accurately and efficiently track set membership across `apply` operations. The format used for `ApplySet` is set out in  [KEP 3659](https://github.com/kubernetes/enhancements/issues/3659) as a low-level specification.  Other tools in the ecosystem can also build on this specification for improved interoperability.  To try the ApplySet-based pruning alpha, set `KUBECTL_APPLYSET=true` and use the flags `--prune --applyset=secret-name` with `kubectl apply`.

- Added flag `--include-uninitialized` to `kubectl annotate`, `apply`, `edit-last-applied`,
  `delete`, `describe`, `edit`, `get`, `label,` and `set`. `--include-uninitialized=true` makes
  kubectl commands apply to uninitialized objects, which by default are ignored
  if the names of the objects are not provided. `--all` also makes kubectl
  commands apply to uninitialized objects. See the

- Fixed bugs in handling of server-side apply, create, and update API requests for objects containing duplicate items in keyed lists.
  - A `create` or `update` API request with duplicate items in a keyed list no longer wipes out managedFields. Examples include env var entries with the same name, or port entries with the same containerPort in a pod spec.
