For some time NetXStudio which has a 3.x RCP component is build against
Kepler. The e4 3.x compat mode kicks in and besides a few small issues
it works nicely. I do however get depreciation warnings i.e ActionSets
Now it's been said that Luna will address or make some early steps
towards mixing e4 3.x compat. mode and have pure e4 contributions.
I have looking for Luna release notes and tried to find info on this
topic, with surprisingly little luck. Perhaps it will be addressed a
Econ NA also. Anyway, if there is already some information or sample
code on what can be expected in Luna, this would really be great.
