We are pleased to announce today the availability of Ext JS 4.1.1 RC1.

http://cdn.sencha.io/ext-4.1.1-rc1.zip

Of particular interest in this release are some significant fixes for community reported layout issues. We wanted to get these fixes out as early as possible to provide an opportunity for community feedback.

The plan is to close as many community-reported bugs as possible for the final Ext JS 4.1.1 so a big "thank you" to everyone who has taken the time to report their issues.

Enjoy!
