Open-Mesh

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.

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:
