- Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. ([#73892](https://github.com/kubernetes/kubernetes/pull/73892), [@smarterclayton](https://github.com/smarterclayton))

- Apimachinery: Pretty printed JSON and YAML output is now indented consistently. ([#105466](https://github.com/kubernetes/kubernetes/pull/105466), [@liggitt](https://github.com/liggitt))

*   DaemonSet status includes a new field named `conditions`, making it consistent with other workloads controllers. ([#55272](https://github.com/kubernetes/kubernetes/pull/55272),[ @janetkuo](https://github.com/janetkuo))
*   StatefulSet status now supports conditions, making it consistent with other core controllers in v1 ([#55268](https://github.com/kubernetes/kubernetes/pull/55268),[ @foxish](https://github.com/foxish))

- Custom resource requests with `fieldValidation=Strict` consistently require `apiVersion` and `kind`, matching non-strict requests ([#109019](https://github.com/kubernetes/kubernetes/pull/109019), [@liggitt](https://github.com/liggitt))
