- Fixed incorrect Screen-space Reflections rendering on OpenGL platforms (case 1368370)

## [3.2.0] - 2021-11-15

### Fixed
- Catch thrown errors in `PostProcessEffectRenderer`, preventing resources allocation leaks and crash (case 1221972)
- Fixed error thrown when changing post process layer right after creation or before destruction.
- Fix FXAA when render-target has no alpha channel (case 1344618) (case 1351502)

## [3.1.1] - 2021-03-08

### Fixed
- Fix for broken MSVO on desktop platforms.
- Fix for compilation issue with BuildTarget error on XboxOne platform.

## [3.1.0] - 2021-03-02
