- 'Container `preStop` and `postStart` lifecycle handlers using `httpGet` now
  honor the specified `scheme` and `headers` fields. This enables setting custom
  headers and changing the scheme to `HTTPS`, consistent with container
  startup/readiness/liveness probe capabilities. Lifecycle handlers configured
  with `scheme: HTTPS` that encounter errors indicating the endpoint is actually

- EndpointSlice controller now handles terminating pods correctly and is better at preventing race conditions. ([#89118](https://github.com/kubernetes/kubernetes/pull/89118), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

- K8s.io/apimachinery: runtime.DefaultUnstructuredConverter.FromUnstructured now handles converting integer fields to typed float values ([#93250](https://github.com/kubernetes/kubernetes/pull/93250), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

### Bug or Regression

- Fix missing delete events on informer re-lists to ensure all delete events are correctly emitted and using the latest known object state, so that all event handlers and stores always reflect the actual apiserver state as best as possible ([#115901](https://github.com/kubernetes/kubernetes/pull/115901), [@odinuge](https://github.com/odinuge)) [SIG API Machinery]

* Fix a scheduler panic due to internal cache inconsistency ([#71063](https://github.com/kubernetes/kubernetes/pull/71063), [@Huang-Wei](https://github.com/Huang-Wei))
* apiserver: fixes handling and logging of panics in REST handlers to prevent crashes ([#71076](https://github.com/kubernetes/kubernetes/pull/71076), [@liggitt](https://github.com/liggitt))

- Changed how the API server handles updates to `.spec.defaultBackend` of Ingress objects.
