 # Unreleased
 
-- Renamed `EventLoopExtRunOnDemand` / `run_ondemand` to `EventLoopExtRunOnDemand` / `run_on_demand`.
-- Make iOS `MonitorHandle` and `VideoMode` usable from other threads.
-- On Web, `ControlFlow::WaitUntil` now uses the Prioritized Task Scheduling API. `setTimeout()`, with a trick to circumvent throttling to 4ms, is used as a fallback.
-- On Web, never return a `MonitorHandle`.
-- **Breaking:** Move `Event::RedrawRequested` to `WindowEvent::RedrawRequested`.
-- On macOS, fix crash in `window.set_minimized(false)`.
-- On Web, enable event propagation and let `DeviceEvent`s appear after `WindowEvent`s.
-- On Web, take all transient activations on the canvas and window into account to queue a fullscreen request.
-- On Web, remove any fullscreen requests from the queue when an external fullscreen activation was detected.
-- On Wayland, fix `TouchPhase::Canceled` being sent for moved events.
-- Mark `startup_notify` unsafe functions as safe.
-- Fix a bug where Wayland would be chosen on Linux even if the user specified `with_x11`. (#3058)
-- **Breaking:** Moved `ControlFlow` to `EventLoopWindowTarget::set_control_flow()` and `EventLoopWindowTarget::control_flow()`.
-- **Breaking:** Moved `ControlFlow::Exit` to `EventLoopWindowTarget::exit()` and `EventLoopWindowTarget::exiting()` and removed `ControlFlow::ExitWithCode(_)` entirely.
-- On Web, add `EventLoopWindowTargetExtWebSys` and `PollStrategy`, which allows to set different strategies for `ControlFlow::Poll`. By default the Prioritized Task Scheduling API is used, but an option to use `Window.requestIdleCallback` is available as well. Both use `setTimeout()`, with a trick to circumvent throttling to 4ms, as a fallback.
-- Implement `PartialOrd` and `Ord` for `MouseButton`.
-- On X11, fix event loop not waking up on `ControlFlow::Poll` and `ControlFlow::WaitUntil`.
+- **Breaking:** Use `RequestIgnored` as the error type in `InnerSizeWriter::request_inner_size`.

+  - Add `CustomCursorExtWebSys::from_url` to allow loading cursor images from URLs.
+  - Add `CustomCursorExtWebSys::from_animation` to allow creating animated cursors from other `CustomCursor`s.
+- On macOS, add services menu.
+- **Breaking:** On Web, remove queuing fullscreen request in absence of transient activation.
+- On Web, fix setting cursor icon overriding cursor visibility.
+- **Breaking:** On Web, return `RawWindowHandle::WebCanvas` instead of `RawWindowHandle::Web`.

+- **Breaking:** Rename `VideoMode` to `VideoModeHandle` to represent that it doesn't hold static data.
+- **Breaking:** No longer export `platform::x11::XNotSupported`.
+- **Breaking:** Renamed `platform::x11::XWindowType` to `platform::x11::WindowType`.
+- Add the `OwnedDisplayHandle` type for allowing safe display handle usage outside of trivial cases.
+- **Breaking:** Rename `TouchpadMagnify` to `PinchGesture`, `SmartMagnify` to `DoubleTapGesture` and `TouchpadRotate` to `RotationGesture` to represent the action rather than the intent.
+- on iOS, add detection support for `PinchGesture`, `DoubleTapGesture` and `RotationGesture`.
+- on Windows: add `with_system_backdrop`, `with_border_color`, `with_title_background_color`, `with_title_text_color` and `with_corner_preference`

+- Added `EventLoop::builder`, which is intended to replace the (now deprecated) `EventLoopBuilder::new`.
+- **Breaking:** Changed the signature of `EventLoop::with_user_event` to return a builder.
+- **Breaking:** Removed `EventLoopBuilder::with_user_event`, the functionality is now available in `EventLoop::with_user_event`.
+- Add `Window::builder`, which is intended to replace the (now deprecated) `WindowBuilder::new`.
+- On X11, reload dpi on `_XSETTINGS_SETTINGS` update.
+- On X11, fix deadlock when adjusting DPI and resizing at the same time.
+- On Wayland, fix `Focused(false)` being send when other seats still have window focused.
+- On Wayland, fix `Window::set_{min,max}_inner_size` not always applied.

 Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
