(liveness & readiness) probes using an HTTPGetAction will no longer follow redirects to different hostnames from the original probe request. Instead, these non-local redirects will be treated as a Success (the documented behavior). In this case an event with reason "ProbeWarning" will be generated, indicating that the redirect was ignored. If you were previously relying on the redirect to run health checks against different endpoints, you will need to perform the healthcheck logic outside the Kubelet,...

* action required: Deprecate the kubelet's cadvisor port. The default will change to 0 (disabled) in 1.12, and the cadvisor port will be removed entirely in 1.13. ([#59827](https://github.com/kubernetes/kubernetes/pull/59827), [@dashpole](https...

- Kube-proxy's IPVS proxy mode no longer sets the net.ipv4.conf.all.route_localnet sysctl parameter. Nodes upgrading will have net.ipv4.conf.all.route_localnet set to 1 but new nodes will inherit the system default (usually 0). If you relied on any behavior requiring net.ipv4.conf.all.route_localnet, you must set ensure it is enabled as kube-proxy will no longer set it automatically. This change helps to further mitigate CVE-2020-8558. ([#92938](https://github.com/kubernetes/kubernetes/pull/92938),...

- GCE Internal LoadBalancer sync loop will now release the ILB IP address upon sync failure. An error in ILB forwarding rule creation will no longer leak IP addresses.

## Dependencies

    * this enables the default scheduler to bind the Pod to the target host. If node affinity
    * of DaemonSet Pod already exists, it will be replaced.
    * DaemonSet controller will only perform these operations when creating DaemonSet Pods;
    * and those operations will only modify the Pods of DaemonSet, no changes are made to the
    * `.spec.template` of DaemonSet.

#### kubelet:

- The `/debug/api_priority_and_fairness/dump_requests` path at an apiserver will no longer return a phantom line for each exempt priority level. ([#93406](https://github.com/kubernetes/kubernetes/pull/93406), [@MikeSpreitzer](https://github.com/MikeSpreitzer)) [SIG API Machinery]

    * Custom apiservers built with the latest apiserver library will have the 100MB limit on the body of resource requests as well. The limit can be altered via ServerRunOptions.MaxRequestBodyBytes.

- Pods will now post their readiness during termination. ([#110418](https://github.com/kubernetes/kubernetes/pull/110418), [@aojea](https://github.com/aojea)) [SIG Network, Node and Testing]
