- Fixed EDITOR/KUBE_EDITOR with double-quoted paths with spaces when on Windows cmd.exe. ([#112104](https://github.com/kubernetes/kubernetes/pull/112104), [@oldium](https://github.com/oldium)) [SIG CLI and Windows]
- Fixed a bug in the JSON frame reader that could cause it to retain a reference to the underlying array of the byte slice passed to Read. ([#123620](https://github.com/kubernetes/kubernetes/pull/123620), [@benluddy](https://github.com/benluddy)) [SIG API Machinery]
