 3.1.49 (in development)
 -----------------------
+- The `glfwSetWindowSize` function no longer switches to fullscreen when the
+  width/height provided as parameters match the screen size. This behavior
+  now matches the behavior of SDL and glut. In order to switch to fullscreen,
+  the client code should invoke `Module.requestFullscreen(...)` from a user 
+  triggered event otherwise the browser raises an error. (#20600)
