 ## Known bugs
 
-* https://github.com/actions/setup-go/issues/14
-
-The `setup-go` action doesn't set `PATH`, so currently it's not possible to `go
-install` a program and run it directly. Until that's fixed, consider absolute
-paths like `$(go env GOPATH)/bin/program`.
-
-A workaround is to use a built-in [workflow command](https://help.github.com/en/actions/reference/workflow-commands-for-github-actions#adding-a-system-path)
-to add `GOBIN` to the system's `PATH`. Note that `shell: bash` is supported on
-all platforms:
-
-```yaml
-    - name: Add GOBIN to PATH
-      run: echo "::add-path::$(go env GOPATH)/bin"
-      shell: bash
-```
-
-Note that the upcoming `actions/setup-go@v2` fixes this issue, but is still in
-beta as of April 2020.

 `git config core.autocrlf` defaults to true, so be careful about CRLF endings in
