### Networking

|
|
|
|
|
|
|
|
|
- Allow the nftables firewall mode to be used with a daemon that is linked against libnftables when the `nft` command is not installed on the system. [moby/moby#52820](https://github.com/moby/moby/pull/52820)

|
|
|
|
- Don't publish container ports on host ports listed in `net.ipv4.ip_local_reserved_ports` when dynamically allocating ports. [moby/moby#52818](https://github.com/moby/moby/pull/52818)
