Seaside, my other favorite framework, released version 2.8 today. This release has been optimized and optimized some more, as it doubles the average page rendering speed, and now uses up to 4 times less memory. Plus it supports Gemstone, which is the feature that I'm most excited about playing with.
The official release page is here, and if you still haven't tried Squeak, a great new tutorial can be found here.
Congrats to the entire Squeak team on this one.
(Seriously though, who does a release on a Sunday? You guys are nuts.)
