Hi
I don't know about details. It is possible to talk with them directly or even just read their PPA page and see if they answer such questions there.
If they do have 2 branches then i doubt they do it in such a stupid way. They are not morons!

So the PPA has the newest version of both branches.
Does that mean that the newest that will be updated to right now will be
4.1.2, but in a few weeks the update manager will see that 4.0.6 is the
newest and try to update your 4.1.2 back to that one?
