we are approaching the 3.0 release date. We have built our first release candidate, and we hope to turn this into the final release unchanged soon.
There have been a few changes since the last two betas: The translations are now up to date, more icons have been added to the macro browser, and we have tweaked a few screens, like the profile page. And of course we have fixed dozens of bugs (see JIRA URLs below). We are very pleased with the quality of the release and we are currently not aware of any showstoppers or critical issues. Chances are that the final release will be just a rebranded RC, however you should still not use the RC on production systems, since we still have some final testing planned. We encourage you to use it for staff training purposes and for your upgrade testing though, since no more UI changes or changes to the upgrade process are scheduled.

Thanks for your feedback so far, it has helped us track down a few bugs, which will result in a smoother upgrade for everyone!
