## Changelog since v1.15.6

### Other notable changes

* Change GCP ILB firewall names to contain the "k8s-fw-" prefix like the rest of the firewall rules. This is needed for consistency and also for other components to identify the firewall rule as k8s/service-controller managed. ([#84622](https://github.com/kubernetes/kubernetes/pull/84622), [@prameshj](https://github.com/prameshj))

* On AttachDetachController node status update, do not retry when node doesn't exist but keep the node entry in cache. ([#50806](https://github.com/kubernetes/kubernetes/pull/50806), [@verult](https://github.com/verult))
* Prevent unneeded endpoint updates ([#50934](https://github.com/kubernetes/kubernetes/pull/50934), [@joelsmith](https://github.com/joelsmith))

ext` as appropriate.
  
  `PollWithContext(Cancel|Deadline)` will no longer return `ErrWaitTimeout` - use the `Interrupted(error) bool` helper to replace checks for `err == ErrWaitTimeout`, or compare specifically to context errors as needed. A future release will make the `ErrWaitTimeout` error private and callers must use `Interrupted()` instead. If you are returning `ErrWaitTimeout` from your own methods, switch to creating a location specific `cause err` and pass it to the new method...

### **CLI**

*   Swagger 1.2 validation is removed for kubectl. The options `--use-openapi` and `--schema-cache-dir` are also removed because they are no longer needed. ([#53232](https://github.com/kubernetes/kubernetes/pull/53232),[ @apelisse](https://github.com/apelisse))

### **Cluster Lifecycle**

  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`

be full of soup.

  `There's certainly too much pepper in that soup!' Alice said to
herself, as well as she could for sneezing.

  There was certainly too much of it in the air.  Even the
Duchess sneezed occasionally; and as for the baby, it was
sneezing and howling alternately without a moment's pause.  The
only things in the kitchen that did not sneeze, were the cook,

- Kubeadm: fixed a bug when performing validation on `ClusterConfiguration` networking fields. ([#112751](https://github.com/kubernetes/kubernetes/pull/112751), [@SataQiu](https://github.com/SataQiu))
- Kubeadm: when a sub command is needed but not provided for a kubeadm command, print a help screen instead of showing a short message. ([#111277](https://github.com/kubernetes/kubernetes/pull/111277), [@chymy](https://github.com/chymy))

* Support graceful termination with IPVS when deleting a service ([#71895](https://github.com/kubernetes/kubernetes/pull/71895), [@lbernail](https://github.com/lbernail))
* Include CRD for BGPConfigurations, needed for calico 2.x to 3.x upgrade. ([#71868](https://github.com/kubernetes/kubernetes/pull/71868), [@satyasm](https://github.com/satyasm))
