#### 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))

    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.
  

- Namespace editors and admins can now create leases.coordination.k8s.io and should use this type for leaderelection instead of configmaps. ([#111515](https://github.com/kubernetes/kubernetes/pull/111515), [@deads2k](https://github.com/deads2k)) [SIG API Machinery and Auth]

* 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))

- Client-go: Optimized leaders renewing leases by updating leader lock optimistically without getting the record from the API server first. Also, a new metric `leader_election_slowpath_total` was added to allow users to monitor how many leader elections are updated non-optimistically.
