 Version         | Changes        |
 ----------------|----------------|
+**1.11.1** | Added HMM_PREFIX macro to a few functions that were missing it. |
 **1.11.0** | Added ability to customize or remove the default `HMM_` prefix on function names by defining a macro called `HMM_PREFIX(name)`. |
 **1.10.1** | Removed stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
 **1.10.0** | Made HMM_Perspective use vertical FOV instead of horizontal FOV for consistency with other graphics APIs. |

- *  @brief Functions related to accessing native handles.
- *
- *  **By using the native access functions you assert that you know what you're
- *  doing and how to fix problems caused by using them.  If you don't, you
- *  shouldn't be using them.**
- *
- *  Before the inclusion of @ref glfw3native.h, you may define zero or more

- *
- *  The chosen backends must match those the library was compiled for.  Failure
- *  to do this will cause a link-time error.
- *
- *  The available window API macros are:
- *  * `GLFW_EXPOSE_NATIVE_WIN32`
- *  * `GLFW_EXPOSE_NATIVE_COCOA`
- *  * `GLFW_EXPOSE_NATIVE_X11`
- *  * `GLFW_EXPOSE_NATIVE_WAYLAND`

- *  * `GLFW_EXPOSE_NATIVE_NSGL`
- *  * `GLFW_EXPOSE_NATIVE_GLX`
- *  * `GLFW_EXPOSE_NATIVE_EGL`
- *  * `GLFW_EXPOSE_NATIVE_OSMESA`
- *
- *  These macros select which of the native access functions that are declared
- *  and which platform-specific headers to include.  It is then up your (by
- *  definition platform-specific) code to handle which of these should be
- *  defined.
