### API Change

- A few log calls which did not properly format their parameters were fixed. ([#137108](https://github.com/kubernetes/kubernetes/pull/137108), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, Cluster Lifecycle, Network, Node, Scheduling and Testing]

- Resolves a spurious "Unknown discovery response content-type" error in client-go discovery requests by tolerating extra content-type parameters in API responses ([#117637](https://github.com/kubernetes/kubernetes/pull/117637), [@seans3](https://github.com/seans3)) [SIG API Machinery]
