DRAFT: Batman-adv 2019.1 released

Mar 19th, 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.

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:
