The packet structure should be identified by this version. The stuff which appears in a packet jumps a little bit with each version because we change stuff in trunk/master and in next and import those changes to the packet structure out-of-order. + +Following changes were identified and documented. The changes are to the last COMPAT_VERSION and not to the last change in a branch. So "added xyz on master, removed xyz on next and re-added xyz on master" does only mean that xyz was always there in master, but the version in next dropped that change and thus generated a new COMPAT_VERSION. + +|| Version || Branch || Changes || +|| 1 || trunk || Initial definitions of batman_packet, icmp_packet, unicast_packet, bcast_packet, ethernet type 0x0842 || +|| 5 || trunk || information in batman_packet was reordered, tq, old_orig and hnas were added || +|| 6 || trunk, v0.1 || vis_packet type added, version fields added to each packet, ethernet type changed to 0x4305 || +|| 7 || trunk || unused gw flags removed, reordered icmp and batman packet || +|| 8 || trunk, v0.2, v0.2.1, v2010.0.0 || source field introduced in vis packets || +|| 9 || trunk || Gateway flags added to batman_packet, primaries_first_hop flag added for bonding, special icmp messages for route record added || +|| 10 || trunk || 32 bit sequence numbers added/changed, ttl were added to broadcasts || +|| 11 || next, v2010.1.0* || gateway flags were removed || +|| 12 || trunk || unicast fragmentation added, gateway flags were readded || +|| 13 || next, v2010.2.0* || gateway flags were removed || + +(* means future version with already defined feature set) + +There is a special COMPAT_VERSION 200 which is only used by saxnet.
