Problem Description

In #2349, github.com/klauspost/compress is upgraded to v1.15.11, which require at least Go 1.17(link). However, the minimal Go version in sarama is still Go 1.16(link). Thus, if Go 1.16 is used, compilation will fail.

I think it's time to upgrade Go version in go.mod.

😔 whilst I'd seen "deprecate go1.16" in the release notes of v1.15.10 I hadn't spotted that this actually introduced a breaking change (dropping the old +build comments)

officially Sarama only officially supports and tests on N and N-1 versions of Go, but it would have been nice if we'd spotted this pre-release

🤔 I think the release note was not clear. It should be the minimal requirement is Go 1.17 instead of just deprecate Go 1.16.
