- `kube-proxy` now has a new nftables-based mode, available by running
  
      `kube-proxy --feature-gates NFTablesProxyMode=true --proxy-mode nftables`
  
  This is currently an alpha-level feature and while it probably will not
  eat your data, it may nibble at it a bit. (It passes e2e testing but has
  not yet seen real-world use.)
