themes that guided their work.

### SIG API Machinery

[SIG API Machinery][] is responsible for all aspects of the API server: API registration and discovery, generic API CRUD semantics, admission control, encoding/decoding, conversion, defaulting, persistence layer (etcd), OpenAPI, third-party resources, garbage collection, and client libraries.

- Limit the body length of exec readiness/liveness probes. remote CRIs and Docker shim read a max of 16MB output of which the exec probe itself inspects 10kb. ([#82514](https://github.com/kubernetes/kubernetes/pull/82514), [@dims](https://github.com/dims))

- a new `EndpointSliceProxying` feature gate has been added to control the use of EndpointSlices in kube-proxy. The EndpointSlice feature gate that used to control this behavior no longer affects kube-proxy. This feature has been disabled by default. ([#86137](https://github.com/kubernetes/kubernetes/pull/86137), [@robscott](https://github.com/robscott)) 

#### kubeadm:

- Made `apiextensions-apiserver` binary linking static (also affects the deb and rpm packages). ([#114226](https://github.com/kubernetes/kubernetes/pull/114226), [@saschagrunert](https://github.com/saschagrunert))

    *   Change `node.alpha.kubernetes.io/notReady` to `node.kubernetes.io/not-ready`
    *   Change `node.alpha.kubernetes.io/unreachable` to  `node.kubernetes.io/unreachable`
*   The `node.kubernetes.io/memory-pressure` taint now respects the configured whitelist.  To use it, you must add it to the whitelist.([#55251](https://github.com/kubernetes/kubernetes/pull/55251),[ @deads2k](https://github.com/deads2k))

- Kubectl create service now respects namespace flag ([#101005](https://github.com/kubernetes/kubernetes/pull/101005), [@zxh326](https://github.com/zxh326)) [SIG CLI]

- kubeadm: Use `advertise-client-urls` instead of `listen-client-urls` as and `etcd-servers` options for apiserver. ([#69827](https://github.com/kubernetes/kubernetes/pull/69827), [@tomkukral](https://github.com/tomkukral))

* Code generated for CRDs now passes `go vet`. ([#62412](https://github.com/kubernetes/kubernetes/pull/62412), [@bhcleek](https://github.com/bhcleek))
* "beginPort+offset" format support for port range which affects kube-proxy only ([#58731](https://github.com/kubernetes/kubernetes/pull/58731), [@yue9944882](https://github.com/yue9944882))

  * Kube-Proxy now defaults to an iptables-based proxy. If the --proxy-mode flag is
specified while starting kube-proxy (‘userspace’ or ‘iptables’), the flag value
will be respected. If the flag value is not specified, the kube-proxy respects
the Node object annotation: ‘net.beta.kubernetes.io/proxy-mode’. If the
annotation is not specified, then ‘iptables’ mode is the default. If kube-proxy
is unable to start in iptables mode because system requirements are not met

* Job controller now respects ControllerRef to avoid fighting over Pods. ([#42176](https://github.com/kubernetes/kubernetes/pull/42176), [@enisoc](https://github.com/enisoc))
