- (none) - iOS: Fixed crash while building iOS project on El Capitan.
- (728134) - iOS: Fixed Game Center authentication crash on iOS 9.0.
- (718387), (720698) - iOS: Fixed system dynamic font support on iOS 9 where only the first font could be read from certain font collections and font substitutes, as identified by the OS, were not handled.
