WordPress has updated its filenames to start with wp- a more stable (and I hope final) change. I’ll port my in-house hacks to a more stable version while I’m at it, and then look to writing some plugins. I hooked up a CVS client to look into its progress last week and I was pleasantly surprised: Readable URLs are a big plus, and various smaller tweaks which would make WordPress much nicer to use. I hope the new version comes out soon.
