This Pydev release was focused mostly on bug-fixes, with many minor things being done. It fixed that nasty bug related to handling __all__ incorrectly together with a bunch of others.
I think that the only feature added that's worth mentioning is a mode where you can have Pydev analyze only your current editor (this enables builds to happen faster, as less work is needed when building the project, so, it can increase your performance a bit at the cost of having the markers added only to open editors). To activate it, go to window > preferences > Pydev > Builders and check 'Only analyze open editors'.
Note that doing so will not remove existing markers, and will be available for new analysis (the markers may be removed by right-clicking a folder and choosing "Pydev > Remove error markers"). Also, this feature is still in beta, so, please report any bugs found when using it.
