As you probably know, yesterday we've tagged and built the 4.4.3 RC build, to maintain stability and to allow work on 4.4.4 we have branched 4.4.3 so:

For your 4.4.4 work - just push to master

For 4.4.3 work (blockers/exceptions only!) - push to master and once it's merged backport to the ovirt-engine-4.4.3.z branch

Thanks!
