DRAFT: Batman-adv 2024.4 released¶

Dec 10th, 2024. Today the B.A.T.M.A.N. team publishes the December 2024 update to batman-adv! 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:
