|

|

- Added native monitor handle access to native API
|

- Added `glfwSetDropCallback` and `GLFWdropfun` for receiving dropped files
|

- Added `empty` test program for verifying posting of empty events

- Bugfix: The debug context attribute was set from `GL_ARB_debug_output` even

when a debug context had not been requested
|

- Bugfix: The particles example was not linked against the threading library
