Pretty much. Our CI script can be used as a reference too.

C++ headers are aligned with 2.076, as well as all regressions in 
the changelog backported.  We can build phobos 2.076 and pass all 
unittests. Not all features have been backported from D however. 
Notably static foreach in the upcoming release (and I have no 
plans to port it).

Moving to self hosted (ddmd) is something that will happen soon.
