Ext JS 4.1 RC2 Released发布

原文：http://www.sencha.com/blog/ext-js-4-1-rc-2-released/

Today we’re making available Ext JS 4.1 RC2, which contains bug fixes, enhancements and documentation improvements based on your feedback on our first Release Candidate two weeks ago.

The Release Candidate stage is all about polish, whether it’s on the framework, the examples or other sections like the documentation. Much of the work we have done since RC1 has been driven by the feedback we’ve received from the community; we’re always grateful for your bug reports and suggestions on the forums and we’re working hard to make the framework deliver based on your feedback.

Today we’d like to ask you to download RC2 and test it against your apps. If you haven’t used a 4.1 release yet we hope you’ll be pleasantly surprised by the performance improvements over 4.0.x, and if you have then we hope the additional polish since RC1 will make your apps feel and behave even better.

As we close in on a 4.1 GA release your feedback is more important than ever so we hope you’ll take a little time to test RC2 with your apps and let us know how it feels. We’ve prepared a full set of release notes and known issues for RC2, and we’ve put the latest examples online too.

Let us know what you think in the comments and the forums!
