We just released the Qt Creator 3.0 release candidate, together with the Qt 5.2 release candidate. We have been doing a lot of bug fixing since the beta release, and think that Qt Creator 3.0 is now relatively close to what we would like to release as the final. So we would really like you to have a try and report remaining issues that you find. Please use our bug tracker at bugreports.qt-project.org for that, project “Qt Creator”, the best fitting component, and “Affects Version: 3.0.0-rc1″.

If you are interested in what the new features in 3.0 are, please head over to the beta release blog post, or have a look at the (not yet complete) change log.
