### Bug or Regression

- Client-go: resolves an issue with informers falling back to full list requests when timeouts are encountered, rather than re-establishing a watch. ([#89978](https://github.com/kubernetes/kubernetes/pull/89978), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

for a specified amount of time. As before, taints are created using `kubectl taint` (but internally they are now represented as a field `taints` in the NodeSpec rather than using the `scheduler.alpha.kubernetes.io/taints` annotation on Node). Tolerations are now specified in a new-in-1.6 `tolerations` field of the PodSpec rather than using the `scheduler.alpha.kubernetes.io/tolerations` annotation on the Pod. When you upgrade to 1.6, the scheduler will start using the fields and will ignore the annotations....

### API Change

* Prevent hotloops on error conditions, which could fill up the disk faster than log rotation can free space. ([#40497](https://github.com/kubernetes/kubernetes/pull/40497), [@lavalamp](https://github.com/lavalamp))

- `kubeadm`: will now allow deploying a kubelet that is 3 versions older than the version of `kubeadm` (N-3). This aligns with the recent change made by SIG Architecture that extends the support skew between the control plane and kubelets. Tolerate this new kubelet skew for the commands `init`, `join` and `upgrade`. Note that if the `kubeadm` user applies a control plane version that is older than the `kubeadm` version (N-1 maximum) then the skew between the kubelet and control plane...

* Fix public IP not found issues for VMSS nodes ([#80703](https://github.com/kubernetes/kubernetes/pull/80703), [@feiskyer](https://github.com/feiskyer))
* Fix a conformance test that was skipped when client had a newer micro version than server. ([#80598](https://github.com/kubernetes/kubernetes/pull/80598), [@smarterclayton](https://github.com/smarterclayton))

* Fix security holes in GCE metadata proxy. ([#51302](https://github.com/kubernetes/kubernetes/pull/51302), [@ihmccreery](https://github.com/ihmccreery))
* Fixed an issue looking up cronjobs when they existed in more than one API version ([#52227](https://github.com/kubernetes/kubernetes/pull/52227), [@liggitt](https://github.com/liggitt))

* Back porting critical vSphere bug fixes to release 1.3 ([#31993](https://github.com/kubernetes/kubernetes/pull/31993), [@dagnello](https://github.com/dagnello))
* Back port - Openstack provider allowing more than one service port for lbaas v2 ([#32001](https://github.com/kubernetes/kubernetes/pull/32001), [@dagnello](https://github.com/dagnello))

- Fixes a bug where Services using finalizers may hold onto ClusterIP and/or NodePort allocated resources for longer than expected if the finalizer is removed using the status subresource ([#120656](https://github.com/kubernetes/kubernetes/pull/120656), [@aojea](https://github.com/aojea)) [SIG Network and Testing]

* GCE provider: Create TargetPool with 200 instances, then update with rest ([#27865](https://github.com/kubernetes/kubernetes/pull/27865), [@zmerlynn](https://github.com/zmerlynn))
* GCE provider: Limit Filter calls to regexps rather than large blobs ([#27741](https://github.com/kubernetes/kubernetes/pull/27741), [@zmerlynn](https://github.com/zmerlynn))
