* `tf.keras`
    * `Model.compile` now support `steps_per_execution='auto'` as a parameter, allowing automatic tuning of steps per execution during `Model.fit`,
    `Model.predict`, and `Model.evaluate` for a significant performance boost.

## Thanks to our Contributors

This release contains contributions from many people at Google, as well as:

- Etcd: Updated to v3.5.5. ([#112489](https://github.com/kubernetes/kubernetes/pull/112489), [@dims](https://github.com/dims))
- Fixed Admission controllers that caused unnecessary significant load on `apiserver'. ([#112696](https://github.com/kubernetes/kubernetes/pull/112696), [@aimuz](https://github.com/aimuz))

/opt/bin/minio` and process to perform `mc admin service restart alias/`. ### Upgrade Checklist - Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk. - Read the release notes for MinIO *before* performing any upgrade, there is no forced requirement to upgrade to latest release upon every release. Some release may not be relevant to your setup, avoid upgrading production environments unnecessarily....

### Extending Ingress with and replacing a deprecated annotation with IngressClass

### Ingress graduates to General Availability

### Azure

## Changelog since v1.21.12

## Changes by Kind

### Bug or Regression

- Correct event registration for multiple scheduler plugins; this fixes a potential significant delay in re-queueing unschedulable pods. ([#109466](https://github.com/kubernetes/kubernetes/pull/109466), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling and Testing]

### SIG Scheduling
[Pod Priority and Preemption](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/) has graduated to Beta, so it is enabled by default. Note that this involves [significant and important changes for operators](https://github.com/kubernetes/sig-release/pull/201/files). The team also worked on improved performance and reliability of the scheduler.

### SIG Storage

   * Returns x scaled by a power of 2 such that it is in the range [1, 2). Assumes x is positive,
   * normal, and finite.

  static double scaleNormalize(double x) {
    long significand = doubleToRawLongBits(x) & SIGNIFICAND_MASK;
    return longBitsToDouble(significand | ONE_BITS);
  }

  static double bigToDouble(BigInteger x) {
    // This is an extremely fast implementation of BigInteger.doubleValue(). JDK patch pending.

### SIG Scheduling

- The equivalence class cache has been redesigned to be a two level cache, resulting in a significant increase in scheduling throughput and performance. ([#65714](https://github.com/kubernetes/kubernetes/pull/65714), [@resouer](https://github.com/resouer))
