We're happy to announce that we've updated our support for the Ext JS library to the latest version, 2.2. Ext JS 2.2 contains numerous bug fixes and feature enhancements, including full Firefox 3 support, improved checkbox and radio groups, a history component, and a GMapPanel extension that packages Google Maps functionality into an Ext component. It's also fully backwards-compatible, so you should be able to move to this version from 2.0 without difficulty (though you can also install 2.2 into Studio alongside 2.0 if you want).

The Ext JS 2.2 plugin for Aptana Studio provides code completion, code assist, Ext JS 2.2 examples, project wizards and more atop solid javascript coding and Ajax debugging utilities so that you can be as productive as possible with Ext JS.
