I have no idea who released PW 1.3, and it kind of annoys me that they didn't even bother to update the README. When I released 1.2, I specifically asked both Euclid and SePH for their permission to release an update under the same name, otherwise I would have created a fork like Parallel Remodel. By updating under the same name, but with no README or any author information, now I'm getting a bunch of bug reports sent to me for a version I didn't even know existed, and I have no idea what was changed in this version
All I can say is, you'll have to figure out who actually released 1.3 if you want any answers about the new issues. I know 1.2 had its problems, and I'm working on fixing them, but I have a bunch of other projects on my plate too.
