It’s because of me, not upstream – I had a busy period and so had a backlog of releases to package.
Last few upstream releases:
https://github.com/dlang/dmd/releases/tag/v2.076.0 (1 Sep 2017)
https://github.com/dlang/dmd/releases/tag/v2.077.0 (2 Nov 2017)
https://github.com/dlang/dmd/releases/tag/v2.078.0 (2 Jan 2018)
… and I’d anticipate the 2.079.0 release will be some time between the end of this week and the next.
So, it looks like they might have upped the cadence a bit to once every 2 months, not 3, but that could be just a short-term thing.
I can check in if you’re concerned about proliferation of tracks, but I don’t anticipate such a short turnaround for the next request.
By the way, thank you for the careful scrutiny on things like this (as for the ldc2 snap). I do appreciate it, as it helps me to regularly re-evaluate how I’m thinking about managing these packages.
