- Added the `applyconfiguration` generator to the code-generator script that generates server-side apply configuration and client APIs ([#114987](https://github.com/kubernetes/kubernetes/pull/114987), [@astefanutti](https://github.com/astefanutti))

* API discovery failures no longer crash the kube controller manager via the garbage collector. ([#55259](https://github.com/kubernetes/kubernetes/pull/55259), [@ironcladlou](https://github.com/ironcladlou))
* Fix bug where master startup script on GCP failed randomly due to concurrent iptables invocations. ([#55945](https://github.com/kubernetes/kubernetes/pull/55945), [@x13n](https://github.com/x13n))

- Projects which use k8s.io/code-generator and invoke `generate-groups` or `generate-internal-groups.sh` have a new, simpler script (`kube_codegen.sh`) they can use.  The old scripts are deprecated but remain intact. ([#117262](https://github.com/kubernetes/kubernetes/pull/117262), [@thockin](https://github.com/thockin)) [SIG API Machinery and Instrumentation]

- KCM specific args can be passed with `/cluster` script, without affecting CCM. New variable name: `KUBE_CONTROLLER_MANAGER_TEST_ARGS`. ([#120524](https://github.com/kubernetes/kubernetes/pull/120524), [@jprzychodzen](https://github.com/jprzychodzen)) [SIG Cloud Provider]

must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework.
