[mkgmap-dev] Change in Garmin IMG format?

Tue Jul 13 23:36:55 BST 2021

The issue exists for me on my Edge 1030 even in classic mode, and with 
the popularity layer turned off.  I checked it twice to be sure.  I am 
going to revert to the previous firmware version so I can get my custom 
symbology back.
