Sorry for the delayed response. I was travelling the whole week and didn’t find any time to have a deeper look at my inbox!
We are currently working on PrettyFaces 4.0 which is developed in the current “master” branch. Yes, this version (4.0 in the “master” branch) will replace the old one. The old PrettyFaces 3.x code can be found in the “3.x” branch. We are doing the maintenance releases for 3.x from this branch.
