We have just published the second beta version of the future Thymeleaf 2.1: version 2.1.0-beta2
When we published beta1, we said it was feature-complete but... well... we couldn't really help adding a couple of things ;-)
Actually, what we did is add a bunch of great new features regarding Spring integration. You can read about them here: http://www.thymeleaf.org/whatsnew21.html (check out "New Features in Spring Integration").
Maven and SourceForge repositories have already been updated, so you can download it, test it, and of course report any issues you might find.
New 2.1.0-beta2 versions have also been published for the Tiles2, SpringSecurity3 and ConditionalComments "extras" libraries. And also for the thymeleaf-testing framework.
This should be the last beta version for 2.1.0. Now we will start updating the docs and... 2.1.0 should be out really soon!
