* Cloud Controller Manager now sets Node.Spec.ProviderID ([#50730](https://github.com/kubernetes/kubernetes/pull/50730), [@andrewsykim](https://github.com/andrewsykim))
* Parameterize session affinity timeout seconds in service API for Client IP based session affinity. ([#49850](https://github.com/kubernetes/kubernetes/pull/49850), [@m1093782566](https://github.com/m1093782566))

* Disable session affinity for internal kubernetes service - Backport of [#56690](https://github.com/kubernetes/kubernetes/pull/56690) to 1.10 release branch ([#65177](https://github.com/kubernetes/kubernetes/pull/65177), [@afritzler](https://github.com/afritzler))

### Storage Capacity Tracking

- Fixed #118052: nodeAffinity on pods can change prior to scheduling gates being removed even when podSpec.affinity is nil in the initial spec, this matches the 1.28 behavior to allow consistent integrators to be written.

### SIG-scheduling

SIG Scheduling development efforts have been primarily focused on improving performance and reliability of the scheduler.
- Performance of the inter-pod affinity/anti-affinity feature is improved over 100X via algorithmic optimization.

* Fix inter-pod anti-affinity check to consider a pod a match when all the anti-affinity terms match. ([#62715](https://github.com/kubernetes/kubernetes/pull/62715), [@bsalamat](https://github.com/bsalamat))

- User can now use component config to configure NodeLabel plugin for the scheduler framework. ([#84297](https://github.com/kubernetes/kubernetes/pull/84297), [@liu-cong](https://github.com/liu-cong))
- Optimize inter-pod affinity preferredDuringSchedulingIgnoredDuringExecution type, up to 4x in some cases. ([#84264](https://github.com/kubernetes/kubernetes/pull/84264), [@ahg-g](https://github.com/ahg-g))
