remove old versions from pkg.go.dev

Question

I have this Go package on GitHub. and on GitHub I've delete old version tags. but on: https://pkg.go.dev/example.com/username/pkg it still showing those old versions.

I'm wondering how to completely delete those old package from pkg.go.dev

Answer 1

Go module versions are immutable: you cannot invalidate them by simply removing tags, because if you then reused those tags you would cause checksum mismatches for existing users.

Instead, you can use the retract directive in your go.mod file to warn users to avoid versions in a specific range, and to cause the go command not to add new dependencies on those versions by default.
