- Azure cloud provider cache TTL is configurable, list of the azure cloud provider is as following:
  - "availabilitySetNodesCacheTTLInSeconds"
  - "vmssCacheTTLInSeconds"

- The in-tree cloud provider for AWS (and the EBS storage plugin) has now been removed. Please use the external cloud provider and CSI driver from https://github.com/kubernetes/cloud-provider-aws instead.

### OpenStack

SIG-OpenStack updated the OpenStack provider to use newer APIs, consolidated community code into one repository, engaged with the Cloud Provider Working Group to have a consistent plan for moving provider code into individual repositories, improved testing of provider code, and strengthened ties with the OpenStack developer community.

### API-machinery

* Deprecate auto detecting cloud providers in kubelet. Auto detecting cloud providers go against the initiative for out-of-tree cloud providers as we'll now depend on cAdvisor integrations with cloud providers instead of the core repo. In the near future, `--cloud-provider` for kubelet will either be an empty string or `external`.  ([#51312](https://github.com/kubernetes/kubernetes/pull/51312), [@and...

SIG-VMware development was primarily focused on fixing bugs for the in-tree cloud provider, starting the development of the external cloud provider and taking ownership of the cluster-api provider for vSphere.

In-tree cloud provider bug fixes and improvements included:
- Adding initial Zones support to the provider using vSphere Tags
- Improving the testing harness for the cloud provider by introducing vcsim for automated testing

- Fix: set nil cache entry based on old cache ([#87591](https://github.com/kubernetes/kubernetes/pull/87591), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

### SIG Cloud Provider

- [KCCM] drop filtering nodes for the providerID when syncing load balancers, but have changes to the field trigger a re-sync of load balancers. This should ensure that cloud providers which don't specify providerID, can still use the service controller implementation to provision load balancers. ([#117602](https://github.com/...
