 # 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`.

+    - Change `WindowEvent::KeyboardInput` to contain a `KeyEvent`.
+    - Change `Event::Key` to contain a `RawKeyEvent`.
+  - Remove `Event::ReceivedCharacter`. In its place, you should use

+  - Replace `VirtualKeyCode` with the `Key` enum.
+  - Replace `ScanCode` with the `KeyCode` enum.
+  - Rename `ModifiersState::LOGO` to `SUPER` and `ModifiersState::CTRL` to `CONTROL`.
+  - Add `PhysicalKey` wrapping `KeyCode` and `NativeKeyCode`.
+  - Add `KeyCode` to refer to keys (roughly) by their physical location.
+  - Add `NativeKeyCode` to represent raw `KeyCode`s which Winit doesn't
+    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.
 - Removed platform-specific extensions that should be retrieved through `raw-window-handle` trait implementations instead:
   - `platform::windows::HINSTANCE`.
   - `WindowExtWindows::hinstance`.

+//!   pre-defined settings. All "retina displays" have a scaling factor above 1.0 by default,
+//!   but the specific value varies across devices.
 //! - **X11:** Many man-hours have been spent trying to figure out how to handle DPI in X11. Winit
 //!   currently uses a three-pronged approach:
-//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable, if present.
+//!   + Use the value in the `WINIT_X11_SCALE_FACTOR` environment variable if present.
 //!   + If not present, use the value set in `Xft.dpi` in Xresources.
 //!   + Otherwise, calculate the scale factor based on the millimeter monitor dimensions provided by XRandR.
 //!
 //!   If `WINIT_X11_SCALE_FACTOR` is set to `randr`, it'll ignore the `Xft.dpi` field and use the
 //!   XRandR scaling method. Generally speaking, you should try to configure the standard system
 //!   variables to do what you want before resorting to `WINIT_X11_SCALE_FACTOR`.
-//! - **Wayland:** Scale factor is suggested by the the compositor.
+//! - **Wayland:** The scale factor is suggested by the compositor for each window individually. The

 //! - **iOS:** Scale factors are set by Apple to the value that best suits the device, and range
 //!   from `1.0` to `3.0`. See [this article][apple_1] and [this article][apple_2] for more
