I’m not a big fan of spamming you with a super short release cycle, but unfortunately the release of 2.2 revealed a couple issues that we didn’t manage to uncover in the beta and with our tests. I already released 2.2.1 shortly after the initial release to fix some first annoying bugs, which you reported. Today follows another stability release: http://getkirby.com/changelog/kirby-2-2-2
Thank you to all the bug-reporters and those who even sent in pull requests on Github. This is hugely helpful!
Considering all the feedback and additional testing, I think we reached a very stable release now and I’m very happy with the small additions and additional translations that made it into 2.2.1 and 2.2.2.
Now it’s documentation time 
Cheers, Bastian
