- Added `GLFW_NO_API` for creating window without contexts
- Added `GLFW_CONTEXT_NO_ERROR` context hint for `GL_KHR_no_error` support
- Added `GLFW_INCLUDE_VULKAN` for including the Vulkan header
- Added `GLFW_CONTEXT_CREATION_API`, `GLFW_NATIVE_CONTEXT_API` and
`GLFW_EGL_CONTEXT_API` for run-time context creation API selection
- Added `GLFW_TRUE` and `GLFW_FALSE` as client API independent boolean values
- Added icons to examples on Windows and OS X
- Relaxed rules for native access header macros
- Removed dependency on external OpenGL or OpenGL ES headers
- Removed `_GLFW_USE_OPENGL`, `_GLFW_USE_GLESV1` and `_GLFW_USE_GLESV2`
configuration macros
- Removed `_GLFW_USE_OPENGL`, `_GLFW_USE_GLESV1`, `_GLFW_USE_GLESV2`,
`_GLFW_WGL`, `_GLFW_NSGL`, `_GLFW_GLX` and `_GLFW_EGL` configuration macros
- [Win32] Added support for Windows 8.1 per-monitor DPI
- [Win32] Replaced winmm with XInput and DirectInput for joystick input
- [Win32] Bugfix: Window creation would segfault if video mode setting required

The context creation API is used to enumerate pixel formats / framebuffer

- `_GLFW_NSGL` to use the Cocoa OpenGL framework
- `_GLFW_WGL` to use the Win32 WGL API

must also define `_GLFW_BUILD_DLL`. Otherwise, you must not define it.
