The scheduling hints allow the scheduler to only retry scheduling a Pod
  that was previously rejected by the NodeSchedulable plugin if a new Node or a Node update sets .spec.unschedulable to false. ([#122334](https://github.com/kubernetes/kubernetes/pull/122334), [@carlory](https://github.com/carlory)) [SIG Scheduling]
- Kube-scheduler implements scheduling hints for the PodTopologySpread plugin.

- Fixed a 1.27 scheduling regression that PostFilter plugin may not function if previous PreFilter plugins return Skip ([#119942](https://github.com/kubernetes/kubernetes/pull/119942), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]

- Fix a bug that Pods with topologySpreadConstraints get scheduled to nodes without required labels. ([#95883](https://github.com/kubernetes/kubernetes/pull/95883), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]

- Kube-scheduler implements scheduling hints for the NodeAffinity plugin.
  The scheduling hints allow the scheduler to only retry scheduling a Pod
  that was previously rejected by the NodeAffinity plugin if a new Node or a Node update matches the Pod's node affinity. ([#119155](https://github.com/kubernetes/kubernetes/pull/119155), [@carlory](https://github.com/carlory)) [SIG Scheduling]

- New default scheduling plugins order reduces scheduling and preemption latency when taints and node affinity are used ([#95539](https://github.com/kubernetes/kubernetes/pull/95539), [@soulxu](https://github.com/soulxu)) [SIG Scheduling]

- Fixed a 1.26 regression scheduling bug by ensuring that preemption is skipped when a PreFilter plugin returns `UnschedulableAndUnresolvable` ([#119952](https://github.com/kubernetes/kubernetes/pull/119952), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

- The legacy scheduler policy config is removed in v1.23, the associated flags policy-config-file, policy-configmap, policy-configmap-namespace and use-legacy-policy-config are also removed. Migrate to Component Config instead, see https://kubernetes.io/docs/reference/scheduling/config/ for details. (#105424, @kerthcet) [SIG Scheduling and Testing]

- Fix: ignore the case when updating Azure tags (#104686, @nilo19) [SIG Cloud Provider]
- Revert PR #102925 which introduced unexpected scheduling behavior based on balanced resource allocation (#105238, @damemi) [SIG Scheduling]
- Updates golang.org/x/text to v0.3.6 to fix CVE-2020-28852 (#102601, @jonesbr17) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]

- NodeInclusionPolicy in podTopologySpread plugin is enabled by default. ([#113500](https://github.com/kubernetes/kubernetes/pull/113500), [@kerthcet](https://github.com/kerthcet)) [SIG API Machinery, Apps, Scheduling and Testing]
