Congratulations are in order.

I have a question from Digger's perspective:

Which version of DMD will be required to build DDMD?

Will DDMD code be constrained to the feature set of DMD 2.067?

Will future DMD versions promise to never break any DDMD code 
from any point in time?

I certainly hope we aren't going to need a long daisy chain of 
DMD versions in order to build DMD completely from source...
