* You can now use `--ipvs-exclude-cidrs` to specify a list of CIDR's which the IPVS proxier should not touch when cleaning up IPVS rules. ([#62083](https://github.com/kubernetes/kubernetes/pull/62083), [@rramkumar1](https://github.com/rramkumar1))

  when the kernel version was 4.15 or higher. With the kernel 4.15 the sysctl became namespaced.
