This statement kind of worries me:
It seems like every minor release of D works different than previous ones.
Why would you release a version if it wasn't different from the previous?
It would be nice if one could give the oldest known working compiler, but there are still changes to old behavior which means some code would have more specific compiler versions needed.
Work is being done, but the issue will exist for some time so process to make it less painful is being put in place.
