Talking about the app features, here are some of the bigger / easier to notice differences:

- added automatic backups for bookmarks and tracks

- added 100m-step altitude isolines to all regions that had worse or no isolines

- a big rework of the map colors - lighter, warmer, friendlier

- add a setting to customize the leftmost button or hide it

- removed semi-transparent background in Subway layer
