winit/src/changelog/unreleased.md

The format is based on Keep a Changelog.

The sections should follow the order Added, Changed, Deprecated, Removed, and Fixed.

Platform specific changed should be added to the end of the section and grouped by platform name. Common API additions should have , implemented at the end for platforms where the API was initially implemented. See the following example on how to add them:

### Added

- Add `Window::turbo()`, implemented on X11, Wayland, and Web.
- On X11, add `Window::some_rare_api`.
- On X11, add `Window::even_more_rare_api`.
- On Wayland, add `Window::common_api`.
- On Windows, add `Window::some_rare_api`.

When the change requires non-trivial amount of work for users to comply with it, the migration guide should be added below the entry, like:

- Deprecate `Window` creation outside of `EventLoop::run`

  This was done to simply migration in the future. Consider the
  following code:

  // Code snippet.

  To migrate it we should do X, Y, and then Z, for example:

  // Code snippet.

The migration guide could reference other migration examples in the current changelog entry.

Unreleased

Added

• Add ActiveEventLoop::create_proxy().

Changed

• On Web, let events wake up event loop immediately when using ControlFlow::Poll.

• Bump MSRV from 1.70 to 1.73.

• Changed ApplicationHandler::user_event to user_wake_up, removing the generic user event.

  Winit will now only indicate that wake up happened, you will have to pair this with an external mechanism like std::sync::mpsc::channel if you want to send specific data to be processed on the main thread.

• Changed EventLoopProxy::send_event to EventLoopProxy::wake_up, it now only wakes up the loop.

• ApplicationHandler::create|destroy_surfaces() was split off from ApplicationHandler::resumed/suspended().

  ApplicationHandler::can_create_surfaces() should, for portability reasons to Android, be the only place to create render surfaces.

  ApplicationHandler::resumed/suspended() are now only emitted by iOS and Web and now signify actually resuming/suspending the application.

• Rename platform::web::*ExtWebSys to *ExtWeb.

• Change signature of EventLoop::run_app, EventLoopExtPumpEvents::pump_app_events and EventLoopExtRunOnDemand::run_app_on_demand to accept a impl ApplicationHandler directly, instead of requiring a &mut reference to it.

• DeviceId::dummy() and WindowId::dummy() are no longer marked unsafe.

Removed

• Remove EventLoop::run.

• Remove EventLoopExtRunOnDemand::run_on_demand.

• Remove EventLoopExtPumpEvents::pump_events.

• Remove Event.

• On iOS, remove platform::ios::EventLoopExtIOS and related platform::ios::Idiom type.

  This feature was incomplete, and the equivalent functionality can be trivially achieved outside of winit using objc2-ui-kit and calling UIDevice::currentDevice().userInterfaceIdiom().

Fixed

• On Wayland, avoid crashing when compositor is misbehaving.
• Account for different browser engine implementations of pointer movement coordinate space.
