As expected, NetworkManager 1.30 is a major release that adds many great new features and improvements, including support for WPA3 Enterprise Suite-B 192 bit mode, support for handling Veth devices, a new “ipv4.dhcp-client-id=ipv6-duid” option for RFC4361, as well as new ethtool offload features.
This release also introduces new hostname settings for controlling and configuring the hostname from reverse DNS lookup and DHCP, support for configuring external-ids in Open vSwitch, and a longer timeout of the NetworkManager-wait-online.service of 60 seconds.
