- DRA: scheduling pods is up to 16x faster, depending on the scenario. Scheduling throughput depends a lot on cluster utilization. It is higher for lightly loaded clusters with free resources and gets lower when the cluster utilization increases.

- A new API server flag `--encryption-provider-config-automatic-reload` was added to control when the encryption config should be automatically reloaded without needing to restart the server.  All KMS plugins are now merged into a single healthz check at `/healthz/kms-providers` when reload is enabled, or when only KMS v2 plugins are used.

- Add alpha support for manifest-based admission control configuration (KEP-5793). When the `ManifestBasedAdmissionControlConfig` feature gate is enabled, admission webhooks and CEL-based policies can be loaded from static manifest files on disk via the `staticManifestsDir` field in `AdmissionConfiguration`. These policies are active from API server startup, survive etcd unavailability, and can protect API-based admission resources from modification. ([...

- Kube-apiserver: the `--encryption-provider-config` file is now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior....
