+- **Breaking:** The platform specific extensions for Windows `winit::platform::windows` have changed.

+- The internal bindings to the [Windows API](https://docs.microsoft.com/en-us/windows/) 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.
