## 0.93.0

### Features

* ✨ Add support for `lifespan` async context managers (superseding `startup` and `shutdown` events). Initial PR [#2944](https://github.com/tiangolo/fastapi/pull/2944) by [@uSpike](https://github.com/uSpike).

Now, instead of using independent `startup` and `shutdown` events, you can define that logic in a single function with `yield` decorated with `@asynccontextmanager` (an async context manager).

- Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. ([#88953](https://github.com/kubernetes/kubernetes/pull/88953), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]

- Moved `non-graceful node` shutdown to GA. ([#118228](https://github.com/kubernetes/kubernetes/pull/118228), [@carlory](https://github.com/carlory))

  - `disable-force-detach` (defaults to `false`): Prevent force detaching volumes based on maximum unmount time and node status. If enabled, the non-graceful node shutdown feature must be used to recover from node failure (see https://kubernetes.io/blog/2023/08/16/kubernetes-1-28-non-graceful-node-shutdown-ga/). If enabled and a pod must be forcibly terminated at the risk of corruption, then the appropriate VolumeAttachment object (see here: https://kubernetes.io/docs/reference/ku...

- Promoted Linux node pressure stall information (PSI) metrics to beta. ([#132822](https://github.com/kubernetes/kubernetes/pull/132822), [@roycaihw](https://github.com/roycaihw)) [SIG Node]
- Promoted Windows graceful shutdown feature from alpha to beta. ([#133062](https://github.com/kubernetes/kubernetes/pull/133062), [@zylxjtu](https://github.com/zylxjtu))

- Fixed graceful apiserver shutdown to not drop outgoing bytes before the process terminates. ([#72970](https://github.com/kubernetes/kubernetes/pull/72970), [@sttts](https://github.com/sttts))

### Apps

- Fixed an error with stuck informers when an etcd watch receives update or delete events with missing data. ([#76675](https://github.com/kubernetes/kubernetes/pull/76675), [@ryanmcnamara](https://github.com/ryanmcnamara))
- `DelayingQueue.ShutDown()` can now be invoked multiple times without causing a closed channel panic. ([#77170](https://github.com/kubernetes/kubernetes/pull/77170), [@smarterclayton](https://github.com/smarterclayton))

- Cel: converting a quantity value into a quantity value failed. ([#123669](https://github.com/kubernetes/kubernetes/pull/123669), [@pohly](https://github.com/pohly))
- Client-go/tools/record.Broadcaster: Fixed automatic shutdown on WithContext cancellation. ([#124635](https://github.com/kubernetes/kubernetes/pull/124635), [@pohly](https://github.com/pohly))
- Do not remove the "batch.kubernetes.io/job-tracking" finalizer from a Pod, in a corner

* remove time waiting after create storage account (save 25s) ([#56679](https://github.com/kubernetes/kubernetes/pull/56679), [@andyzhangx](https://github.com/andyzhangx))
* Allow kubernetes components to react to SIGTERM signal and shutdown gracefully. ([#57756](https://github.com/kubernetes/kubernetes/pull/57756), [@mborsz](https://github.com/mborsz))

* Reduce time needed to attach Azure disks ([#40066](https://github.com/kubernetes/kubernetes/pull/40066), [@codablock](https://github.com/codablock))
* fixing Cassandra shutdown example to avoid data corruption ([#39199](https://github.com/kubernetes/kubernetes/pull/39199), [@deimosfr](https://github.com/deimosfr))
