### SIG GCP

- Added tolerations for Stackdriver Logging and Metadata Agents. ([#69737](https://github.com/kubernetes/kubernetes/pull/69737), [@qingling128](https://github.com/qingling128))

* The kubelet uses a new release 3.1 of the pause container with the Docker runtime. This version will clean up orphaned zombie processes that it inherits. ([#57517](https://github.com/kubernetes/kubernetes/pull/57517), [@verb](https://github.com/verb))

## Changelog since v1.16.0

### Other notable changes

* 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))

- AppArmor profiles specified in the pod or container SecurityContext are no longer copied to deprecated AppArmor annotations (prefix `container.apparmor.security.beta.kubernetes.io/`). Anything that inspects the deprecated annotations must be migrated to use the SecurityContext fields instead. ([#131989](https://github.com/kubernetes/kubernetes/pull/131989), [@tallclair](https://github.com/tallclair)) [SIG Node]

* Restrict redirect following from the apiserver to same-host redirects, and ignore redirects in some cases. ([#66516](https://github.com/kubernetes/kubernetes/pull/66516), [@tallclair](https://github.com/tallclair))
