Yes! My copy of Extreme Programming Explained, 2nd edition arrived today, just in time for me to catch up with Kent's latest thinking before the XP course I'm running across the border(s) in January. I don't yet know how I will react to the updated edition since I haven't even opened it yet, but it sure is good to know what he's writing today if someone happens to ask... It's been almost a decade since the first "XP" project was started so it wouldn't be a surprise if someone would ask about the evolution during all those years -- a bit like the recent thread in the XP Yahoo! group about the timeline of when was TDD merged into XP.

1. JSP 2.1 to support pluggable VariableResolvers
2. A new Apache JDO proposal

Maybe this is the answer :)
