- **[beta]** [Node affinity/anti-affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/) and **[beta]** [pod affinity/anti-affinity](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/). Node affinity/anti-affinity allow you to specify rules for restricting which node(s) a pod can schedule onto, based on the labels on the node. Pod affinity/anti-affinity allow you to specify rules for spreading and packing pods relative...

among the schedulers for each pod. Documentation is [here](http://kubernetes.io/docs/admin/multiple-schedulers.md), design doc is [here](docs/proposals/multiple-schedulers.md).
  * More expressive node affinity syntax, and support for “soft” node affinity.
Node selectors (to constrain pods to schedule on a subset of nodes) now support

* 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))

### 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.
