   ports of native GL renderers from later accidentally attempting to activate
   "dormant" features if web browser implementations gain new WebGL extensions in
   the future, which `*glGetProcAddress()` is not able to support. (#20802)
+- Added Hi DPI support to GLFW. When enabled, GLFW automatically accounts for the
+  `devicePixelRatio` browser property and changes the size of the canvas accordingly
+  (including dynamically if the canvas is moved from a 4k screen to a 2k screen and 
+  vice-versa). `glfwGetFramebufferSize` now properly returns the canvas size in pixels, 
+  while `glfwGetWindowSize` returns the canvas size is screen size. By default,
+  this feature is disabled. You can enable it before creating a window by calling 
+  `glfwWindowHint(GLFW_SCALE_TO_MONITOR, GLFW_TRUE)`. You can also 
+  dynamically change it after the window has been created by calling
+  `glfwSetWindowAttrib(window, GLFW_SCALE_TO_MONITOR, GLFW_TRUE)`. (#20584)
