May 6th, 2022. Today the B.A.T.M.A.N. team publishes the April 2022 update to batman-adv! alfred got a new IPC message to request the current configuration of server instance. Also several bug fixes and code cleanups are included in this version.

Feb 3rd, 2022. Today the B.A.T.M.A.N. team publishes the February 2022 update to batman-adv! To improve the usability in containers, batman-adv can now be controlled and monitored via netlink in unprivileged containers. alfred got more flexible in the way it is handling interfaces. The batman-adv interface can now be changed at runtime and it can be started without any interfaces. Also several code cleanups are included in this version.

Aug 20th, 2021. Today the B.A.T.M.A.N. team publishes the August 2021 update to batman-adv, batctl and alfred! The multicast support in batman-adv can now utilize the Multicast Router Discovery of the Linux bridge to detect IPv4/IPv6 multicast listeners and routers. The broadcast packet handling was also redesigned to reduce the latency and to prepare the necessary infrastructure for interfaces specific handling. Also several bugfixes and code cleanups are included in this version.

Due to recent developments around the Freenode.org IRC network, the opinions about the usage of this service shifted dramatically.
A small poll in the IRC channel at the end of last week showed that most (actively participating) users wanted to leave freenode and the network with the most positive votes was hackint.org. The new home at ircs://irc.hackint.org/batadv was prepared on Sunday. You can find also other interesting channels in the neighborhood. #freifunk (including many communities), #gluon, #dn42, various CCC channels and many more.
We hope to see you soon in the new channel at ircs://irc.hackint.org/batadv
May 18th, 2021. Today the B.A.T.M.A.N. team publishes the May 2021 update to batman-adv, batctl and alfred! batctl gained the support for "*_json" commands which make it possible to query the batman-adv kernel module over generic netlink and receive the answer as JSON. The alfred server was modified to start the server even when batman-adv or interface(s) are not yet available. A special parameter "--force" must be provided to enable this behavior. Also several bugfixes and code cleanups are included in this version.

With the release of systemd v248, systemd-networkd now supports creation and management of B.A.T.M.A.N. Advanced interfaces.
The minimum required version of batman-adv to work with systemd-networkd is 2021.0.
An example .netdev file looks like the following:
[NetDev]
Name=bat0
Kind=batadv
[BatmanAdvanced]
GatewayMode=server
RoutingAlgorithm=batman-v
OriginatorIntervalSec=5

Jan 28th, 2021. Today the B.A.T.M.A.N. team publishes the January 2021 update to batman-adv, batctl and alfred! The deprecated support for batman-adv's sysfs and debugfs files was removed from all components. batctl and batman-adv now also allow the selection of the routing algorithm during the interface creation. This can be used to avoid the undefined behavior when multiple processes trying to create interfaces with different routing algorithms. Also several bugfixes and code cleanups are included in this version.

The bridge loop avoidance and translation table code received several fixes for bugs in connection with the multicast optimization. Which would otherwise potentially cause packet loss or even routing loops. Also several code cleanups are included in this version.
