- Kubeadm: only taint control plane nodes when the legacy "master" taint is present. This avoids the bug where "kubeadm upgrade" will re-taint a control plane  node with the new "control plane" taint even if the user explicitly untainted the node.

- DRA device taints: `DeviceTaintRule` status provides information about the rule, including whether Pods still need to be evicted (`EvictionInProgress` condition). The newly added `None` effect can be used to preview what a `DeviceTaintRule` would do if it used the `NoExecute` effect and to taint devices (`device health`) without immediately affecting scheduling or running Pods. ([#134152](https://gith...

- DRA DeviceTaintRules: the TimeAdded of the taint is not only added automatically, it now also gets updated automatically when changing the effect. ([#137167](https://github.com/kubernetes/kubernetes/pull/137167), [@pohly](https://github.com/pohly)) [SIG API Machinery, Node and Testing]

- E2e framework: the `node-role.kubernetes.io/master` taint has been removed from the default value of `--non-blocking-taints` flag. You may need to set `--non-blocking-taints` explicitly if the cluster to be tested has nodes with the deprecated `node-role.kubernetes.io/master` taint.

- Kubeadm: removed the toleration for the `node-role.kubernetes.io/master` taint from the CoreDNS deployment of `kubeadm`. With the 1.25 release of kubeadm the taint `node-role.kubernetes.io/master` is no longer applied to control plane nodes and the toleration for it can be removed with the release of 1.26. You can also perform the same toleration removal from your own...

- DRA: Device taints enable DRA drivers or admins to mark device as unusable, which prevents allocating them. Pods may also get evicted at runtime if a device becomes unusable, depending on the severity of the taint and whether the claim tolerates the taint.

* [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))
