 - **Breaking:** Bump `ndk` version to 0.6, ndk-sys to `v0.3`, `ndk-glue` to `0.6`.
 - Remove no longer needed `WINIT_LINK_COLORSYNC` environment variable.
 - **Breaking:** Rename the `Exit` variant of `ControlFlow` to `ExitWithCode`, which holds a value to control the exit code after running. Add an `Exit` constant which aliases to `ExitWithCode(0)` instead to avoid major breakage. This shouldn't affect most existing programs.
+- **Breaking:** The platform specific extensions for Windows `winit::platform::windows` have changed. The remaining `HANDLE`-like types `HWND` and `HMENU` were converted from winapi types to `*mut c_void`. This was done to be consistent with the other types, which were already `*mut c_void` and to not expose types of internal dependencies.
+- The internal bindings to the [Windows API](https://docs.microsoft.com/en-us/windows/win32/) were changed from the unofficial [winapi](https://github.com/retep998/winapi-rs) bindings to the official Microsoft [windows-sys](https://github.com/microsoft/windows-rs) bindings.
