Version mkgmap-r3241 was committed by gerd on Wed, 30 Apr 2014 apply reverse-oneway-v3.patch This patch makes sure that multiple copies of an OSM way with different oneway=* tags are not treated the same. Without this patch the result is more or less unpredictable if you use something like this: xyz=* { add oneway=-1 } [0x1010 resolution 23 continue] xyz=* { set oneway=yes } [0x1011 resolution 23 continue] xyz=* { set oneway=-1 } [0x10 road_speed=1 resolution 23] todo: check code for restriction relations
