Hi Dave, the compat_* files are kept to help style authors adapt their styles to changes introduced with r2906 back in 2012. Please check http://www.mkgmap.org.uk/news/2013/12/22/more-flexibility-in-style-files-sty... <http://www.mkgmap.org.uk/news/2013/12/22/more-flexibility-in-style-files-style> The default style was adapted and does not need these files.

Juli 2016 01:43:24 An: Development list for mkgmap Betreff: [mkgmap-dev] compat_lines I'm working on trying to add the maxspeed tag value to my highways by creating or modifying style directives. In my investigations I noticed that the file compat_lines is not being called by any of my style files. Also, the default styles don't seem to use or call it either. Why is it present then? Or am I just missing a call that includes it somewhere else? Thanks, Dave -- Dave Swarthout Homer, Alaska Chiang Mai, Thailand Travel Blog at http://dswarthout.blogspot.com
