* A new `TaintNodesByCondition` admission plugin taints newly created Node objects as "not ready", to fix a race condition that could cause pods to be scheduled on new nodes before their taints were updated to accurately reflect their reported conditions. This admission plugin is enabled by default if the `TaintNodesByCondition` feature is enabled. ([#73097](https://gi...

In addition, the NodeRestriction admission plugin now prevents kubelets from modifying taints on their Node API objects, making it easier to keep track of which nodes should be in use.

### SIG CLI

  * You can remove the "old" taints (stored internally as annotations) at any time after the upgrade by doing `kubectl annotate nodes <node name> scheduler.alpha.kubernetes.io/taints-` (note the minus at the...

### **Scheduling**

*   Taint key `unreachable` is now in GA.
*   Taint key `notReady` is changed to `not-ready`, and is also now in GA.
*   These changes are automatically updated for taints. Tolerations for these taints must be updated manually. Specifically, you must:
    *   Change `node.alpha.kubernetes.io/notReady` to `node.kubernetes.io/not-ready`

* Fixed NoTaintMaster to remove master taint and keep all other applied taints.  ([#64986](https://github.com/kubernetes/kubernetes/pull/64986), [@ashleyschuett](https://github.com/ashleyschuett))

  // NodeTaintsPolicy indicates how we will treat node taints when calculating
  // pod topology spread skew. Options are:
  // - Honor: nodes without taints, along with tainted nodes for which the incoming pod
  // has a toleration, are included.
  // - Ignore: node taints are ignored. All nodes are included.

The key updated docs are:

* Python Types Intro:

  - Subtract DaemonSet pods' requests from node allocatable in the denominator while computing node utilization
  - Include taints by condition when determining if a node is unready/still starting
  - Fix `update-vendor.sh` to work on OSX and zsh
  - Add best-effort eviction for DaemonSet pods while scaling down non-empty nodes
  - Add build support for ARM64
  
  ### AliCloud

* [alpha] Users can now add taints to nodes by condition ([design doc](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/taint-node-by-condition.md))
