The major highlight in this release is the new interactive console. Details on it can be found at: http://pydev.sourceforge.net/console.html.
Pydev extensions also has some pluses regarding the interactive console (see: http://fabioz.com/pydev)
I'll do a video showing it in more details shortly (probably over the weekend).
This release also has some other nice things, such as having the regular console accepting unicode chars that are not in the ascii range (it uses the sitecustomize.py feature from python to set the correct encoding to be used in the shell) and other bugfixes.
Get it while it's fresh :)
