Jul 6th, 2020. Today the B.A.T.M.A.N. team publishes the July 2020 update to batman-adv, batctl and alfred! This release drops the support for the end-of-life Linux kernel versions (<4.3). The B.A.T.M.A.N. V throughput detection for ethernet devices without auto-negotiation was enabled again to support more configurations out of the box. Most users will still require a manual setting via the throughput_override for such devices. The automatic removal of (empty) batadv mesh interfaces during a batctl meshif bat0 interface del .... was dropped. An explicit batctl meshif bat0 interface destroy is now required to remove the batadv interface. Also several bugfixes and code cleanups are included in this version.

Mar 04th, 2020. Today the B.A.T.M.A.N. team publishes the March 2020 update to batman-adv, batctl and alfred! This release disables the (deprecated) sysfs support by default. The next milestone in this process is the removal of debugfs and sysfs support next year. The B.A.T.M.A.N. V code can now use the PHY transmission rates as another (fallback) source to calculate the expected throughput to specific neighbors. The alfred gps daemon gained support for the gpsd API 9 (libgps >= 3.20). Also several bugfixes and code cleanups are included in this version.

Aug 1th, 2019. Today the B.A.T.M.A.N. team publishes the August 2019 update to batman-adv, batctl and alfred! The multicast optimization got support for group-aware optimizations for multicast addresses of scope greater than link-local. batctl was adjusted to handle such information and packets in various subcommands. Also support for hardif (aka. slave/lower interface) specific settings was implemented. This required a change in how meshif and vlans are specified for subcommands. Instead of using "-m" for both meshif and vlans (and now hardifs), they were splitted into special subcommand prefixes:
meshif <netdev>vlan <vdev>meshif <netdev> vid <vid>hardif <netdev>
To start a ping on bat2, following command should be used:
$ batctl meshif bat2 ping 02:ba:de:af:fe:01
As usual, this release also contains various bugfixes and code cleanups.

May 23th, 2019. Today the B.A.T.M.A.N. team publishes the May 2019 update to batman-adv, batctl and alfred! To improve the overhead in networks with multicast listeners, adjustments for the multicast optimization were implemented which enable multicast-to-unicast conversion. batman-adv can now update the DAT entry timeouts on incoming ARP replies to reduce the broadcast overhead even further. The sysfs integration in batman-adv is now optional and can be turned off during the compilation. A system without the sysfs support also requires additional changes in batctl which are shipped now as part of this release. Also the deprecated debugfs log support in batctl was dropped together with the support of MAC-to-originator translation via debugfs. As usual, this release also contains various bugfixes and code cleanups.

Mar 28th, 2019. Today the B.A.T.M.A.N. team publishes the March 2019 update to batman-adv, batctl and alfred! The distributed hash table now parses DHCP packets to speed up the learning process of new IPv4 addresses. This should reduce the number of required ARP packets when a client just received a new IP address and then wants to start to transfer data via this router. Also batman-adv and batctl were modified to exchange configuration settings via generic netlink instead of sysfs. As usual, this release also contains various bugfixes and code cleanups.
