Ok, the release is out, and it seems everything is well ;-)
One source of complaints was that some had updated pydev and not pydev extensions, and this was not working well... so, I've taken a look and the problem is that when I specified the pydev extensions plugin, I asked for a 'greateOrEqual' match on the version, when a 'perfect' match is what's needed (otherwise, you could get a bunch of error with accesses to invalid methods, attributes, etc)
So, this is fixed for the next release... but until there, those that use both have to remind to update both.
Now, planning for the other release...
One of the nicest things added in the extensions is probably the rename refactoring (which is out, but still in beta), so, I'll probably try to improve the rename refactoring to include matches on strings and comments, and an option to match 'imprecise matches', so that the user can review other potential matches that the pydev analysis ended up discarding.
On the pydev side, I really wanted to go more for the package explorer... it has one issue that I think is critical (commented on: a previous post), and the way to go is probably recreating all the resource-based actions myself... as this can be tricky, I'm not sure it'll be available for the next release...
