- K8s.io/apimachinery/pkg/util/runtime: Added support for new calls to handle panics and errors in the context where they occur. `PanicHandlers` and `ErrorHandlers` now must accept a context parameter for that. Log output is structured instead of unstructured. ([#121970](https://github.com/kubernetes/kubernetes/pull/121970), [@pohly](https://github.com/pohly)) [SIG API Machinery and Instrumentation]
