PrettyFaces 3.3.2 is the current stable version. Lincoln and I are currently working on PrettyFaces 4.0. During this work Lincoln rewrote most of the core parts of PrettyFaces and separated them into the new project Rewrite. Our current plan is to build PrettyFaces 4.0 on top of Rewrite. So Rewrite will actually provide the core functionality for PrettyFaces 4.0. Rewrite currently only supports a programmatic configuration style. PrettyFaces 4.0 will certainly support more like XML and annotations. Further more Rewrite is a very modular and extensible framework. You can do nearly anything you like with it. So PrettyFaces 4.0 will certainly now allow to configure ALL of the Rewrite features with XML/annotations.
I hope this clears up the current situation a bit.
