A few remarks about the projection issue: our ultimate goal is to fix the projection for all regions (just like 6.13.7). We are not quite there yet, so we use band-aids trying to fix the projection for the majority of our users.
For small map products we now (as of 22.214.171.124) use the center of the map as a reference point. So there will be no distortion at the center. The further North or South from the center you go the worse the distortion will get. This works fairly well for most of our products.
For larger products this is not ideal. For Canada especially this did not work so we put in a special fix that should make Canada-only maps less distorted where it matters (in the South).
We still allow users to change the projection angle in the registry. We decided not to openly provide a user interface for this, but made it a bit easier to change the angle without having to meddle directly in the registry. You now can hit Ctrl-Alt-A in MapSource to set the projection angle for the current map product
. You will need to restart MapSource for this to have any effect.
Changes to the projection angle that you made in 126.96.36.199 will not be used
(the registry location for the angle has changed). You will have to set the angle again. This was done so that the projection angle adjustment can be shared amongst Garmin applications (BaseCamp 3.0.x & MapSource 6.16.x will now both use the angle you set)
