D frontend was merged into GDC master. It is version 2.076 now. 
The older version was merged to make the switch easy and just 
replace the C++ frontend with the same version of the D frontend. 
There is a pull request to merge 2.080-beta into master:

https://github.com/D-Programming-GDC/GDC/pull/683

But some tests are still fail.

There is no nightly builds for DMD. It is currently more 
important to keep GDC up to date with GCC master (I'm updating 
GDC to to work with GCC weekly snapshots), because it would help 
to get GDC merged into GCC.

I can't currently promise anything but I wanted to build GDC 
binaries (gcc-7 or gcc-8) for me with a new frontend (2.080) and 
for Ubuntu, so other people can use it. Not sure how difficult 
will it be to update to the newer D-frontend versions (2.081 ... 
and so on), so not sure if I'll be able to help Iain much with 
that.

I should probably write some announcement about the latest work 
on GDC :).
