We are happy to announce Unity 2017.2.0p1. The release notes and the corresponding issue tracker link for issues fixed in this release are as shown below.

As always, patch releases are recommended only for users affected by those bugs fixed in that patch.

Improvements

2D - Exposed methods to set and retrieve Physics Shape from a Sprite.

2D - Sprites created by importing a texture now have a default Physics Shape generated.

Graphics - Added APIs to retrieve areas safe for UI rendering. Currently supported on iOS and tvOS only.

iOS - Added identification enums for iPhone 8, 8+ and X.

Shaders - Concatenated matrix macros (e.g. UNITY_MATRIX_MVP) are now changed to static variables to avoid repeated calculations.

tvOS - Implemented support for 4K AppleTV icons and splashscreens.

XR - Improved performance on Windows Mixed Reality by removing a potential thread stall that would occur whenever beginning a new frame while the previous frame had not completed presenting.
