Is there any documents about Backwards/Forwards compatibility? I want to upgrade etcd server from v3.3.15 to v3.4.0, do I have to update the client code? Or the old version client still works?
Is there any update? we have same consideration.

Update to please the stalebot. This is still important given Etcd's standing in the ecosystem.

I think its very important.
I did some reaserch about API changes since v3.1.0 (there seems to be a lot of change since v3.0.0:)
(mostly based on git diff v3.1.0 ./etcdserver/etcdserverpb/rpc.proto
):
and identified following differences:
All changes were RPC compatible.
IMHO etcd client v3.x.y should:
declare being forward compatible with all >=v3.x.0 releases of etcd server
declare being backward compatible with any >3.1.0+ release of etcd server, with the regards to limited feature set.
Explicitly document new features added in consective etcd clients (and public API).
Move etcd client to a separate go module, such that dependency set is minimal when importing.

Can a human please just explicitly say that this documentation is not going to get written or that it's planned for the future? Marking valid issues stale by bot is not productive.

Hi all,
I can't find any precise documentation around compatibility of v3 clients with given versions and v3 servers with given versions.
While it may be possible to take entire Etcd clusters down and replace them at once, doing that with a larger set of clients is somewhat unrealistic.
Are there any backwards or forwards compatibility guarantees across the client API? For example:
It would be great if you could provide some information about how the Etcd team plans for such scenarios and how you attempt to maintain compatibility, if at all. If not, that should be documented as well.
Thanks!
