Exciting new Sencha (EXTJS version4) has arrived.
The interesting question is "So what exciting about it????"
The following are to name a few.
The Ext.Data package has been overhauled with interesting additions.
Its not last but the UI which matters the most is now supported by CSS3 themes, and the theme has been overhauled to give more richness with reduced size on browser.
Last but not the lease the "Performance" aspect has been improved drastically.
The reduced size load at DOM(i.e. DOM reduction) with an implied and tuned effect on speed gains. And the most interesting is the Infinite Scroll on Grids with data request on demand to scroll.
