  GeolocateControl breaking changes #4479

  • The option watchPosition has been replaced with trackUserLocation

  • The camera operation has changed from jumpTo (not animated) to fitBounds (animated). An effect of this is the map pitch is no longer reset, although the bearing is still reset to 0.

  • The accuracy of the geolocation provided by the device is used to set the view (previously it was fixed at zoom level 17). The maxZoom can be controlled via the new fitBoundsOptions option (defaults to 15).

Features and improvements

• Improve performance of updating GeoJSON sources #4069, @ezheidtmann

• Improve rendering speed of extrusion layers #4818

• Improve line label legibility in pitched views #4781

• Improve line label legibility on curved lines #4853

• Add user location tracking capability to GeolocateControl #4479, @andrewharvey

  • New option showUserLocation to draw a "dot" as a Marker on the map at the user's location
