While Microsoft has been updating native Windows 10 apps on PC with Project Neon elements, Mobile apps were left behind. That changes with latest Maps app update. Windows 10 UWP Maps app has been updated on both Mobile and PC with visual design refresh. It is the first native app on Mobile that has Neon elements.
This Maps update has come to Fast Ring for now and apart from visual design change it also brings ability to sort and filter search results for hotels and restaurants. You can also get directions for trips with multiple stops a feature than went first to Mobile, it seems.
Finally, it seems Microsoft will convey what has changed in latest update every time an update has been rolled-out to Maps.
