* Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB. ([#83261](https://github.com/kubernetes/kubernetes/pull/83261), [@liggitt](https://github.com/liggitt))...

            file existence, etc.), Maven now supports a powerful condition-based activation
            through the {@code condition} field. This new mechanism allows for more flexible

    * - gcr.io/google-containers/kube-addon-manager
    * - gcr.io/google-containers/kube-dnsmasq-amd64
* - Disable thin_ls due to excessive iops ([#43113](https://github.com/kubernetes/kubernetes/pull/43113), [@dashpole](https://github.com/dashpole))
    * - Ignore .mount cgroups, fixing dissappearing stats
    * - Fix wc goroutine leak

- Capped nf_conntrack_max to 1,048,576 to prevent excessive memory consumption on high-core machines when using automatic calculation. ([#137002](https://github.com/kubernetes/kubernetes/pull/137002), [@kairosci](https://github.com/kairosci)) [SIG Apps and Network]

- **Overhauled metrics**: Kubernetes has previously made extensive use of a global metrics registry to register metrics to be exposed. By implementing a metrics registry, metrics are registered in more transparent means. Previously, Kubernetes metrics have been excluded from any kind of stability requirements.

* A pod’s Quality of Service Class is now available in its Status.
* Upgrade cAdvisor library to v0.25.0. Notable changes include,
  - Container filesystem usage tracking disabled for device mapper due to excessive
    IOPS.
  - Ignore `.mount` cgroups, fixing disappearing stats.
* A new field `terminationMessagePolicy` has been added to containers that allows

- Reduced excessive logging in the Volume Binding scheduler plugin by lowering the verbosity of high-frequency messages from `V(4)` to `V(5)`. ([#132840](https://github.com/kubernetes/kubernetes/pull/132840), [@ppmechlinski](https://github.com/ppmechlinski)) [SIG Autoscaling,...

- Reduced the number of cloud API calls and service downtime caused by excessive re-configurations of cluster LBs with externalTrafficPolicy=Local when node readiness changes (https://github.com/kubernetes/kubernetes/issues/111539). The service controller (in cloud-controller-manager) will avoid resyncing nodes which are transitioning...

- Fixed a bug where improper storage and comparison of endpoints led to excessive API traffic from the endpoints controller ([#94112](https://github.com/kubernetes/kubernetes/pull/94112), [@damemi](https://github.com/damemi)) [SIG Apps, Network and Testing]
