Today was released last candidate for 2.2.1 - Seam 2.2.1.CR3. This version was still focused on bug fixing and on JBoss AS 6 CR1 as runtime deployment.
There were fixed 32 bugs, upgraded Wicket support to 1.4.14, Javassist to 3.12 to eliminate some bugs with proxy objects. We support JBoss AS 6 CR1 deployment with almost all examples, Spring, dvdstore, blog and jee5-booking have got special build script for JBoss AS 6, which enables packaging and deployment to AS 6.
