new stable release of the interface to simplify the configuration of network parameters - . to support VPN, OpenConnect, PPTP, OpenVPN, and OpenSWAN are developed through their own development cycles.
NetworkManager 1.20:
- Added support for wireless mesh networks, each node in which is connected through neighboring nodes;
- Removed obsolete components. This includes the removal of the libnm-glib library, which was replaced by the libnm library in NetworkManager 1.0, the removal of the ibft plugin (to pass network configuration data from the firmware, use nm-initrd-generator from the initrd), and the "main.monitor- connection-files" in NetworkManager.conf (should explicitly call "nmcli connection load" or "nmcli connection reload");
- By default, the built-in DHCP client ("internal" mode) is enabled instead of the previously used dhclient application. You can change the default value using the "--with-config-dhcp-default" build option or through the main.dhcp setting in the configuration file;
- Added the ability to configure the fq_codel (Fair Queuing Controlled Delay) queue management discipline for pending packets and the mirred action for traffic mirroring;
- For distributions, the ability to place dispatch scripts in the /usr/lib/NetworkManager directory is provided, which can be used in system images that are available in read-only mode and clear /etc at each start;
- Added support for read-only directories to the keyfile plugin
("/usr/lib/NetworkManager/system-connections"), whose profiles can be modified or deleted via D-Bus (in this case, unmodifiable files in /usr/lib/ are overridden by files saved in /etc or / run); - libnm has redesigned JSON settings parsing code and provides more stringent parameter checking;
- Added support for the "suppress_prefixlength" attribute in policy routing rules;
- For VPN WireGuard, support for scripts for automatically assigning the default route "wireguard.ip4-auto-default-route" and "wireguard.ip6-auto-default-route" is implemented;
- The implementation of settings management plugins and the method of storing profiles on disk has been redesigned. Added support for migrating connection profiles between plugins;
- In-memory profiles are now handled only by the keyfile plugin and stored in the /run directory, which avoids losing profiles after NetworkManager restart and makes it possible to use the FS-based API to create in-memory profiles;
- Added new D-Bus method , which allows you to block auto-connection of a profile at the time of its creation. The method added flag "no-reapply", in which changing the contents of the connection profile does not automatically change the actual configuration of the device until the profile is reactivated;
- Added "ipv6.method=disabled" setting to disable IPv6 for a device.
