- The alpha feature `ServiceAccountIssuerDiscovery` enables publishing OIDC discovery information and service account token verification keys at `/.well-known/openid-configuration` and `/openid/v1/jwks` endpoints by API servers configured to issue service account tokens.

   * Enabled VXLAN and IP_SET config options in kernel to support some networking tools (ebtools)
   * OpenSSL CVE fixes
* ContainerVm/GCI image: try to use ifdown/ifup if available ([#33595](https://github.com/kubernetes/kubernetes/pull/33595), [@freehan](https://github.com/freehan))

### Auth

- Fixed OpenID Connect (OIDC) token refresh when the client secret contains a special character. ([#76914](https://github.com/kubernetes/kubernetes/pull/76914), [@tsuna](https://github.com/tsuna))

* Support whitespace in command path for gcp auth plugin ([#41653](https://github.com/kubernetes/kubernetes/pull/41653), [@jlowdermilk](https://github.com/jlowdermilk))
* client-go no longer imports GCP OAuth2 and OpenID Connect packages by default. ([#41532](https://github.com/kubernetes/kubernetes/pull/41532), [@ericchiang](https://github.com/ericchiang))

- The `--bind-address` parameter in kube-proxy is misleading, no port is opened with this address. Instead it is translated internally to "nodeIP". The nodeIPs for both families are now taken from the Node object if `--bind-address` is unspecified or set to the "any" address (0.0.0.0 or ::). It is recommended to leave `--bind-address`...

- kubeadm: removed preflight check for nsenter on Linux nodes
  kubeadm: added preflight check for `losetup` on Linux nodes. It's required by kubelet for keeping a block device opened. ([#129450](https://github.com/kubernetes/kubernetes/pull/129450), [@carlory](https://github.com/carlory)) [SIG Cluster Lifecycle]

* The CSIBlockVolume feature gate is now beta, and defaults to enabled. ([#74909](https://github.com/kubernetes/kubernetes/pull/74909), [@bswartz](https://github.com/bswartz))

- Kube-proxy health check ports used to listen to `:<port>` for each of the services. This is not needed and opens ports in addresses the cluster user may not have intended. The PR limits listening to all node address which are controlled by `--nodeport-addresses` flag. if no addresses are provided then we default to existing behavior by listening to `:<port>`...

        `Dataset.output_{types,shapes,classes}`.
    *   Make `num_parallel_calls` of `tf.data.Dataset.interleave` and
        `tf.data.Dataset.map` work in Eager mode.
*   Toolchains
    *   Fixed OpenSSL compatibility by avoiding `EVP_MD_CTX_destroy`.
    *   Added bounds checking to printing deprecation warnings.
    *   Upgraded CUDA dependency to 10.0
