: http://pydev.org/manual_adv_django.html
Other additions worth commenting are:
* The go to definition (F3) now works with unsaved buffers
* Some improvements were done in the auto-edition to automatically close literals
* On backspace, the closing literal or parenthesis may be deleted
* Ctrl+2+s word to search can be used to search for a string in open editors (and that can no longer be done through the find/replace dialog)
