Five months in the making. There is always a great sigh of relief when a release is shipped. Things are getting trickier now since we have to be fully backward compatible with earlier releases, there's alwasy this nagging doubt in the back of my mind that we've broken something important to someone. With all the possible permutations and combinations of test scenarios testing every possibility is near on impossible. This is mostly why we run early release copies on puakma.net. there are a number of applications up there that do all sorts of wierd and wonderful things, and if something is broken we'll find it pretty quickly.
The 3.22 release was an important one. We shipped computed page functionality and parent page functionality which required some heavy rewriting of the page rendering internals. With every rewrite comes the risk of something not working exactly like it did before.
3.22 is also the base release for Vortex IDE which is now in beta. Everyone testing the IDE should have 3.22 or greater. I am using the IDE currently for a customer project and having great results (backing up regularly just in case!). I think it compares favourably to the likes of Lotus Domino Designer (except runs on almost everything and you can develop through firewalls). Our plans for future releases of Vortex have some REALLY cool features to further cut development time.
