Introduction On behalf of Sencha and the entire Ext JS team, I’m proud to announce that we are releasing Sencha Ext JS 5 today. Ext JS 5 is a huge step forward, and we want to take a moment to thank our community for all of the feedback and constant support. This was the highest beta engagement in our history, with over 100K+ downloads. Together, we have created the world’s most advanced multi-dev
