- Fixed a regression in kube-proxy where it might refuse to start if given
  single-stack IPv6 configuration options on a node that has both IPv4 and
  IPv6 IPs. ([#121008](https://github.com/kubernetes/kubernetes/pull/121008), [@danwinship](https://github.com/danwinship)) [SIG Network]

	// *Node is the unique identifier (an ONAME Node) for the variable.
	// TODO: keep a single varnum map, then make all of these maps slices instead?
	vars map[ir.Node]*ssa.Value

	// fwdVars are variables that are used before they are defined in the current block.
	// This map exists just to coalesce multiple references into a single FwdRef op.
	// *Node is the unique identifier (an ONAME Node) for the variable.

- Kubeadm: during the preflight check "CreateJob" of "kubeadm upgrade", check if there are no nodes where a Pod can schedule. If there are none, show a warning and skip this preflight check. This can happen in single node clusters where the only node was drained.

  - A server-side apply request that changes an object which has duplicate items in a keyed list, and modifies the duplicated item removes the duplicates and replaces them with the single item contained in the server-side apply request.

Now, instead of using independent `startup` and `shutdown` events, you can define that logic in a single function with `yield` decorated with `@asynccontextmanager` (an async context manager).

For example:

```Python
from contextlib import asynccontextmanager

from fastapi import FastAPI
