 ## Compatibility
 
+* `v6.0.0+` works with `golangci-lint` version >= `v1.58.1`.
 * `v5.0.0+` removes `skip-pkg-cache` and `skip-build-cache` because the cache related to Go itself is already handled by `actions/setup-go`.
 * `v4.0.0+` requires an explicit `actions/setup-go` installation step before using this action: `uses: actions/setup-go@v5`.
   The `skip-go-installation` option has been removed.
-* `v2.0.0+` works with `golangci-lint` version >= `v1.28.3`
-* `v1.2.2` is deprecated due to we forgot to change the minimum version of `golangci-lint` to `v1.28.3` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))
-* `v1.2.1` works with `golangci-lint` version >= `v1.14.0` ([issue](https://github.com/golangci/golangci-lint-action/issues/39))
