NetworkManager 1.52 is out today as the newest version of this widely-used system network service and network configuration tool suite for Linux systems.
NetworkManager 1.52 adds IPVLAN interface support, now allows manually configuring the authentication of LTE’s initial EPS Bearer, support for the IPv6-only preferred DHCPv4 option, support automatically adding routes to DNS servers via new properties, supporting OCI in nm-cloud-setup, and adding support for the ethtool FEC mode.
=============================================
NetworkManager-1.52
Overview of changes since NetworkManager-1.50
=============================================* Store interactive history in `$XDG_CACHE_HOME/nmcli-history` instead of `~/.nmcli-history`
* Add new ipv4.link-local=fallback to set an IPv4 link-local address when no other IPv4 is set.
* Remove support for building with Autotools
* Add IPVLAN interface support
* Allow to manually configure the authentication of LTE’s initial EPS Bearer.
* Add support for the “IPv6-only preferred” DHCPv4 option (RFC 8925), used to indicate that a host supports an IPv6-only mode and is willing to forgo obtaining an IPv4 address if the network provides IPv6 connectivity.
* Support automatically adding routes to DNS servers via the ipv4.routed-dns and ipv6.routed-dns properties; when enabled, each name server is reached only via the device that specifies it.
* Support OCI in nm-cloud-setup
* Added support for ethtool FEC mode
* Add new ipv4.shared-dhcp-range and ipv4.shared-dhcp-lease-time, which allows you to customize the DHCP range and lease time offered by DHCP server in `shared` connection method.
* DNS servers can now be specified with a URI-like syntax which supports DNS over TLS name servers.
* The initrd-generator understands the “rd.net.dns” option to configure global name servers.
* Drop support for the “dhcpcanon” DHCP client.
* global-dns configuration section now has 2 additional keys: “resolve-mode” and “certification-authority”.
* Dnsconfd plugin can now be used for configuration of system-wide DNS caching resolver. If dnsconfd plugin is enabled and ipvX.routed-dns is set to -1 then adding routes is by default enabled.
* Add “shared” method to the IPv6 configuration options in nmtui.
NetworkManager 1.52 can be downloaded from the FreeDesktop.org GitLab.
An early feature already merged for what will become NetworkManager 1.54 is adding systemd services to provide networking in the initrd.
