[mkgmap-dev] Feedback on mkgmap r3111

From Gerd Petermann gpetermann_muenchen at hotmail.com on Wed Mar 19 09:24:28 GMT 2014

Hi Thorsten,

thanks for the nice feedback. I am now working on the 
code for "Turn restrictions with role=via ways ".

I am not sure how complex the changes are, so maybe we 
should call 3116 the new stable version.
