- Feature gate `CSIMigration` was locked to enabled. `CSIMigration` is GA now. The feature gate will be removed in `v1.27`. ([#110410](https://github.com/kubernetes/kubernetes/pull/110410), [@Jiawei0227](https://github.com/Jiawei0227))

- The feature gate was mentioned as `csiMigrationRBD` where it should have been `CSIMigrationRBD` to be in parity with other migration plugins. This release correct the same and keep it as `CSIMigrationRBD`.

- a new `EndpointSliceProxying` feature gate has been added to control the use of EndpointSlices in kube-proxy. The EndpointSlice feature gate that used to control this behavior no longer affects kube-proxy. This feature has been disabled by default.

- The `DefaultIngressClass` feature is now GA. The `--feature-gate` parameter will be removed in 1.20. ([#91957](https://github.com/kubernetes/kubernetes/pull/91957), [@cmluciano](https://github.com/cmluciano)) [SIG API Machinery, Apps, Network and Testing]

* The alpha Accelerators feature gate is deprecated and will be removed in v1.11. Please use device plugins ([https://github.com/kubernetes/enhancements/issues/368](https://github.com/kubernetes/enhancements/issues/368)) instead. They can be enabled using the DevicePlugins feature gate. ([#57384](https://github.com/kubernetes/kubernetes/pull/57384), [@mindprince](https://github.com/mindprince))

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.

**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

  - The GA `PodPriority` feature gate is now on by default and cannot be disabled. The feature gate will be removed in v1.18. ([#79262](https://github.com/kubernetes/kubernetes/pull/79262), [@draveness](https://github.com/draveness))

* Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is automatically enabled if the `Initializers` admission plugin is enabled.([#51436](https://github.com/kubernetes/kubernetes/pull/51436))

* Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is auto-enabled if the `Initialzers` admission plugin is enabled. ([#51436](https://github.com/kubernetes/kubernetes/pull/51436), [@liggitt](https://github.com/liggitt))

* CRI logging and stats are now considered beta ([ref](https://github.com/kubernetes/enhancements/issues/552))
* The dynamic Kubelet config feature is now beta, and the DynamicKubeletConfig feature gate is on by default. In order to use dynamic Kubelet config, ensure that the Kubelet's --dynamic-config-dir option is set.
