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.
Thanks!

IE11 for Windows 7 Globally Available for Consumers and Businesses
Thursday, November 7, 2013 10:00 AM
Internet Explorer 11 (IE11) is available worldwide in 95 languages for download today. 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.
