Ext JS 3.3 Final Released
October 11, 2010 by Ed SpencerFollowing the successful betas and recent release candidate, we are proud to release Ext JS 3.3, the final major release on the 3.x line. Ext JS 3.3 brings new components, features and performance enhancements, all while maintaining the same robust API. Ext JS 3.3 is a drop-in replacement for Ext JS 3.2 ? most applications won?t require any changes.
