### Bug or Regression

- Fixes a race condition in the iptables mode of kube-proxy in 1.27 and later
  that could result in some updates getting lost (e.g., when a service gets a
  new endpoint, the rules for the new endpoint might not be added until
  much later). ([#122757](https://github.com/kubernetes/kubernetes/pull/122757), [@hakman](https://github.com/hakman)) [SIG Network]
