In theory, yes. In practice, when incomplete features are earmarked for a certain release, those features are often rushed out, and not always fully baked. In any case, I don’t think it makes sense to spend too much time planning what goes into 4.0, and what goes into the next major release with so many release strategy related decisions still up in the air. Are we going to ditch tick-tock? If so, what will it’s replacement look like? Specifically, when will the next “production” release happen? Without knowing that, it's hard to say if something should go in 4.0, or 4.5, or 5.0, or whatever. The reason I suggested a production release every 6 months is because (in my mind) it’s frequent enough that people won’t be tempted to rush features to hit a given release, but not so frequent that it’s not practical to support. It wouldn’t be the end of the world if some of these tickets didn’t make it into 4.0, because 4.5 would fine.

To be honest I'd say #12344 is pretty important, otherwise it makes it difficult to replace nodes without potentially requiring client code/configuration changes. It would be nice to get #12344 in for 4.0. It's marked as an improvement but I'd consider it a bug and thus think it could be included in a later minor release.

I don't think anyone expects 4.0.0 to be stable. It's a major version change with lots of new features; in the production world people don't normally move to a new major version until it has been out for quite some time and several minor releases have passed. Really, most people are only migrating to 3.0.x now. While stability is important if we push back large "core" changes until later we're just setting ourselves up to face the same issues later on. There should be enough uptake on the early releases of 4.0 from new users to help test and get it to a production-ready state. Kurt Greaves k...@instaclustr.com www.instaclustr.com
