 * SDL_GetTicks() now returns a 64-bit value and the tick values should be directly compared instead of using the SDL_TICKS_PASSED macro
 * Added SDL_GetTicksNS() to return the number of nanoseconds since the SDL library initialized
 * Added SDL_DelayNS() to specify a delay in nanoseconds, to the highest precision the system will support
-* The timestamp member of the SDL_Event structure is now in nanoseconds, filled in with SDL_GetTicksNS()

 The `timestamp` member of the SDL_Event structure now represents nanoseconds, and is populated with `SDL_GetTicksNS()`
 
+You should set the `event.common.timestamp` field before passing an event to `SDL_PushEvent()`. If the timestamp is 0 it will be filled in with `SDL_GetTicksNS()`.
