- Kube-proxy will no longer hold service node ports open on the node. Users are still advised not to run any listener on node ports range used by kube-proxy. ([#108496](https://github.com/kubernetes/kubernetes/pull/108496), [@khenidak](https://github.com/khenidak))

  address ranges (“CIDR blocks”).
  
  In particular, octets within IPv4 addresses are not allowed to have any leading
  `0`s, and IPv4-mapped IPv6 values (e.g. `::ffff:192.168.0.1`) are forbidden.
  These sorts of values can potentially cause security problems when different
  components interpret the same string as referring to different IP addresses
  (as in CVE-2021-29923).
  

- The maximum number of ports allowed in EndpointSlices has been increased from 100 to 20,000 ([#99795](https://github.com/kubernetes/kubernetes/pull/99795), [@robscott](https://github.com/robscott)) [SIG Network]
