* A buffered audit backend can be used with other audit backends. ([#60076](https://github.com/kubernetes/kubernetes/pull/60076), [@crassirostris](https://github.com/crassirostris))

- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses.

    * }
    * If excludeMasterFromStandardLB is not set, it will be default to true, which means master nodes are excluded to the backend of standard LB.
    * Also note standard load balancer doesn't work with annotation `service.beta.kubernetes.io/azure-load-balancer-mode`. This is because all nodes (except master) are added as the LB backends.

  - `spec.backend` -> `spec.defaultBackend`
  - `serviceName` -> `service.name`
  - `servicePort` -> `service.port.name` (for string values)
  - `servicePort` -> `service.port.number` (for numeric values)
  - `pathType` no longer has a default value in v1; "Exact", "Prefix", or "ImplementationSpecific" must be specified

  Other Ingress API updates:
  - backends can now be resource or service backends

  The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code.
