* CSI detach timeout increased from 10 seconds to 2 minutes ([#84321](https://github.com/kubernetes/kubernetes/pull/84321), [@cduchesne](https://github.com/cduchesne))
* Update to use go1.12.12 ([#84064](https://github.com/kubernetes/kubernetes/pull/84064), [@cblecker](https://github.com/cblecker))

- Added a mechanism that calculates a digest of etcd and the watch cache every 5 minutes and exposes it as the `apiserver_storage_digest` metric.

* TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. ([#63999](https://github.com/kubernetes/kubernetes/pull/63999), [@mikedanese](https://github.com/mikedanese))

and "unreachable" using `NoExecute` taints. In combination with `tolerationSeconds` described below, this allows per-pod specification of how long to remain bound to a node that becomes unreachable or not ready, rather than using the default of 5 minutes. You can enable this alpha feature by including `TaintBasedEvictions=true` in `--feature-gates`, such as `--feature-gates=FooBar=true,TaintBasedEvictions=true`.

### Bug or Regression

- Kubeadm: fixed the bug where the v1beta4 Timeouts.EtcdAPICall field was not respected in etcd client operations, and the default timeout of 2 minutes was always used.

### Other (Cleanup or Flake)

* Fixes bug in DaemonSetController causing it to stop processing some DaemonSets for 5 minutes after node removal. ([#76060](https://github.com/kubernetes/kubernetes/pull/76060), [@krzysztof-jastrzebski](https://github.com/krzysztof-jastrzebski))
