* Fixed race condition issue when detaching azure disk, preventing `Multi-Attach error`s when scheduling one pod from one node to another. ([#60183](https://github.com/kubernetes/kubernetes/pull/60183), [@andyzhangx](https://github.com/andyzhangx))

- `kubectl run --env` no longer supports CSV parsing. To provide multiple environment
  variables, use the `--env` flag multiple times instead. Example: `--env ONE=1 --env TWO=2` instead of `--env ONE=1,TWO=2`.

- Removed deprecated command `kubectl stop`.

- Kubectl can now use http caching for the OpenAPI schema. The cache

  * Previously this would cause the command to fail regardless of whether or not the field was present in the object model
  * Now the command will succeed even if the sort-by field is missing from one or more of the objects

- Image garbage collection no longer fails for images with only one tag but more than one repository associated. ([#70647](https://github.com/kubernetes/kubernetes/pull/70647), [@corvus-ch](https://github.com/corvus-ch))

  Depending on the value returned from QueueingHintFn, the scheduling queue changes how it queues each Pod:
  - if more than one QueueingHintFn returns QueueImmediately, it queues Pod to activeQ.
  - If no QueueingHintFn returns QueueImmediately and more than one plugin returns QueueAfterBackoff, it queues Pod to backoffQ if Pod is backing off, or to activeQ if Pod's backoff has already finished.

- Kubenet: added HostPort IPv6 support.  HostPortManager: operates only with one IP family, failing if receives port mapping entries with different IP families.  HostPortSyncer: operates only with one IP family, skipping portmap entries with different IP families ([#80854](https://github.com/kubernetes/kubernetes/pull/80854), [@aojea](https://github.com/aojea))

<= 1.32 proceeded to schedule pods onto nodes with no devices by not allocating any devices for those pods. Kubernetes 1.33 changes that to only picking nodes which have at least one device. Users who want the "proceed with scheduling also without devices" semantic can use the upcoming prioritized list feature with one sub-request for "all" devices and a second alternative with "count: 0".

*   Metrics are added for monitoring admission plugins, including the new dynamic (webhook-based) ones. ([#55183](https://github.com/kubernetes/kubernetes/pull/55183),[ @jpbetz](https://github.com/jpbetz))

* The old dynamic client has been replaced by a new one.  The previous dynamic client will exist for one release in `client-go/deprecated-dynamic`.  Switch as soon as possible. ([#63446](https://github.com/kubernetes/kubernetes/pull/63446), [@deads2k](https://github.com/deads2k))

the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year), **and** are referenced from the `.secrets` list of a ServiceAccount object, **and**  are not referenced from pods. This label causes the authentication layer to reject use of the credentials. After being labeled as invalid, if the time specified by `--legacy-service-account-token-clean-up-period` (defaulting to one year) passes without the credential being used, the secret is automatically deleted.
