DRAFT: Batman-adv 2025.5 released¶

December 16nd, 2025: The B.A.T.M.A.N. team is excited to announce the release of the December 2025 update for batman-adv! This release includes various code cleanups and drops support for EOL kernels.

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:
