- 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]...

## Introduction to 1.9.0

Kubernetes version 1.9 includes new features and enhancements, as well as fixes to identified issues. The release notes contain a brief overview of the important changes introduced in this release. The content is organized by Special Interest Group ([SIG](https://github.com/kubernetes/community/blob/master/sig-list.md)).

* Add a check for file size if the reading content returns empty ([#33976](https://github.com/kubernetes/kubernetes/pull/33976), [@jingxu97](https://github.com/jingxu97))
* Add a retry when reading a file content from a container ([#35560](https://github.com/kubernetes/kubernetes/pull/35560), [@jingxu97](https://github.com/jingxu97))

        /*

         * and increasing the threshold to 2^32 doesn't pay for itself, and adding another enum
         * constant hurts performance further -- I suspect because bimorphic implementation is a
         * sweet spot for the JVM.
