 - [BREAKING CHANGE] Android: Minimum API level is now level 19 (Android 4.4)
+- [BREAKING CHANGE] Android, iOS: Exceptions occurring in Runnable tasks scheduled through Gdx.app.postRunnable() are no longer swallowed and will crash the app (add a protection if required).
 - iOS: The iOS backend now implements AudioDevice. It can be configured through IOSApplicationConfiguration with audioDeviceBufferSize/audioDeviceBufferCount
 - Fixed GlyphLayout for fixed width glyph offsets at the start and end of lines.
 - Fixed scene2d.ui layout for fractional positions and sizes.
