Ext 2.2 was dropped a few hours ago. Some of the major features include a multi-select box and file upload button, both of which are amazing. A new history manager is something that took a lot of us by surprise. I cannot wait to start poking around with this. Firefox 3 is now officially supported, which is a very welcome change 
. Great job to the Ext team for a fabulous release.
