- Added `NewVolumeManagerReconstruction` feature gate and enabled it by default to enable updated discovery of mounted volumes during kubelet startup. Please watch for kubelet getting stuck at startup and / or not unmounting volumes from deleted Pods and report any issues in this area. ([#115268](https://github.com/kubernetes/kubernetes/pull/115268), [@jsafrane](https://github.com/jsafrane))

- The kube-proxy `sync_proxy_rules_iptables_total` metric has now reverted back
  to its pre-1.27 behavior of tracking the total number of iptables rules that
  kube-proxy is responsible for, rather than only counting the number of rules
  that it re-synced on the last sync. The new `sync_proxy_rules_iptables_last`
