- Removed `_GLFW_USE_OPENGL`, `_GLFW_USE_GLESV1` and `_GLFW_USE_GLESV2`
|
||||
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 system to be restarted
|
||||
- [Win32] Bugfix: MinGW import library lacked the `lib` prefix
