 ### Status
 
 We're currently in the development phase, version 3.1dev. 3.1dev will eventually become 3.2. Bigger features are developed in a separate branch before merged into 3.1dev to avoid hiccups or inconsistencies. Albeit we try to keep 3.1dev as solid as possible things will certainly change in 3.1dev. So if you need stability the 3.0 branch is better for you. Think of the 3.1dev branch like a rolling release.
