Wow, this version is really cool! Not everything is working correctly yet, but when Mark finishes his list he will probably find some time to help me fix my bugs :-). Now I find out how to connent to irc.freenode.org (thanks tumtum) I could ask there as well, though the problems are a bit more complicated, since it is not about a useal install.
I'm not sure if they did it for Mark Pilgrim, but there is now a new input option, "slugs", so you can make you own custom URI's. Another major feature (for me) is that I can keep my WordPress files in a separate directory, instead of everything based in the root. Previously, I did this using a hack, but that only worked for most options, not all. Now there is an option for it everything works perfectly!
Slugs were a common request, but yes, I was one of the people who requested it.
