Hi @knz, please add branch-* labels to identify which branch(es) this release-blocker affects.
:owl: Hoot! I am a Blathers, a bot for CockroachDB. My owner is otan.
Investigated this further - this seems to happen in 22.1 too so not a GA blocker.
@knz do you know what change introduced the regression?
Yeah it was the big init refactor we did back in 21.1 (or maybe 20.2, I'm not sure), the one that allowed us to simplify/strengthen the upgrade process.
We have a cross-version compatibility guarantee between CLI clients and servers, such that it should be possible to use version N-1 of the CLI to access version N servers, and vice-versa.
There is a regression for this since v21.1 it is not any more possible to use e.g. a v21.2 CLI to operate a v22.1 server, or a v22.1 CLI to operate a v22.2 server.
(The problem still exists in v23.1)
