@ -66,6 +66,7 @@ used by the tests and examples and are not required to build the library.
- Added `glfwSetWindowSizeLimits` and `glfwSetWindowAspectRatio` for setting
absolute and relative window size limits
- Added `GLFW_NO_API` for creating window without contexts
- Added `GLFW_TRUE` and `GLFW_FALSE` as client API independent boolean values
- Removed dependency on external OpenGL or OpenGL ES headers
- [Cocoa] Removed support for OS X 10.6
