- Removed deprecated `--seccomp-profile-root`/`seccompProfileRoot` config. ([#103941](https://github.com/kubernetes/kubernetes/pull/103941), [@saschagrunert](https://github.com/saschagrunert))
- Since golang 1.17 both net.ParseIP and net.ParseCIDR rejects leading zeros in the dot-decimal notation of IPv4 addresses,
  Kubernetes will keep allowing leading zeros on IPv4 address to not break the compatibility.
