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.
As the kernel module always depends on the Linux kernel it is compiled against, it does not make sense to provide binaries on our website. As usual, you will find the signed tarballs in our download section:

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.

Oct 27th, 2020. Today the B.A.T.M.A.N. team publishes the October 2020 update to batman-adv and batctl! 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.

Jul 6th, 2020. Today the B.A.T.M.A.N. team publishes the July 2020 update to batman-adv, batctl and alfred! This release drops the support for the end-of-life Linux kernel versions (<4.3). The B.A.T.M.A.N. V throughput detection for ethernet devices without auto-negotiation was enabled again to support more configurations out of the box. Most users will still require a manual setting via the throughput_override for such devices. The automatic removal of (empty) batadv mesh interfaces during a batctl meshif bat0 interface del ....
was dropped. An explicit batctl meshif bat0 interface destroy
is now required to remove the batadv interface. Also several bugfixes and code cleanups are included in this version.

Mar 04th, 2020. Today the B.A.T.M.A.N. team publishes the March 2020 update to batman-adv, batctl and alfred! This release disables the (deprecated) sysfs support by default. The next milestone in this process is the removal of debugfs and sysfs support next year. The B.A.T.M.A.N. V code can now use the PHY transmission rates as another (fallback) source to calculate the expected throughput to specific neighbors. The alfred gps daemon gained support for the gpsd API 9 (libgps >= 3.20). Also several bugfixes and code cleanups are included in this version.
