### Promoted CRD Validation Expression Language to Beta

* Fix a scalability issue where high rates of event writes degraded etcd performance. ([#64539](https://github.com/kubernetes/kubernetes/pull/64539), [@ccding](https://github.com/ccding))

- The in-tree cloud provider for vSphere has been deprecated and removed. Users are advised to utilize the external cloud provider and CSI driver available at https://github.com/kubernetes/cloud-provider-vsphere. ([#122937](https://...

    caused by looking up CA certificates. This is now fixed.


## Version 3.1.0

_2016-02-06_

 *  New: WebSockets now defer some writes. This should improve performance for
    some applications.
 *  New: Override `equals()` and `hashCode()` in our new cookie class. This
    class now defines equality by value rather than by reference.
