Hi, Keith.
Yes, I've been quietly releasing all kinds of little patches (and I guess some not so little...) I was holding off on announcing a new version until they were all a bit tested out, and I had a chance to document them. There's some info on the patches in the Version History in the distro. Things of interest might be: SPLIT BY/splitValue/splitIndex, RegEx support, some more kinds of literal strings (Raw and Rich), and some new Geom functions.
One thing I haven't done is the Polygonize command you asked for! If you're still interested in that I'll try and get on that next.
