April 17th, 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:

February 7th, 2025: The B.A.T.M.A.N. team is excited to announce the release of the February 2025 update for batman-adv! This update introduces support for subsecond ping intervals in batctl. To optimize OGM size, VLAN 0 is now treated as an "untagged VLAN," and announced TT changes now include fewer redundant modifications. Additionally, the OGM translation table changes parser in batman-adv has received a critical fix for a regression introduced in version 2024.4. This release also includes various bug fixes and code cleanups.

Feb 1st, 2024. Today the B.A.T.M.A.N. team publishes the February 2024 update to batman-adv! batman-adv gained support for the new stateless, TVLV capable batman-adv multicast packet type. The originator of a multicast packet includes all destinations for this packet. The routers on the way will potentially split this destination list (based on the best next hops) and and forward for each chunk an adjusted packet to the best next neighbor. Also several bug fixes and code cleanups are included in this version.
