### **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`

   * Highly specific magic matches get a high priority
   * General magic matches which could trigger a false-positive need
     a low one
   * The priority for containers normally need to be higher than for
     the things they contain, so they don't accidently get detected
     as what's in them
   * For logic too complex to be expressed in a magic match, do the best

* fixed foreground deletion of podtemplates ([#60683](https://github.com/kubernetes/kubernetes/pull/60683), [@nilebox](https://github.com/nilebox))
* Timeout docker queries to prevent node going NotReady indefinitely. ([#56967](https://github.com/kubernetes/kubernetes/pull/56967), [@jsravn](https://github.com/jsravn))

- Fixed node reporting "notReady" with the reason 'container runtime status check may not have completed yet' after kubelet restart. ([#124430](https://github.com/kubernetes/kubernetes/pull/124430), [@AllenXu93](https://github.com/AllenXu93))

* Fix [transition between NotReady and Unreachable taints](https://github.com/kubernetes/kubernetes/issues/43444). ([#44042](https://github.com/kubernetes/kubernetes/pull/44042), [@gmarek](https://github.com/gmarek))

         * however I can't seem to get a good last modified time from

* Fixes a bug where if an error was returned that was not an `autorest.DetailedError` we would return `"not found", nil` which caused nodes to go to `NotReady` state. ([#57484](https://github.com/kubernetes/kubernetes/pull/57484), [@brendandburns](https://github.com/brendandburns))
