[arch-general] Why is qtcreator updated to 3.0.1.git then 3.1.0beta1?

I noticed recently that qtcreator is updated to such non-stable versions, and there is no critical bug related that require such updates on the bug tracker. What is the reason this package is updated to such versions so early? I remember there used to be similar early updates with earlier versions of this package. Is it just the maintainer gets too excited?
