We've been celebrating without you on the announce list!

Unfortunately it's going to slow down for a little while.  The files I've 
done post-switch were only left in C++ because they used a small part of the 
backend headers and were easier to do by hand instead of converting 
automatically.  The rest of the glue layer/backend (~90 c++ files) is going 
to need a conversion project of the same scale as the frontend one, preceded 
by a refactoring project 10 times the size of the frontend one.

Walter's recent backend cleanup PRs are working on this, and I'm working on 
a backend test suite to make refactoring safer.

We could see DMD be 100% D within six months, depending on how much free 
time I have and how picky Walter is about my refactoring PRs.
