- In a future release, kubelet will no longer create the CSI NodePublishVolume target directory, in accordance with the CSI specification. CSI drivers may need to be updated accordingly to properly create and process the target path. ([#75535](https://github.com/kubernetes/kubernetes/issues/75535)) [SIG Storage]

#### kube-proxy:

* Add MAX_PODS_PER_NODE env so that GCE/GKE user can use it to specify the default max pods per node for the cluster. IP_ALIAS_SIZE will be changed accordingly. Must have ip alias enabled. ([#63621](https://github.com/kubernetes/kubernetes/pull/63621), [@grayluck](https://github.com/grayluck))

* Add MAX_PODS_PER_NODE env so that user can use it to specify the default max pods per node for the cluster. IP_ALIAS_SIZE will be changed accordingly. Must have ip alias enabled. ([#63466](https://github.com/kubernetes/kubernetes/pull/63466), [@grayluck](https://github.com/grayluck))

- ACTION REQUIRED for custom scheduler plugin developers:
  `EventsToRegister` in the `EnqueueExtensions` interface gets `ctx` in the parameters and `error` in the return values.
  Please change your plugins' implementation accordingly. ([#126113](https://github.com/kubernetes/kubernetes/pull/126113), [@googs1025](https://github.com/googs1025)) [SIG Node, Scheduling, Storage and Testing]

- Relaxed API validation for usage `key encipherment` and `kubelet` uses requested usages accordingly ([#111660](https://github.com/kubernetes/kubernetes/pull/111660), [@pacoxu](https://github.com/pacoxu))

and the value <code>1.1</code> is represented as a <code>float32</code> or a <code>float64</code>
depending on the type argument for <code>f</code>.
Accordingly, if <code>f</code> is instantiated with a <code>float32</code> type,
the numeric value of the expression <code>P(1.1) + 1.2</code> will be computed
with the same precision as the corresponding non-constant <code>float32</code>

  kubeadm no longer sets the node-mask automatically on IPv6 deployments, you must check that your IPv6 service subnet mask is compatible with the default node mask /64 or set it accordingly.
