- Specific error message on failed rolling update issued by older kubectl against 1.4 master ([#32751](https://github.com/kubernetes/kubernetes/issues/32751))
- bump master cidr range from /30 to /29 ([#32886](https://github.com/kubernetes/kubernetes/issues/32886))

## Changelog since v1.5.0-alpha.1

### Action Required

* Deprecate the --reconcile-cidr kubelet flag because it has no function anymore ([#35523](https://github.com/kubernetes/kubernetes/pull/35523), [@luxas](https://github.com/luxas))

  * Add ip-masq-agent addon to the addons folder which is used in GCE if `--non-masquerade-cidr` is set to 0/0 ([#46038](https://github.com/kubernetes/kubernetes/pull/46038), [@dnardo](https://github.com/dnardo))

- Fixes connection errors when using `--volume-host-cidr-denylist` or `--volume-host-allow-local-loopback` ([#98436](https://github.com/kubernetes/kubernetes/pull/98436), [@liggitt](https://github.com/liggitt)) [SIG Network and Storage]

- KEP-1880: Users of the new feature to add multiple service CIDR will use by default a dual-write strategy on the new ClusterIP allocators to avoid the problem of possible duplicate IPs allocated to Services when running skewed kube-apiservers using different allocators. They can opt-out of this behavior by enabled...

  and removed `--short` flag entirely. ([#116720](https://github.com/kubernetes/kubernetes/pull/116720), [@soltysh](https://github.com/soltysh))
- Kube-controller-manager deprecate `--volume-host-cidr-denylist` and `--volume-host-allow-local-loopback` flags. ([#118128](https://github.com/kubernetes/kubernetes/pull/118128), [@carlory](https://github.com/carlory)) [SIG API Machinery, Apps, Network, Node, Storage and Testing]

- Added a new IPAddress object kind
  - Added a new ClusterIP allocator. The new allocator removes previous Service CIDR block size limitations for IPv4, and limits IPv6 size to a /64 ([#115075](https://github.com/kubernetes/kubernetes/pull/115075), [@aojea](https://github.com/aojea)) [SIG API Machinery, Apps, Auth, CLI, Cluster Lifecycle, Network and Testing]

* Avoid panic when failing to allocate a Cloud CIDR (aka GCE Alias IP Range).  ([#58186](https://github.com/kubernetes/kubernetes/pull/58186), [@negz](https://github.com/negz))

  have been validated.
* The following deprecated kubelet flags are removed: `--config`, `--auth-path`,
  `--resource-container`, `--system-container`, `--reconcile-cidr`
* Remove the temporary fix for pre-1.0 mirror pods. Upgrade directly from
  pre-1.0 to 1.6 kubelet is not supported.
* Fluentd was migrated to Daemon Set, which targets nodes with

- Removed the generally available feature gate `ProxyTerminatingEndpoints`. ([#122134](https://github.com/kubernetes/kubernetes/pull/122134), [@ty-dc](https://github.com/ty-dc))
