> **Use instead:**
> - [`github.com/Masterminds/semver/v3`](https://github.com/Masterminds/semver) — parsing, comparison, and constraint matching (replaces `Version` and `Constraint`).
> - [`golang.org/x/mod/semver`](https://pkg.go.dev/golang.org/x/mod/semver) — if you only need to compare canonical `vX.Y.Z` strings.
> - The `Migration` up/down helper had no third-party equivalent and was only used by `go/sqaffold` (also archived). For database migrations use [`github.com/pressly/goose`](https://github.com/pressly/goose).
