 This action sets up a go environment for use in actions by:
 
-- optionally downloading and caching a version of Go by version and adding to PATH
-- registering problem matchers for error output

-- Proxy Support
+The V3 edition of the action offers:

+- Adds `GOBIN` to the `PATH`
+- Proxy support
 - Check latest version
-- Bug Fixes (including issues around version matching and semver)
+- Bug fixes (including issues around version matching and semver)
 
 The action will first check the local cache for a version match. If a version is not found locally, it will pull it from the `main` branch of the [go-versions](https://github.com/actions/go-versions/blob/main/versions-manifest.json) repository. On miss or failure, it will fall back to downloading directly from [go dist](https://storage.googleapis.com/golang). To change the default behavior, please use the [check-latest input](#check-latest-version).
