A bit more than 3 months and 257 commits since NetworkManager 1.46, a new release is ready: NetworkManager 1.48.
Let’s take a look at the most interesting parts!
Deprecate building with autotools
Building with autotools is now deprecated and will be completely removed in the next development cycle. We recommend using meson to build NetworkManager, for basic setup, see the CONTRIBUTING.md file.
Deprecate mac-address-blacklist property
NetworkManager is embracing conscious language, as part of this work, we have
deprecated 802-11-wireless and 802-11-wired property
mac-address-blacklist in favor of mac-address-denylist. We encourage you to
migrate to the new property as soon as possible.
Support changing the OpenSSL ciphers for 802.1X authentication
OpenSSL sometimes moves ciphers among SECLEVELs. Some servers are too old to
support newer ciphers so an expert should be allowed to define the ciphers for
the connection. Therefore, now it is possible to change the OpenSSL ciphers for
802.1X authentication via connection property 802-1x.openssl-ciphers.
What else?
Allow IPv6 SLAAC and static IPv6 DNS server assignment for modem broadband when IPv6 device address was not explicitly passed on by ModemManager.
Support sending DHCP RELEASE message when bringing down the connection.
Support setting IPv6 preferred and valid lifetime of autogenerated temporary addresses.
Fix a performance issue that was leading to a 100% CPU usage by NetworkManager if external programs were doing a big amount of routes updates.
Fix detection of 6 GHz band capability for WiFi devices.
