Open-Mesh

April 8th, 2026: The B.A.T.M.A.N. team is excited to announce the release of the April 2026 update for batman-adv! Several bug fixes and code cleanups are included in this version.

Since the kernel module is always dependent on the specific Linux kernel it’s compiled against, providing precompiled binaries on our website is not feasible. As always, you can find the signed tarballs in the download section:
