The default setting for map_hyphen in the parametric router has been changed from True to False in the trunk, and will show up in the next stable release. This is to make the default setting the same as having no router at all.
If you're using URL hyphen mapping now, just add map_hyphen=True to the BASE router dict, and you won't see any change when you update. If you don't know what I'm talking about, you can probably ignore this message safely.
