on to pylons...

I caught up a little bit with respect to turbogears happenings by perusing planet turbogears. Version 2 is going to be built on pylons, SQLAlchemy, genshi, and ToscaWidgets. Does that mean this book I have is basically worthless? OK, now I'm looking at pylons. I notice freebase.com is using pylons. That's a pretty good endorsement.
