Implemented as of Subversion revision 23042.
As an aside: while implementing the errata, I noticed that many, many class abilities in this data set contain nothing more than a pasted text entry, where no formulas or level prerequisites have been applied. Furthermore, it seems, a lot of our usual implementation standards for Pathfinder RPG data set haven't been followed. All in all, this set could benefit from a thorough overhaul to bring the implementation up to our usual standards. I have opened to tackle this.
I have added the official FAQ errata for the Crane Riposte feat that became unclear after the errata change to Crane Wing.
