It's nothing at this point.

The current version of the language is D2 (2.105.3 being the latest release), and whenever discussions on language changes that would be too large to do in D2 (or which Walter simply doesn't want to do) come up, folks sometimes talk about there being a D3 where we can then make all of the breaking changes that we might want to make but can't in D2, because it would break too much.

We may eventually have a D3, but there are no plans for it. It just keeps coming up because of folks wanting changes that they can't get in D2, and they think that they could get them with a D3.

Walter and Atila are looking into adding Editions to the language so that we can make larger changes in D2 while still letting older code continue to work as-is, so that may allow more of the types of changes that typically get lumped into D3, but if anything, it makes the existence of D3 even less likely. But we'll have to see what actually happens with Editions to see what kinds of changes will be possible.

I see. Thanks for the explaination.
