@bitsofinfo’s issue received an interesting answer from @bretfisher (Docker captain):
Swarm is alive and well. There’s no roadmap that I know of that’s kept up to date. The docker/swarm links you refer to is Swarm Classic, a solution used before SwarmKit was released in 1.12 (July 2016) that replaced the similarly named Swarm repo. docker/swarm is now deprecated in favor of this repo (aka Swarm Mode, or just Docker Services). Lots of Swarm fans at DockerCon.
I wrote a few months ago about Swarm’s future, which received

Also, I gave a session on Swarm production and it was voted a top session and was repeated on the last day. It was a full house: https://twitter.com/BretFisher/status/1007099831783862272
So true, there is no public roadmap for SwarmKit, though one could argue you might look at recently updated PR’s but that’s not a guaranteed list of future features.
If you want to learn what’s changed recently, you can look at the Docker CE release notes… looking for anything Swarm Mode and Overlay Networking related.
Also of note, as Docker Captains, we were lucky enough to sit with various Docker Inc. product managers At DockerCon 2018 and they were all committed to the future of SwarmKit/Swarm Mode, saying that customers loved it. At this point I think it’s just a question of engineering priorities across the Docker toolset and bugfixes vs. new features… but I can’t speak for Docker Inc. directly
