Light version update: 
Because of the reduction of zoomlevels the file size has shrinked with 25%.
Cycleways with surface=(crushed_)shell(s) added to the 'unpaved' category.  Cycleways are now distinguished in 3 categories:

1. surface=paved,asphalt, concrete, paving_stones or unset
   
   garmin type 0x16
2. surface=compacted,gravel,shells,cobblestones
   
   garmin type 0x0e, avoid unpaved = no
   
3. surface=unpaved,sand,dirt,clay,ash,bad,earth,grass,rock; smoothness=bad or worse
   
   garmin type 0x0b, avoid unpaved = yes
   

Changes in the typ file:
highway=construction is moved from 0x0b to 0x10019 and are not routable anymore.
Type 0x0b is now used for unpaved cycleways (cat. 3), these are avoided if unpaved is checked in the routing.
