As far as platforms, working with SIG-Windows, enhancements were made to the kubelet to improve platform support on Windows operating systems, and improvements to resource management were also made.  In particular, support for sysctls on Linux graduated to beta.

### SIG OpenStack

For the 1.13 release, SIG API Machinery is happy to announce that the [dry-run functionality](https://kubernetes.io/docs/reference/using-api/api-concepts/#dry-run) is now beta.

### Tools. Commonizer

- [`KT-59302`](https://youtrack.jetbrains.com/issue/KT-59302) Commonizer: make sure that opt-in annotation generated by cinterop made it into commonized artifact
- [`KT-62028`](https://youtrack.jetbrains.com/issue/KT-62028) False positive "Unnecessary '`@OptIn`' Annotation" for ExperimentalForeignApi

  - `timeout` default changed from `30s` to `10s` for v1
  - `sideEffects` default value is removed, and the field made required, and only `None` and `NoneOnDryRun` are permitted for v1
  - `admissionReviewVersions` default value is removed and the field made required for v1 (supported versions for AdmissionReview are `v1` and `v1beta1`)

supports node proxying, which allows clients of kube-apiserver to access endpoints of a Kubelet to establish connections to Pods, retrieve container logs, and more. While Kubernetes already validates the proxying address for Nodes, a bug in kube-apiserver made it possible to bypass this validation. Bypassing this validation could allow authenticated requests destined for Nodes to be redirected to the API Server through its private network.

The merged fix enforces validation against the proxying...

- Fixes a regression in the pod binding subresource to honor the `metadata.uid` precondition.
  This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. ([#116776](https://github.com/kubernetes/kubernetes/pull/116776), [@alculquicondor](https://github.com/alculquicondor)) [SIG API Machinery and Testing]

  - Add support for `--cloud-config`
  - Update group identifier to use for Cluster API annotations
  
  ### Exoscale
  - Add support for Exoscale
  
  ### GCE
  - Decrease the number of GCE Read Requests made while deleting nodes
  - Base pricing of custom instances on their instance family type
  - Add pricing information for missing machine types
  - Add pricing information for different GPU types
