After changes to the class archetype system for Pathfinder, the psionic classes no longer have archetypes available.
Psionic classes should now be in step with the new archtype set-up.
Doug, I noted in your last commit for Unlimited Possibilities that you removed a few ability categories that I had added. Did you do that on accident or on purpose? Those ability categories are required to properly handle the Adopted Trait.
Not on purpose. Adopted trait ability categories added back into Psionics Unleashed (which I think is the most appropriate place for them).
