Plan to upgrade goVersion for etcdctl?

[caixiangibm]

What happened?

Downloaded the latest etcd-v3.5.6 and check etcdctl go version information.
We found its go version still with go1.16.15

# go version etcd-v3.5.6-linux-amd64/etcdctl
etcd-v3.5.6-linux-amd64/etcdctl: go1.16.15 

What did you expect to happen?

When will etcd use latest go version of go 1.19.3 or 1.18.8 to build and release newer version?

How can we reproduce it (as minimally and precisely as possible)?

just run: go version etcd-v3.5.6-linux-amd64/etcdctl

Anything else we need to know?

No, we don't usually backport golang minor version upgrades and go1.17 has some breaking changes. Details in #14105 (comment)

[caixiangibm]

But it seems there was PR for go version 1.19.3?
#14678

[serathius]

This is the main branch used for development.

[caixiangibm]

Given that there is go version 1.19.3 master branch for development , the newer go version for etcd is in development and evaluation ?

[serathius]

Next release of etcd (v3.6) is expected to launch with (+/-) latest available go version on the time of the release.
