* The Categories []string field on discovered API resources represents the list of group aliases (e.g. "all") that each resource belongs to. ([#43338](https://github.com/kubernetes/kubernetes/pull/43338), [@fabianofranz](https://github.com/fabianofranz))

#### Apps

- Hyperkube short aliases have been removed from source code, because hyperkube docker image currently creates these aliases. ([#76953](https://github.com/kubernetes/kubernetes/pull/76953), [@Rand01ph](https://github.com/Rand01ph))

#### Auth

* Fixes issue where subpath readOnly mounts failed ([#63045](https://github.com/kubernetes/kubernetes/pull/63045), [@msau42](https://github.com/msau42))
* Bugfix allowing use of IP-aliases with custom-mode network in GCE setup scripts. ([#62172](https://github.com/kubernetes/kubernetes/pull/62172), [@shyamjvs](https://github.com/shyamjvs))

# v1.9.7

    
    From: [@mikedanese](https://github.com/mikedanese):
    Instead of aliasing. Aliases are annoying in a number of ways. This is
    specifically bugging me now because they make the action graph harder to
    analyze programmatically. By using aliases here, we would need to handle
    potentially aliased go_binary targets and dereference to the effective
    target.
  

- Enabled completion for aliases defined in `kubectlrc`. ([#131586](https://github.com/kubernetes/kubernetes/pull/131586), [@ardaguclu](https://github.com/ardaguclu))

* Remove deprecated kubectl command aliases 'run-container' ([#70728](https://github.com/kubernetes/kubernetes/pull/70728), [@Pingan2017](https://github.com/Pingan2017))

    * enforces  kubeadm  upgrading kubernetes from the same major and minor versions as the kubeadm binary.
* Bugfix allowing use of IP-aliases with custom-mode network in GCE setup scripts. ([#62172](https://github.com/kubernetes/kubernetes/pull/62172), [@shyamjvs](https://github.com/shyamjvs))

- Kubernetes components that perform leader election now only support using `Leases` for this. ([#114055](https://github.com/kubernetes/kubernetes/pull/114055), [@aimuz](https://github.com/aimuz))

### Bug or Regression

- Avoid GCE API calls when initializing GCE CloudProvider for Kubelets.
  Avoid unnecessary GCE API calls when adding IP alises or reflecting them in Node object in GCE cloud provider. ([#96864](https://github.com/kubernetes/kubernetes/pull/96864), [@tosi3k](https://github.com/tosi3k)) [SIG Apps, Cloud Provider and Network]
