Faster and more stable than 8.0 would be nice; we'll see if that works out in practice. Also, I've configured my environment to use JDK 1.6 (not 1.5) as the default JDK; so that should help with performance as well. I need to decide whether compiling with JDK 1.6 but targetting JDK 1.5 is sufficient for Tapestry releases, or whether I should switch back to 1.5 when creating releases.
Meanwhile, I've been updating my training workshop (in case I end up teaching at Skills Matter in London any time soon), and I'm switching over to using Eclipse, not IDEA, for the workshop. I think people will appreciate the familiarity of Eclipse, even under Ubuntu. There goes my chance to change the world, though!
