Summary:
As of iOS 8 the MKMapView maximum zoom level has been reduced from 21 to 20. This has significant impacts for indoor mapping solutions built on top of MKMapView.

Steps to Reproduce:
1. Unzip MKMapViewSample.zip
2. Run MKMapViewSample on Xcode 5 targeting an iOS 7 iPhone (simulator or device).
3. Notice the overlay sample encompasses the the entire view .
4. Now, open MKMapViewSample in Xcode 6.
5. Run MKMapViewSample with Xcode 6 targeting an iOS 8 iPhone (simulator or device).
6. Notice that the maximum zoom level is much less than iOS 7.

Expected Results:
Maximum zoom level to be the same or better in iOS 8.

Actual Results:
Maximum zoom level on iOS 8 is much worse than iOS 7.

Version:
iOS 8.0 (12A365) and 7.1.2 (11D257)

Notes:
We were hoping that the maximum zoom level would improve in iOS 8 to better enable indoor mapping applications built on top of MKMapView. The current zoom level makes indoor mapping solutions built on top of MKMapView untenable except for very large venues.

Configuration:
iPhone 5S AT&T using WiFi, iPhone 5 AT&T using WiFi
