* The `system-node-critical` and `system-cluster-critical` priority classes are now limited to the `kube-system` namespace by the `PodPriority` admission plugin. ([#65593](https://github.com/kubernetes/kubernetes/pull/65593), [@bsalamat](https://github.com/bsalamat))

*   Scheduler cache ignores updates to an assumed pod if updates are limited to pod annotations.  ([#54008](https://github.com/kubernetes/kubernetes/pull/54008),[ @yguo0905](https://github.com/yguo0905))

* Enable DefaultTolerationSeconds admission controller by default ([#41815](https://github.com/kubernetes/kubernetes/pull/41815), [@kevin-wangzefeng](https://github.com/kevin-wangzefeng))
* ResourceQuota ability to support default limited resources ([#36765](https://github.com/kubernetes/kubernetes/pull/36765), [@derekwaynecarr](https://github.com/derekwaynecarr))

- Fix: incorrect max azure disk max count ([#92331](https://github.com/kubernetes/kubernetes/pull/92331), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fixes a bug evicting pods after a taint with a limited tolerationSeconds toleration is removed from a node ([#93722](https://github.com/kubernetes/kubernetes/pull/93722), [@liggitt](https://github.com/liggitt)) [SIG Apps and Node]

  for a certain priority level configuration object via the two newly introduced fields `lendablePercent`, and
  `borrowingLimitPercent` located under the `.spec.limited` field of the designated priority level.
  This change added the following metrics:
    - `apiserver_flowcontrol_nominal_limit_seats`: Nominal number of execution seats configured for each priority level

- Implemented logging for failed transactions and the full table in `kube-proxy` with 
`nftables` when using log level 4 or higher. Logging is rate-limited to one entry every 24 hours 
to avoid performance issues. ([#128886](https://github.com/kubernetes/kubernetes/pull/128886), [@npinaeva](https://github.com/npinaeva))
- Implemented the `scheduler_cache_size` metric.

<code>T</code> listed in a case must implement the type of <code>x</code>.

* Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB.
