Hi all!

I merged the merge-2.068 branch into master. The master branch 
now contains the code for next release 0.17.0, based on frontend 
release 2.068.2.

Again, please note that starting with this version we have drop 
support for LLVM versions 3.1 - 3.4. Travis-CI already reflects 
this.

You can expect a bugfix release 0.16.1 and next alpha 
0.17.0-alpha1 soon.

Regards,
Kai
