View Full Version : need to avert IE11 crisis requires ExtJS v3 update

8 Nov 2013, 6:26 AM
We need ExtJS v3 to support IE11 before Windows 7 consumer machines are auto-updated or all deployed ExtJS Web Apps risk immediate failure.

Sencha - please assure us that this support is forthcoming very shortly.

Internet Explorer 11 (IE11) is available worldwide in 95 languages for download today (http://windows.microsoft.com/ie). We will begin automatically updating Windows 7 customers to IE11 in the weeks ahead, starting today with customers running the IE11 Developer and Release Previews. With this final release, IE11 brings the same leading standards support--with improved performance, security, privacy, and reliability that consumers enjoy on Windows 8.1—to Windows 7 customers.

That's excellent news! Thanks.

I have never had an issue because I use the compatibility meta tag IE provides.
My company only supports IE7 & 8 but I've also made sure IE9 works as well as Chrome, Firefox, Safari, and Opera.

Using Ext JS library 3.4.0 I've already tested this with IE10 and IE11 with no issues.
