go.mod declares invalid Go version 1.23.7, breaking go install

[beneteos]

Hi 👋

It looks like the go.mod file in version v0.21.0 specifies an invalid Go version : go 1.23.7

This causes go install to fail with the following error:

go: github.com/google/go-jsonnet/cmd/jsonnet@latest (in github.com/google/go-jsonnet@v0.21.0): go.mod:3: invalid go version '1.23.7': must match format 1.23

The Go version directive should use the format major.minor (e.g. 1.23) without the patch component.

This is currently breaking CI pipelines that run:

go install github.com/google/go-jsonnet/cmd/jsonnet@latest

Could you please correct the go.mod file to use a valid Go version? Thanks a lot for your work!

Thanks for reporting it. I suppose it was predictable that I would miss something with this release. We must have some missing CI coverage too since this wasn't caught during the release process. I'll fix when I'm able, but it won't be for several hours (and maybe not until tomorrow). Consider pinning to v0.21.0-rc2 or -rc1 and seeing if that works for you for now.

Ok, I've looked into this in more detail and this is not actually an error in the go.mod file. The go 1.23.7 statement is correct - the format changed in Go 1.21. See golang/go#63370 (also golang/go#71363, golang/go#63279, golang/go#61851)

go-jsonnet was bumped up to Go 1.23 in #794 - Go 1.23 is required by recent versions of golang.org/x/crypto, so when we upgraded that dependency we also had to upgrade Go version.

If it's possible for you to upgrade to Go 1.23.7 or above, it should work. Note that the Go project itself only supports the most recent two major release series, if I'm interpreting the release policy correctly (https://go.dev/doc/devel/release#policy), so the 1.23 series is already the oldest supported.
