### Canceling a Call ([.kt][CancelCallKotlin], [.java][CancelCallJava])

* Add possibility to use multiple floatingip pools in openstack loadbalancer ([#49697](https://github.com/kubernetes/kubernetes/pull/49697), [@zetaab](https://github.com/zetaab))
* The 504 timeout error was returning a JSON error body that indicated it was a 500.  The body contents now correctly report a 500 error. ([#49678](https://github.com/kubernetes/kubernetes/pull/49678), [@smarterclayton](https://github.com/smarterclayton))
