 - PersistentVolumes have a new LastPhaseTransitionTime field which holds a timestamp of when the volume last transitioned its phase. ([#116469](https://github.com/kubernetes/kubernetes/pull/116469), [@RomanBednar](https://github.com/RomanBednar)) [SIG API Machinery, Apps, Auth, Node, Release, Storage and Testing]
 - Promoted API groups `ValidatingAdmissionPolicy` and `ValidatingAdmissionPolicyBinding` to `v1beta1`. ([#118644](https://github.com/kubernetes/kubernetes/pull/118644), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery, Apps and Testing]
 - Promoted the feature gate `ValidtaingAdmissionPolicy` to beta and it is turned off by default.

-- When --feature-gates=KMSv2KDF=true, KMS v2 uses a key derivation function to generate single use data encryption keys from a secret seed.  This eliminates the need for a counter based nonce while avoiding nonce collision concerns associated with AES-GCM's 12 byte nonce.  This behavior is off by default in v1.28, and will be enabled and locked to true in v1.29.

+- Changed how KMS v2 encryption at rest can generate data encryption keys. When you enable the `KMSv2KDF` feature gate (off by default), KMS v2 uses a key derivation function to generate single use data encryption keys from a secret seed combined with some random data.  This eliminates the need for a counter based nonce while avoiding nonce collision concerns associated with AES-GCM's 12 byte nonce.
