For now we are still on 1.6 because most features still target 1.6. To support development of future version we should move to 1.7.
- Master build package will contain 1.7 in name instead of 1.6
- There will be branch with name `releases/1.6` containing everything up until the current master
- There will be integration test loop running for 1.6 as well as master
- We will include 1.6 in our weekly summary every monday
- (optional/nice to have) performance tests comparing 1.7 to 1.6?
