- Dockershim security: pod sandbox now always run with `no-new-privileges` and `runtime/default` seccomp profile
  dockershim seccomp: custom profiles can now have smaller seccomp profiles when set at pod level ([#90948](https://github.com/kubernetes/kubernetes/pull/90948), [@pjbgf](https://github.com/pjbgf)) [SIG Node]

- Added "general", "baseline", and "restricted" debugging profiles for kubectl debug. ([#114280](https://github.com/kubernetes/kubernetes/pull/114280), [@sding3](https://github.com/sding3)) [SIG CLI]
- Added "netadmin" debugging profiles for kubectl debug. ([#115712](https://github.com/kubernetes/kubernetes/pull/115712), [@wedaly](https://github.com/wedaly)) [SIG CLI]

  - Kube-scheduler can run more than one scheduling profile. Given a pod, the profile is selected by using its `.spec.schedulerName`. ([#88285](https://github.com/kubernetes/kubernetes/pull/88285), [@alculquicondor](https://github.com/alculquicondor)) [SIG Apps, Scheduling and Testing]

- Allowed `ImageVolume` for Restricted PSA profiles. ([#130394](https://github.com/kubernetes/kubernetes/pull/130394), [@Barakmor1](https://github.com/Barakmor1))

- `AppArmor` profiles specified in the Pod or container `SecurityContext` were no longer copied to deprecated `AppArmor` annotations (prefix `container.apparmor.security.beta.kubernetes.io/`). Anything that inspected the deprecated annotations must be migrated to use...

* Start synchronizing pods after network is ready.  ([#68752](https://github.com/kubernetes/kubernetes/pull/68752), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
* kubectl has gained new --profile and --profile-output options to output go profiles ([#68681](https://github.com/kubernetes/kubernetes/pull/68681), [@dlespiau](https://github.com/dlespiau))

- Users can traverse all the pods that are in the scheduler and waiting in the permit stage through method `IterateOverWaitingPods`. In other words,  all waitingPods in scheduler can be obtained from any profiles. Before this commit, each profile could only obtain waitingPods within that profile.

- Record requests rejected with 429 in the apiserver_request_total metric ([#108927](https://github.com/kubernetes/kubernetes/pull/108927), [@wojtek-t](https://github.com/wojtek-t))
- Removed validation if AppArmor profiles are loaded on the local node. This should be handled by the container runtime. ([#97966](https://github.com/kubernetes/kubernetes/pull/97966), [@saschagrunert](https://github.com/saschagrunert))

With cluster-wide seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there...
