-# 0.29.2
-
-- **Breaking:** Bump MSRV from `1.60` to `1.65`.
-- **Breaking:** Add `Event::MemoryWarning`; implemented on iOS/Android.
-- **Breaking:** Bump `ndk` version to `0.8.0`, ndk-sys to `0.5.0`, `android-activity` to `0.5.0`.
-- **Breaking:** Change default `ControlFlow` from `Poll` to `Wait`.
+- 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`.
-- **Breaking:** Moved `ControlFlow::Exit` to `EventLoopWindowTarget::exit()` and `EventLoopWindowTarget::exiting()` and removed `ControlFlow::ExitWithCode(_)` entirely.
+- 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:** `EventLoop::new` and `EventLoopBuilder::build` now return `Result<Self, EventLoopError>`
-- **Breaking:** `WINIT_UNIX_BACKEND` was removed in favor of standard `WAYLAND_DISPLAY` and `DISPLAY` variables.
-- **Breaking:** on Wayland, dispatching user created Wayland queue won't wake up the loop unless winit has event to send back.
+- **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:** `ScaleFactorChanged` now contains a writer instead of a reference to update inner size.
-- **Breaking** `run() -> !` has been replaced by `run() -> Result<(), EventLoopError>` for returning errors without calling `std::process::exit()` ([#2767](https://github.com/rust-windowing/winit/pull/2767))
-- **Breaking** Removed `EventLoopExtRunReturn` / `run_return` in favor of `EventLoopExtPumpEvents` / `pump_events` and `EventLoopExtRunOnDemand` / `run_on_demand` ([#2767](https://github.com/rust-windowing/winit/pull/2767))
-- `RedrawRequested` is no longer guaranteed to be emitted after `MainEventsCleared`, it is now platform-specific when the event is emitted after being requested via `redraw_request()`.
-  - On Windows, `RedrawRequested` is now driven by `WM_PAINT` messages which are requested via `redraw_request()`
-- **Breaking** `LoopDestroyed` renamed to `LoopExiting` ([#2900](https://github.com/rust-windowing/winit/issues/2900))
-- **Breaking** `RedrawEventsCleared` removed ([#2900](https://github.com/rust-windowing/winit/issues/2900))

-- **Breaking:** On Web, `instant` is now replaced by `web_time`.
-- **Breaking:** On Web, dropped support for Safari versions below 13.1.
-- **Breaking:** On Web, the canvas output bitmap size is no longer adjusted.
-- **Breaking:** On Web, the canvas size is not controlled by Winit anymore and external changes to the canvas size will be reported through `WindowEvent::Resized`.
-- **Breaking:** Updated `bitflags` crate version to `2`, which changes the API on exposed types.
-- **Breaking:** `CursorIcon::Arrow` was removed.
-- **Breaking:** `CursorIcon::Hand` is now named `CursorIcon::Pointer`.
-- **Breaking:** `CursorIcon` is now used from the `cursor-icon` crate.
-- **Breaking:** `WindowExtWebSys::canvas()` now returns an `Option`.
-- **Breaking:** Overhaul keyboard input handling.

-    - Change `WindowEvent::KeyboardInput` to contain a `KeyEvent`.

-    understand.
-  - Add `Key` to represent the keys after they've been interpreted by the
-    active (software) keyboard layout.
-  - Add `NamedKey` to represent the categorized keys.
-  - Add `NativeKey` to represent raw `Key`s which Winit doesn't understand.
-  - Add `KeyLocation` to tell apart `Key`s which usually "mean" the same thing,
-    but can appear simultaneously in different spots on the same keyboard
-    layout.
-  - Add `Window::reset_dead_keys` to enable application-controlled cancellation
-    of dead key sequences.
-  - Add `KeyEventExtModifierSupplement` to expose additional (and less
-    portable) interpretations of a given key-press.
-  - Add `PhysicalKeyExtScancode`, which lets you convert between scancodes and
-    `PhysicalKey`.
-  - `ModifiersChanged` now uses dedicated `Modifiers` struct.
+- On Android, fix `DeviceId` to contain device id's.
+- Add `Window::set_blur` to request a blur behind the window; implemented on Wayland for now.
+- On Web, fix `ControlFlow::WaitUntil` to never wake up **before** the given time.
+- Add `Window::show_window_menu` to request a titlebar/system menu; implemented on Wayland/Windows for now.

+- **Breaking:** `EventLoop::new` and `EventLoopBuilder::build` now return `Result<Self, EventLoopError>`
+- On X11, set `visual_id` in returned `raw-window-handle`.
+- **Breaking:** on Wayland, dispatching user created wayland queue won't wake up the loop unless winit has event to send back.
 - Removed platform-specific extensions that should be retrieved through `raw-window-handle` trait implementations instead:

 - On macOS, fix crash when dropping `Window`.
+- On Web, use `Window.requestIdleCallback()` for `ControlFlow::Poll` when available.
