- Promoted the `EnvFiles` feature gate to beta and is enabled by default. Additionally, the syntax specification for environment variables has been restricted to a subset of POSIX shell syntax (all variable values must be wrapped in single quotes).

### ConfigMap
* Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding `optional: true` to the volume or environment variable source specifications.

- Added authorization check support to the CEL expressions of ValidatingAdmissionPolicy via a `authorizer`

 - Fixed the behavior of the `KUBE_PROXY_NFTABLES_SKIP_KERNEL_VERSION_CHECK` environment variable in the nftables proxier. The kernel version check is now skipped only when this variable is explicitly set to a non-empty value. To skip the check, set the `KUBE_PROXY_NFTABLES_SKIP_KERNEL_VERSION_CHECK` environment variable.

* `hack/local-up-cluster.sh` now enables the Node authorizer by default. Authorization modes can be overridden with the `AUTHORIZATION_MODE` environment variable, and the `ENABLE_RBAC` environment variable is no longer used.
