DRAFT: Batman-adv 2025.1 released

April 15th, 2025: The B.A.T.M.A.N. team is excited to announce the release of the April 2025 update for batman-adv! This update introduces support for jumbo frames on top of batman-adv. This release also includes various bug fixes and code cleanups.

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:

Thanks

Many thanks to everyone who contributed patches:

And a special thanks to those who supported us with valuable advice and thorough testing:
