Why is qtcreator updated to 3.0.1.git then 3.1.0beta1?

[GSC <xgdgsc@xxxxxxxxx>]

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?
