* 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...

* /test/e2e/framework: Adds a flag "non-blocking-taints" which allows tests to run in environments with tainted nodes. String value should be a comma-separated list. ([#81043](https://github.com/kubernetes/kubernetes/pull/81043), [@johnSchnake](https://github.com/johnSchnake))...

narrow, to be sure; but I THINK I can kick a little!'

  She drew her foot as far down the chimney as she could, and
waited till she heard a little animal (she couldn't guess of what
sort it was) scratching and scrambling about in the chimney close
above her:  then, saying to herself `This is Bill,' she gave one
sharp kick, and waited to see what would happen next.

  The first thing she heard was a general chorus of `There goes

* The calico-node addon tolerates all NoExecute and NoSchedule taints by default. So Calico components can even be scheduled on tainted nodes. ([#57122](https://github.com/kubernetes/kubernetes/pull/57122), [@caseydavenport](https://github.com/caseydavenport))

- Fixed bug where dry run message was not printed when running `kubectl label` with `--dry-run` flag. ([#111571](https://github.com/kubernetes/kubernetes/pull/111571), [@brianpursley](https://github.com/brianpursley))

* 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...

- Fix `kubectl set env` or `resources` not working for initcontainers. ([#101669](https://github.com/kubernetes/kubernetes/pull/101669), [@carlory](https://github.com/carlory))
- Fix `kubectl` alpha debug node does not work on tainted(NoExecute) nodes and tolerate everything. ([#98431](https://github.com/kubernetes/kubernetes/pull/98431), [@wawa0210](https://github.com/wawa0210))

### **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`

* [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))
