# Unreleased
- Changes below are considered **breaking**.
- Change all occurrences of `EventsLoop` to `EventLoop`.
- Previously flat API is now exposed through `event`, `event_loop`, `monitor`, and `window` modules.
- `os` module changes:
- Renamed to `platform`.
- All traits now have platform-specific suffixes.
- Exposes new `desktop` module on Windows, Mac, and Linux.
- Changes to event loop types:
- `EventLoopProxy::wakeup` has been removed in favor of `send_event`.
- **Major:** New `run` method drives winit event loop.
- Returns `!` to ensure API behaves identically across all supported platforms.
- This allows `emscripten` implementation to work without lying about the API.
- `ControlFlow`'s variants have been replaced with `Wait`, `WaitUntil(Instant)`, `Poll`, and `Exit`.
- Is read after `EventsCleared` is processed.
- `Wait` waits until new events are available.
- `WaitUntil` waits until either new events are available or the provided time has been reached.
- `Poll` instantly resumes the event loop.
- `Exit` aborts the event loop.
- Takes a closure that implements `'static + FnMut(Event<T>, &EventLoop<T>, &mut ControlFlow)`.
- `&EventLoop<T>` is provided to allow new `Window`s to be created.
- **Major:** `platform::desktop` module exposes `EventLoopExtDesktop` trait with `run_return` method.
- Behaves identically to `run`, but returns control flow to the calling context can take non-`'static` closures.
- `EventLoop`'s `poll_events` and `run_forever` methods have been removed in favor of `run` and `run_return`.
- Changes to events:
- Remove `Event::Awakened` in favor of `Event::UserEvent(T)`.
- Can be sent with `EventLoopProxy::send_event`.
- Rename `WindowEvent::Refresh` to `WindowEvent::RedrawRequested`.
- `RedrawRequested` can be sent by the user with the `Window::request_redraw` method.
- `EventLoop`, `EventLoopProxy`, and `Event` are now generic over `T`, for use in `UserEvent`.
- **Major:** Add `NewEvents(StartCause)`, `EventsCleared`, and `LoopDestroyed` variants to `Event`.
- `NewEvents` is emitted when new events are ready to be processed by event loop.
- `StartCause` describes why new events are available, with `ResumeTimeReached`, `Poll`, `WaitCancelled`, and `Init` (sent once at start of loop).
- `EventsCleared` is emitted when all available events have been processed.
- Can be used to perform logic that depends on all events being processed (e.g. an iteration of a game loop).
- `LoopDestroyed` is emitted when the `run` or `run_return` method is about to exit.
- Rename `MonitorId` to `MonitorHandle`.
