The Ext Team has been hard at work creating documentation for the 2.0 release. We now have several documents for new and existing Ext users that should come in very handy during the transition to 2.0.

Introduction to Ext

If you are brand new to Ext, you should start with our original tutorial, the Introduction to Ext. This tutorial was created for the original 1.0 release, but has been newly updated for 2.0. This is a great place to start if you’ve never written any code in Ext.

Ext 2.0 Overview

The Ext 2.0 Overview is primarily intended for those with some prior experience with Ext, as it dives into some advanced topics.
 

Ext 1.x to 2.0 Migration Guide

Existing 1.x users should be happy to see the 1.x to 2.0 Migration Guide.

API Documentation

The developer API documentation has been fully updated for 2.0 as well. Along with the newly-designed doc center, it’s now easier than ever to find the help you’re looking for.

Final release

The final release for 2.0 is currently scheduled for November 15th.
