+The changelog can also be viewed [on docs.rs][docs_rs] or [on the current
+master docs][master_docs].
 
-Please keep one empty line before and after all headers. (This is required for `git` to produce a conflict when a release is made while a PR is open and the PR's changelog entry would go into the wrong section).
-
-And please only add new entries to the top of this list, right below the `# Unreleased` header.

-# Unreleased
-
-# 0.28.6
-
-- On macOS, fixed memory leak when getting monitor handle.
-- On macOS, fix `Backspace` being emitted when clearing preedit with it.
-
-# 0.28.5
-
-- On macOS, fix `key_up` beind ignored when `Ime` is disabled.
-
-# 0.28.4
-
-- On macOS, fix empty marked text blocking regular input.
-- On macOS, fixed potential panic when getting refresh rate.
-- On macOS, fix crash when calling `Window::set_ime_position` from another thread.
-- On macOS, fixed memory leak when getting monitor handle.
-
-# 0.28.3
-
-- Fix macOS memory leaks.
-
-# 0.28.2
-
-- Implement `HasRawDisplayHandle` for `EventLoop`.
-- On macOS, set resize increments only for live resizes.
-- On Wayland, fix rare crash on DPI change
-- Web: Added support for `Window::theme`.
-- On Wayland, fix rounding issues when doing resize.
-- On macOS, fix wrong focused state on startup.
-- On Windows, fix crash on setting taskbar when using Visual Studio debugger.
-- On macOS, resize simple fullscreen windows on windowDidChangeScreen events.
-
-# 0.28.1
-
-- On Wayland, fix crash when dropping a window in multi-window setup.
-
-# 0.28.0
-
-- On macOS, fixed `Ime::Commit` persisting for all input after interacting with `Ime`.
-- On macOS, added `WindowExtMacOS::option_as_alt` and `WindowExtMacOS::set_option_as_alt`.
-- On Windows, fix window size for maximized, undecorated windows.
-- On Windows and macOS, add `WindowBuilder::with_active`.
-- Add `Window::is_minimized`.
-- On X11, fix errors handled during `register_xlib_error_hook` invocation bleeding into winit.
-- Add `Window::has_focus`.
-- On Windows, fix `Window::set_minimized(false)` not working for windows minimized by `Win + D` hotkey.
-- **Breaking:** On Web, touch input no longer fires `WindowEvent::Cursor*`, `WindowEvent::MouseInput`, or `DeviceEvent::MouseMotion` like other platforms, but instead it fires `WindowEvent::Touch`.
-- **Breaking:** Removed platform specific `WindowBuilder::with_parent` API in favor of `WindowBuilder::with_parent_window`.
-- On Windows, retain `WS_MAXIMIZE` window style when un-minimizing a maximized window.
-- On Windows, fix left mouse button release event not being sent after `Window::drag_window`.
-- On macOS, run most actions on the main thread, which is strictly more correct, but might make multithreaded applications block slightly more.
-- On macOS, fix panic when getting current monitor without any monitor attached.
-- On Windows and MacOS, add API to enable/disable window buttons (close, minimize, ...etc).
-- On Windows, macOS, X11 and Wayland, add `Window::set_theme`.
-- **Breaking:** Remove `WindowExtWayland::wayland_set_csd_theme` and `WindowBuilderExtX11::with_gtk_theme_variant`.
-- On Windows, revert window background to an empty brush to avoid white flashes when changing scaling.
-- **Breaking:** Removed `Window::set_always_on_top` and related APIs in favor of `Window::set_window_level`.
-- On Windows, MacOS and X11, add always on bottom APIs.
-- On Windows, fix the value in `MouseButton::Other`.
-- On macOS, add `WindowExtMacOS::is_document_edited` and `WindowExtMacOS::set_document_edited` APIs.
-- **Breaking:** Removed `WindowBuilderExtIOS::with_root_view_class`; instead, you should use `[[view layer] addSublayer: ...]` to add an instance of the desired layer class (e.g. `CAEAGLLayer` or `CAMetalLayer`). See `vulkano-win` or `wgpu` for examples of this.
-- On MacOS and Windows, add `Window::set_content_protected`.
-- On MacOS, add `EventLoopBuilderExtMacOS::with_activate_ignoring_other_apps`.
-- On Windows, fix icons specified on `WindowBuilder` not taking effect for windows created after the first one.
-- On Windows and macOS, add `Window::title` to query the current window title.
-- On Windows, fix focusing menubar when pressing `Alt`.
-- On MacOS, made `accepts_first_mouse` configurable.
-- Migrated `WindowBuilderExtUnix::with_resize_increments` to `WindowBuilder`.
-- Added `Window::resize_increments`/`Window::set_resize_increments` to update resize increments at runtime for X11/macOS.
-- macOS/iOS: Use `objc2` instead of `objc` internally.
-- **Breaking:** Bump MSRV from `1.57` to `1.60`.
-- **Breaking:** Split the `platform::unix` module into `platform::x11` and `platform::wayland`. The extension types are similarly renamed.
-- **Breaking:**: Removed deprecated method `platform::unix::WindowExtUnix::is_ready`.
-- Removed `parking_lot` dependency.
-- **Breaking:** On macOS, add support for two-finger touchpad magnification and rotation gestures with new events `WindowEvent::TouchpadMagnify` and `WindowEvent::TouchpadRotate`. Also add support for touchpad smart-magnification gesture with a new event `WindowEvent::SmartMagnify`.

-
-# 0.20.0 Alpha 1 (2019-06-21)
-
-- 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 and 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`.
-- Removed `serde` implementations from `ControlFlow`.
-- Rename several functions to improve both internal consistency and compliance with Rust API guidelines.

-- On Windows, fix icon not showing up in corner of window.
-- On X11, change DPI scaling factor behavior. First, winit tries to read it from "Xft.dpi" XResource, and uses DPI calculation from xrandr dimensions as fallback behavior.
-
-# Version 0.19.0 (2019-03-06)
-
-- On X11, we will use the faster `XRRGetScreenResourcesCurrent` function instead of `XRRGetScreenResources` when available.

-- On Windows, cursor grabs used to get perpetually canceled when the grabbing window lost focus. Now, cursor grabs automatically get re-initialized when the window regains focus and the mouse moves over the client area.
-- On Windows, only vertical mouse wheel events were handled. Now, horizontal mouse wheel events are also handled.
-- On Windows, ignore the AltGr key when populating the `ModifersState` type.

-# Version 0.18.1 (2018-12-30)
-
-- On macOS, fix `Yen` (JIS) so applications receive the event.

-- Introduce `WindowBuilderExt::with_app_id` to allow setting the application ID on Wayland.
-- On Windows, catch panics in event loop child thread and forward them to the parent thread. This prevents an invocation of undefined behavior due to unwinding into foreign code.
-- On Windows, fix issue where resizing or moving window combined with grabbing the cursor would freeze program.
-- On Windows, fix issue where resizing or moving window would eat `Awakened` events.
-- On Windows, exiting fullscreen after entering fullscreen with disabled decorations no longer shrinks window.

-- Added further clarifications to the DPI docs.
-- On Linux, if neither X11 nor Wayland manage to initialize, the corresponding panic now consists of a single line only.
-- Add optional `serde` feature with implementations of `Serialize`/`Deserialize` for DPI types and various event types.
-- Add `PartialEq`, `Eq`, and `Hash` implementations on public types that could have them but were missing them.
-- On X11, drag-and-drop receiving an unsupported drop type can no longer cause the WM to freeze.

-
-# Version 0.17.2 (2018-08-19)
-
-- On macOS, fix `<C-Tab>` so applications receive the event.
-- On macOS, fix `<Cmd-{key}>` so applications receive the event.
-- On Wayland, key press events will now be repeated.
-
-# Version 0.17.1 (2018-08-05)
-
-- On X11, prevent a compilation failure in release mode for versions of Rust greater than or equal to 1.30.
-- Fixed deadlock that broke fullscreen mode on Windows.
-
-# Version 0.17.0 (2018-08-02)
-
-- Cocoa and core-graphics updates.
-- Fixed thread-safety issues in several `Window` functions on Windows.
-- On MacOS, the key state for modifiers key events is now properly set.
-- On iOS, the view is now set correctly. This makes it possible to render things (instead of being stuck on a black screen), and touch events work again.
-- Added NetBSD support.
-- **Breaking:** On iOS, `UIView` is now the default root view. `WindowBuilderExt::with_root_view_class` can be used to set the root view objective-c class to `GLKView` (OpenGLES) or `MTKView` (Metal/MoltenVK).
-- On iOS, the `UIApplication` is not started until `Window::new` is called.
-- Fixed thread unsafety with cursor hiding on macOS.
-- On iOS, fixed the size of the `JmpBuf` type used for `setjmp`/`longjmp` calls. Previously this was a buffer overflow on most architectures.
-- On Windows, use cached window DPI instead of repeatedly querying the system. This fixes sporadic crashes on Windows 7.
-
-# Version 0.16.2 (2018-07-07)
-
-- On Windows, non-resizable windows now have the maximization button disabled. This is consistent with behavior on macOS and popular X11 WMs.
-- Corrected incorrect `unreachable!` usage when guessing the DPI factor with no detected monitors.
-
-# Version 0.16.1 (2018-07-02)
-
-- Added logging through `log`. Logging will become more extensive over time.
-- On X11 and Windows, the window's DPI factor is guessed before creating the window. This _greatly_ cuts back on unsightly auto-resizing that would occur immediately after window creation.
-- Fixed X11 backend compilation for environments where `c_char` is unsigned.
-
-# Version 0.16.0 (2018-06-25)
-
-- Windows additionally has `WindowBuilderExt::with_no_redirection_bitmap`.
-- **Breaking:** Removed `VirtualKeyCode::LMenu` and `VirtualKeyCode::RMenu`; Windows now generates `VirtualKeyCode::LAlt` and `VirtualKeyCode::RAlt` instead.
-- On X11, exiting fullscreen no longer leaves the window in the monitor's top left corner.
-- **Breaking:** `Window::hidpi_factor` has been renamed to `Window::get_hidpi_factor` for better consistency. `WindowEvent::HiDPIFactorChanged` has been renamed to `WindowEvent::HiDpiFactorChanged`. DPI factors are always represented as `f64` instead of `f32` now.
-- The Windows backend is now DPI aware. `WindowEvent::HiDpiFactorChanged` is implemented, and `MonitorId::get_hidpi_factor` and `Window::hidpi_factor` return accurate values.
-- Implemented `WindowEvent::HiDpiFactorChanged` on X11.
-- On macOS, `Window::set_cursor_position` is now relative to the client area.
-- On macOS, setting the maximum and minimum dimensions now applies to the client area dimensions rather than to the window dimensions.
-- On iOS, `MonitorId::get_dimensions` has been implemented and both `MonitorId::get_hidpi_factor` and `Window::get_hidpi_factor` return accurate values.
-- On Emscripten, `MonitorId::get_hidpi_factor` now returns the same value as `Window::get_hidpi_factor` (it previously would always return 1.0).
-- **Breaking:** The entire API for sizes, positions, etc. has changed. In the majority of cases, winit produces and consumes positions and sizes as `LogicalPosition` and `LogicalSize`, respectively. The notable exception is `MonitorId` methods, which deal in `PhysicalPosition` and `PhysicalSize`. See the documentation for specifics and explanations of the types. Additionally, winit automatically conserves logical size when the DPI factor changes.
-- **Breaking:** All deprecated methods have been removed. For `Window::platform_display` and `Window::platform_window`, switch to the appropriate platform-specific `WindowExt` methods. For `Window::get_inner_size_points` and `Window::get_inner_size_pixels`, use the `LogicalSize` returned by `Window::get_inner_size` and convert as needed.
-- HiDPI support for Wayland.
-- `EventsLoop::get_available_monitors` and `EventsLoop::get_primary_monitor` now have identical counterparts on `Window`, so this information can be acquired without an `EventsLoop` borrow.
-- `AvailableMonitorsIter` now implements `Debug`.
-- Fixed quirk on macOS where certain keys would generate characters at twice the normal rate when held down.
-- On X11, all event loops now share the same `XConnection`.
-- **Breaking:** `Window::set_cursor_state` and `CursorState` enum removed in favor of the more composable `Window::grab_cursor` and `Window::hide_cursor`. As a result, grabbing the cursor no longer automatically hides it; you must call both methods to retain the old behavior on Windows and macOS. `Cursor::NoneCursor` has been removed, as it's no longer useful.
-- **Breaking:** `Window::set_cursor_position` now returns `Result<(), String>`, thus allowing for `Box<Error>` conversion via `?`.
-
-# Version 0.15.1 (2018-06-13)
-
-- On X11, the `Moved` event is no longer sent when the window is resized without changing position.
-- `MouseCursor` and `CursorState` now implement `Default`.
-- `WindowBuilder::with_resizable` implemented for Windows, X11, Wayland, and macOS.
-- `Window::set_resizable` implemented for Windows, X11, Wayland, and macOS.
-- On X11, if the monitor's width or height in millimeters is reported as 0, the DPI is now 1.0 instead of +inf.
-- On X11, the environment variable `WINIT_HIDPI_FACTOR` has been added for overriding DPI factor.
-- On X11, enabling transparency no longer causes the window contents to flicker when resizing.
-- On X11, `with_override_redirect` now actually enables override redirect.
-- macOS now generates `VirtualKeyCode::LAlt` and `VirtualKeyCode::RAlt` instead of `None` for both.
-- On macOS, `VirtualKeyCode::RWin` and `VirtualKeyCode::LWin` are no longer switched.
-- On macOS, windows without decorations can once again be resized.
-- Fixed race conditions when creating an `EventsLoop` on X11, most commonly manifesting as "[xcb] Unknown sequence number while processing queue".
-- On macOS, `CursorMoved` and `MouseInput` events are only generated if they occurs within the window's client area.
-- On macOS, resizing the window no longer generates a spurious `MouseInput` event.
-
-# Version 0.15.0 (2018-05-22)
-
-- `Icon::to_cardinals` is no longer public, since it was never supposed to be.
-- Wayland: improve diagnostics if initialization fails
-- Fix some system event key doesn't work when focused, do not block keyevent forward to system on macOS
-- On X11, the scroll wheel position is now correctly reset on i3 and other WMs that have the same quirk.
-- On X11, `Window::get_current_monitor` now reliably returns the correct monitor.
-- On X11, `Window::hidpi_factor` returns values from XRandR rather than the inaccurate values previously queried from the core protocol.
-- On X11, the primary monitor is detected correctly even when using versions of XRandR less than 1.5.
-- `MonitorId` now implements `Debug`.
-- Fixed bug on macOS where using `with_decorations(false)` would cause `set_decorations(true)` to produce a transparent titlebar with no title.
-- Implemented `MonitorId::get_position` on macOS.
-- On macOS, `Window::get_current_monitor` now returns accurate values.
-- Added `WindowBuilderExt::with_resize_increments` to macOS.
-- **Breaking:** On X11, `WindowBuilderExt::with_resize_increments` and `WindowBuilderExt::with_base_size` now take `u32` values rather than `i32`.
-- macOS keyboard handling has been overhauled, allowing for the use of dead keys, IME, etc. Right modifier keys are also no longer reported as being left.
-- Added the `Window::set_ime_spot(x: i32, y: i32)` method, which is implemented on X11 and macOS.
-- **Breaking**: `os::unix::WindowExt::send_xim_spot(x: i16, y: i16)` no longer exists. Switch to the new `Window::set_ime_spot(x: i32, y: i32)`, which has equivalent functionality.
-- Fixed detection of `Pause` and `Scroll` keys on Windows.
-- On Windows, alt-tabbing while the cursor is grabbed no longer makes it impossible to re-grab the cursor.
-- On Windows, using `CursorState::Hide` when the cursor is grabbed now ungrabs the cursor first.
-- Implemented `MouseCursor::NoneCursor` on Windows.
-- Added `WindowBuilder::with_always_on_top` and `Window::set_always_on_top`. Implemented on Windows, macOS, and X11.
-- On X11, `WindowBuilderExt` now has `with_class`, `with_override_redirect`, and `with_x11_window_type` to allow for more control over window creation. `WindowExt` additionally has `set_urgent`.
-- More hints are set by default on X11, including `_NET_WM_PID` and `WM_CLIENT_MACHINE`. Note that prior to this, the `WM_CLASS` hint was automatically set to whatever value was passed to `with_title`. It's now set to the executable name to better conform to expectations and the specification; if this is undesirable, you must explicitly use `WindowBuilderExt::with_class`.
-
-# Version 0.14.0 (2018-05-09)
-
-- Created the `Copy`, `Paste` and `Cut` `VirtualKeyCode`s and added support for them on X11 and Wayland
-- Fix `.with_decorations(false)` in macOS
-- On Mac, `NSWindow` and supporting objects might be alive long after they were `closed` which resulted in apps consuming more heap then needed. Mainly it was affecting multi window applications. Not expecting any user visible change of behaviour after the fix.
-- Fix regression of Window platform extensions for macOS where `NSFullSizeContentViewWindowMask` was not being correctly applied to `.fullsize_content_view`.
-- Corrected `get_position` on Windows to be relative to the screen rather than to the taskbar.
-- Corrected `Moved` event on Windows to use position values equivalent to those returned by `get_position`. It previously supplied client area positions instead of window positions, and would additionally interpret negative values as being very large (around `u16::MAX`).
-- Implemented `Moved` event on macOS.
-- On X11, the `Moved` event correctly use window positions rather than client area positions. Additionally, a stray `Moved` that unconditionally accompanied `Resized` with the client area position relative to the parent has been eliminated; `Moved` is still received alongside `Resized`, but now only once and always correctly.
-- On Windows, implemented all variants of `DeviceEvent` other than `Text`. Mouse `DeviceEvent`s are now received even if the window isn't in the foreground.
-- `DeviceId` on Windows is no longer a unit struct, and now contains a `u32`. For `WindowEvent`s, this will always be 0, but on `DeviceEvent`s it will be the handle to that device. `DeviceIdExt::get_persistent_identifier` can be used to acquire a unique identifier for that device that persists across replugs/reboots/etc.
-- Corrected `run_forever` on X11 to stop discarding `Awakened` events.
-- Various safety and correctness improvements to the X11 backend internals.
-- Fixed memory leak on X11 every time the mouse entered the window.
-- On X11, drag and drop now works reliably in release mode.
-- Added `WindowBuilderExt::with_resize_increments` and `WindowBuilderExt::with_base_size` to X11, allowing for more optional hints to be set.
-- Rework of the wayland backend, migrating it to use [Smithay's Client Toolkit](https://github.com/Smithay/client-toolkit).
-- Added `WindowBuilder::with_window_icon` and `Window::set_window_icon`, finally making it possible to set the window icon on Windows and X11. The `icon_loading` feature can be enabled to allow for icons to be easily loaded; see example program `window_icon.rs` for usage.
-- Windows additionally has `WindowBuilderExt::with_taskbar_icon` and `WindowExt::set_taskbar_icon`.
-- On Windows, fix panic when trying to call `set_fullscreen(None)` on a window that has not been fullscreened prior.
-
-# Version 0.13.1 (2018-04-26)
-
-- Ensure necessary `x11-dl` version is used.
-
-# Version 0.13.0 (2018-04-25)
-
-- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for MacOS.
-- Implement `WindowBuilder::with_maximized`, `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for Windows.
-- On Windows, `WindowBuilder::with_fullscreen` no longer changing monitor display resolution.
-- Overhauled X11 window geometry calculations. `get_position` and `set_position` are more universally accurate across different window managers, and `get_outer_size` actually works now.
-- Fixed SIGSEGV/SIGILL crashes on macOS caused by stabilization of the `!` (never) type.
-- Implement `WindowEvent::HiDPIFactorChanged` for macOS
-- On X11, input methods now work completely out of the box, no longer requiring application developers to manually call `setlocale`. Additionally, when input methods are started, stopped, or restarted on the server end, it's correctly handled.
-- Implemented `Refresh` event on Windows.
-- Properly calculate the minimum and maximum window size on Windows, including window decorations.
-- Map more `MouseCursor` variants to cursor icons on Windows.
-- Corrected `get_position` on macOS to return outer frame position, not content area position.
-- Corrected `set_position` on macOS to set outer frame position, not content area position.
-- Added `get_inner_position` method to `Window`, which gets the position of the window's client area. This is implemented on all applicable platforms (all desktop platforms other than Wayland, where this isn't possible).
-- **Breaking:** the `Closed` event has been replaced by `CloseRequested` and `Destroyed`. To migrate, you typically just need to replace all usages of `Closed` with `CloseRequested`; see example programs for more info. The exception is iOS, where `Closed` must be replaced by `Destroyed`.
-
-# Version 0.12.0 (2018-04-06)
-
-- Added subclass to macos windows so they can be made resizable even with no decorations.
-- Dead keys now work properly on X11, no longer resulting in a panic.
-- On X11, input method creation first tries to use the value from the user's `XMODIFIERS` environment variable, so application developers should no longer need to manually call `XSetLocaleModifiers`. If that fails, fallbacks are tried, which should prevent input method initialization from ever outright failing.
-- Fixed thread safety issues with input methods on X11.
-- Add support for `Touch` for win32 backend.
-- Fixed `Window::get_inner_size` and friends to return the size in pixels instead of points when using HIDPI displays on OSX.
-
-# Version 0.11.3 (2018-03-28)
-
-- Added `set_min_dimensions` and `set_max_dimensions` methods to `Window`, and implemented on Windows, X11, Wayland, and OSX.
-- On X11, dropping a `Window` actually closes it now, and clicking the window's × button (or otherwise having the WM signal to close it) will result in the window closing.
-- Added `WindowBuilderExt` methods for macos: `with_titlebar_transparent`,
-  `with_title_hidden`, `with_titlebar_buttons_hidden`,
-  `with_fullsize_content_view`.
-- Mapped X11 numpad keycodes (arrows, Home, End, PageUp, PageDown, Insert and Delete) to corresponding virtual keycodes
-
-# Version 0.11.2 (2018-03-06)
-
-- Impl `Hash`, `PartialEq`, and `Eq` for `events::ModifiersState`.
-- Implement `MonitorId::get_hidpi_factor` for MacOS.
-- Added method `os::macos::MonitorIdExt::get_nsscreen() -> *mut c_void` that gets a `NSScreen` object matching the monitor ID.
-- Send `Awakened` event on Android when event loop is woken up.
-
-# Version 0.11.1 (2018-02-19)
-
-- Fixed windows not receiving mouse events when click-dragging the mouse outside the client area of a window, on Windows platforms.
-- Added method `os::android::EventsLoopExt:set_suspend_callback(Option<Box<Fn(bool) -> ()>>)` that allows glutin to register a callback when a suspend event happens
-
-# Version 0.11.0 (2018-02-09)
-
-- Implement `MonitorId::get_dimensions` for Android.
-- Added method `os::macos::WindowBuilderExt::with_movable_by_window_background(bool)` that allows to move a window without a titlebar - `with_decorations(false)`
-- Implement `Window::set_fullscreen`, `Window::set_maximized` and `Window::set_decorations` for Wayland.
-- Added `Caret` as VirtualKeyCode and support OSX ^-Key with german input.
-
-# Version 0.10.1 (2018-02-05)
-
-_Yanked_
-
-# Version 0.10.0 (2017-12-27)
-
-- Add support for `Touch` for emscripten backend.
-- Added support for `DroppedFile`, `HoveredFile`, and `HoveredFileCancelled` to X11 backend.
-- **Breaking:** `unix::WindowExt` no longer returns pointers for things that aren't actually pointers; `get_xlib_window` now returns `Option<std::os::raw::c_ulong>` and `get_xlib_screen_id` returns `Option<std::os::raw::c_int>`. Additionally, methods that previously returned `libc::c_void` have been changed to return `std::os::raw::c_void`, which are not interchangeable types, so users wanting the former will need to explicitly cast.
-- Added `set_decorations` method to `Window` to allow decorations to be toggled after the window is built. Presently only implemented on X11.
-- Raised the minimum supported version of Rust to 1.20 on MacOS due to usage of associated constants in new versions of cocoa and core-graphics.
-- Added `modifiers` field to `MouseInput`, `MouseWheel`, and `CursorMoved` events to track the modifiers state (`ModifiersState`).
-- Fixed the emscripten backend to return the size of the canvas instead of the size of the window.
-
-# Version 0.9.0 (2017-12-01)
-
-- Added event `WindowEvent::HiDPIFactorChanged`.
-- Added method `MonitorId::get_hidpi_factor`.
-- Deprecated `get_inner_size_pixels` and `get_inner_size_points` methods of `Window` in favor of
-`get_inner_size`.
-- **Breaking:** `EventsLoop` is `!Send` and `!Sync` because of platform-dependant constraints,
-  but `Window`, `WindowId`, `DeviceId` and `MonitorId` guaranteed to be `Send`.
-- `MonitorId::get_position` now returns `(i32, i32)` instead of `(u32, u32)`.
-- Rewrite of the wayland backend to use wayland-client-0.11
-- Support for dead keys on wayland for keyboard utf8 input
-- Monitor enumeration on Windows is now implemented using `EnumDisplayMonitors` instead of
-`EnumDisplayDevices`. This changes the value returned by `MonitorId::get_name()`.
-- On Windows added `MonitorIdExt::hmonitor` method
-- Impl `Clone` for `EventsLoopProxy`
-- `EventsLoop::get_primary_monitor()` on X11 will fallback to any available monitor if no primary is found
-- Support for touch event on wayland
-- `WindowEvent`s `MouseMoved`, `MouseEntered`, and `MouseLeft` have been renamed to
-`CursorMoved`, `CursorEntered`, and `CursorLeft`.
-- New `DeviceEvent`s added, `MouseMotion` and `MouseWheel`.
-- Send `CursorMoved` event after `CursorEntered` and `Focused` events.
-- Add support for `ModifiersState`, `MouseMove`, `MouseInput`, `MouseMotion` for emscripten backend.
-
-# Version 0.8.3 (2017-10-11)
-
-- Fixed issue of calls to `set_inner_size` blocking on Windows.
-- Mapped `ISO_Left_Tab` to `VirtualKeyCode::Tab` to make the key work with modifiers
-- Fixed the X11 backed on 32bit targets
-
-# Version 0.8.2 (2017-09-28)
-
-- Uniformize keyboard scancode values accross Wayland and X11 (#297).
-- Internal rework of the wayland event loop
-- Added method `os::linux::WindowExt::is_ready`
-
-# Version 0.8.1 (2017-09-22)
-
-- Added various methods to `os::linux::EventsLoopExt`, plus some hidden items necessary to make
-  glutin work.
-
-# Version 0.8.0 (2017-09-21)
-
-- Added `Window::set_maximized`, `WindowAttributes::maximized` and `WindowBuilder::with_maximized`.
-- Added `Window::set_fullscreen`.
-- Changed `with_fullscreen` to take a `Option<MonitorId>` instead of a `MonitorId`.
-- Removed `MonitorId::get_native_identifer()` in favor of platform-specific traits in the `os`
-  module.
-- Changed `get_available_monitors()` and `get_primary_monitor()` to be methods of `EventsLoop`
-  instead of stand-alone methods.
-- Changed `EventsLoop` to be tied to a specific X11 or Wayland connection.
-- Added a `os::linux::EventsLoopExt` trait that makes it possible to configure the connection.
-- Fixed the emscripten code, which now compiles.
-- Changed the X11 fullscreen code to use `xrandr` instead of `xxf86vm`.
-- Fixed the Wayland backend to produce `Refresh` event after window creation.
-- Changed the `Suspended` event to be outside of `WindowEvent`.
-- Fixed the X11 backend sometimes reporting the wrong virtual key (#273).

-# Winit Contributing Guidelines
+# Contribution Guidelines
 
-## Scope
-[See `FEATURES.md`](./FEATURES.md). When requesting or implementing a new Winit feature, you should
-consider whether or not it's directly related to window creation or input handling. If it isn't, it
-may be worth creating a separate crate that extends Winit's API to add that functionality.
+This document contains guidelines for contributing code to winit. It has to be
+followed in order for your patch to be approved and applied.
 
+## Contributing
 
-## Reporting an issue
+Anyone can contribute to winit, however given that it's a cross platform
+windowing toolkit getting certain changes incorporated could be challenging.
 
-When reporting an issue, in order to help the maintainers understand what the problem is, please make
-your description of the issue as detailed as possible:
+To save your time it's wise to check already opened [pull requests][prs] and
+[issues][issues]. In general, bug fixes and missing implementations are always
+accepted, however larger new API proposals should go into the issue first. When
+in doubt contact us on [Matrix][matrix] or via opening an issue.
 
-- if it is a bug, please provide clear explanation of what happens, what should happen, and how to
-  reproduce the issue, ideally by providing a minimal program exhibiting the problem
-- if it is a feature request, please provide a clear argumentation about why you believe this feature
-  should be supported by winit
+### Windows
 
-## Making a pull request
+To run the examples on Windows, you must have symlinks enabled, see
+[this][git-windows-symlinks].
 
-When making a code contribution to winit, before opening your pull request, please make sure that:
+[git-windows-symlinks]: https://gitforwindows.org/symbolic-links.html
 
-- your patch builds with Winit's minimal supported rust version - Rust 1.60.
-- you tested your modifications on all the platforms impacted, or if not possible detail which platforms
-  were not tested, and what should be tested, so that a maintainer or another contributor can test them
-- you updated any relevant documentation in winit
-- you left comments in your code explaining any part that is not straightforward, so that the
-  maintainers and future contributors don't have to try to guess what your code is supposed to do
-- your PR adds an entry to the changelog file if the introduced change is relevant to winit users.
+### Submitting your work and handling review
 
-  You needn't worry about the added entry causing conflicts, the maintainer that merges the PR will
-  handle those for you when merging (see below).
-- if your PR affects the platform compatibility of one or more features or adds another feature, the
-  relevant sections in [`FEATURES.md`](https://github.com/rust-windowing/winit/blob/master/FEATURES.md#features)
-  should be updated.
+All patches have to be sent on Github as [pull requests][prs]. To simplify your
+life during review it's recommended to check the "give contributors write access
+to the branch" checkbox.
 
-Once your PR is open, you can ask for review by a maintainer of your platform. Winit's merging policy
-is that a PR must be approved by at least two maintainers of winit before being merged, including
-at least a maintainer of the platform (a maintainer making a PR themselves counts as approving it).
+We use unstable Rustfmt options across the project, so please run
+`cargo +nightly fmt` before submitting your work. If you are unable to do so,
+the maintainers can do it for you before merging, just state so in your pull
+request description. For details on how to use nightly, consult [the
+documentation][toolchains].
 
-Once your PR is deemed ready, the merging maintainer will take care of resolving conflicts in
-`CHANGELOG.md` (but you must resolve other conflicts yourself). Doing this requires that you check the
-"give contributors write access to the branch" checkbox when creating the PR.
+When editing markdown files (`.md`) they must be wrapped at 80 characters.
 
-## Maintainers & Testers
+[toolchains]: https://rust-lang.github.io/rustup/concepts/toolchains.html
 
-The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
+#### Handling review
 
-If you are interested in being pinged when testing is needed for a certain platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
+During the review process certain events could require an action from your side,
+common patterns and reactions are described below.
 
-## Release process
+_Event:_ The CI fails to build, but it looks like it is not your fault. Not
+communicating so could result in maintainers not looking into your patch,
+since they may assume that you're still working on it.\
+_Desired behaviour:_ Write a message saying roughly the following "The CI
+failure is unrelated", so that the maintainers will fix it for you.
 
-Given that winit is a widely used library we should be able to make a patch
+_Event:_ Maintainer requested changes to your PR.\
+_Desired behavior:_ Once you address the request, you should re-request a review
+with GitHub's UI. If you don't agree with what maintainer suggested, you
+should state your objections and re-request the review. That will indicate that
+the ball is on maintainer's side.
+
+_Event:_ You've opened a PR, but maintainer shortly after commented that they
+want to work on that themselves.\
+_Desired behavior:_ Discuss with the maintainer regarding their plans if they
+were not outlined in the initial response, because such response means that they
+are not interested in reviewing your code. Such thing could happen when
+underestimating complexity of the task you're solving or when your patch
+mandate certain downstream designs. In general, the maintainer will likely
+close your PR in order to prevent work being done on it.

+
+## Maintainers
+
+Winit has plenty of maintainers with different backgrounds, different time
+available to work on Winit, and reasons to be winit maintainer in the first
+place. To ensure that Winit's code quality does not decrease over time and to
+make it easier to teach new maintainers the "winit way of doing things" the
+common policies and routines are defined in this section.
+
+The current maintainers for each platform are listed in [this file][CODEOWNERS].
+
+### Contributions handling
+
+The maintainers must ensure that the external contributions meet Winit's
+quality standards. If it's not, it **is the maintainer's responsibility** to
+bring it on par, which includes:
+
+  - Ensure that formatting is consistent and `CHANGELOG` messages are clear
+    for the end users.
+  - Improve the commit message, so it'll be easier for other maintainers to
+    understand the motivation without going through all the discussions on the
+    particular patch/PR.
+  - Ensure that the proposed patch doesn't break platform parity. If the
+    breakage is desired by contributor, an issue should be opened to discuss
+    with other maintainers before merging.
+  - Always fix CI issues before merging if they don't originate from the
+    submitted work.
+
+However, maintainers should give some leeway for external contributors, so they
+don't feel discouraged contributing, for example:
+
+  - Suggest a patch to resolve style issues, if it's the only issue with the
+    submitted work. Keep in mind that pushing the resolution yourself is not
+    desired, because the contributor might not agree with what you did.
+  - Be more explicit on how things should be done if you don't like the
+    approach.
+  - Suggest to finish the PR for them if they're absent for a while and you need
+    the proposed changes to move forward with something. In such cases the
+    maintainer must preserve attribution with `Co-authored-by`, `Suggested-by`,
+    or keep the original committer.
+  - Rebase their work for them when massive changes to the Winit codebase were
+    introduced.
+
+When reviewing code of other maintainers all of the above is on the maintainer
+who submitted the patch. Interested maintainers could help push the work over
+the finish line, but teaching other maintainers should be preferred.
+
+For a _regular_ contributor to winit, the maintainer should slowly start
+requiring contributor to match *maintainer* quality standards when writing
+patches and commit messages.
+
+### Contributing
+
+When submitting a patch, the maintainer should follow the general contributing
+guidelines, however greater attention to detail is expected in this case.
+
+To make life simpler for other maintainers it's suggested to create your branch
+under the project repository instead of your own fork. The naming scheme is
+`github_user_name/branch_name`. Doing so will make your work easier to rebase
+for other maintainers when you're absent.
+
+### Administrative Actions
+
+Some things (such as changing required CI steps, adding contributors, ...)
+require administrative permissions. If you don't have those, ask about the
+change in an issue. If you have the permissions, discuss it with at least one
+other admin before making the change.
+
+### Release process
+
+Given that winit is a widely used library, we should be able to make a patch
 releases at any time we want without blocking the development of new features.
 
 To achieve these goals, a new branch is created for every new release. Releases
 and later patch releases are committed and tagged in this branch.
 
 The exact steps for an exemplary `0.2.0` release might look like this:
-  1. Initially the version on the latest master is `0.1.0`
+  1. Initially, the version on the latest master is `0.1.0`
   2. A new `v0.2.x` branch is created for the release
-  3. In the branch, the version is bumped to `v0.2.0`
-  4. The new commit in the branch is tagged `v0.2.0`
-  5. The version is pushed to crates.io
-  6. A GitHub release is created for the `v0.2.0` tag
-  7. On master, the version is bumped to `0.2.0` and the CHANGELOG is updated
-  
-When doing a patch release the process is similar:
-  1. Initially the version of the latest release is `0.2.0`
+  3. Update released `cfg_attr` in `src/changelog/mod.rs` to `v0.2.md`
+  4. Move entries from `src/changelog/unreleased.md` into
+     `src/changelog/v0.2.md`
+  5. In the branch, the version is bumped to `v0.2.0`
+  6. The new commit in the branch is tagged `v0.2.0`
+  7. The version is pushed to crates.io
+  8. A GitHub release is created for the `v0.2.0` tag
+  9. On master, the version is bumped to `0.2.0`, and the changelog is updated
+
+When doing a patch release, the process is similar:
+  1. Initially, the version of the latest release is `0.2.0`
   2. Checkout the `v0.2.x` branch
   3. Cherry-pick the required non-breaking changes into the `v0.2.x`
-  4. Follow steps 3-7 of the regular release example
+  4. Follow steps 4-9 of the regular release example

-# Features
-
-## Extending this section
-
-If your PR makes notable changes to Winit's features, please update this section as follows:
-
-- If your PR adds a new feature, add a brief description to the relevant section. If the feature is a core
-  feature, add a row to the feature matrix and describe what platforms the feature has been implemented on.
-
-- If your PR begins a new API rework, add a row to the `Pending API Reworks` table. If the PR implements the
-  API rework on all relevant platforms, please move it to the `Completed API Reworks` table.
-
-- If your PR implements an already-existing feature on a new platform, either mark the feature as *completed*,
-  or mark it as *mostly completed* and link to an issue describing the problems with the implementation.
-
-## Core
-
-### Windowing
-- **Window initialization**: Winit allows the creation of a window
-- **Providing pointer to init OpenGL**: Winit provides the necessary pointers to initialize a working opengl context
-- **Providing pointer to init Vulkan**: Same as OpenGL but for Vulkan
-- **Window decorations**: The windows created by winit are properly decorated, and the decorations can
-  be deactivated
-- **Window decorations toggle**: Decorations can be turned on or off after window creation
-- **Window resizing**: The windows created by winit can be resized and generate the appropriate events
-  when they are. The application can precisely control its window size if desired.
-- **Window resize increments**: When the window gets resized, the application can choose to snap the window's
-  size to specific values.
-- **Window transparency**: Winit allows the creation of windows with a transparent background.
-- **Window maximization**: The windows created by winit can be maximized upon creation.
-- **Window maximization toggle**: The windows created by winit can be maximized and unmaximized after
-  creation.
-- **Window minimization**: The windows created by winit can be minimized after creation.
-- **Fullscreen**: The windows created by winit can be put into fullscreen mode.
-- **Fullscreen toggle**: The windows created by winit can be switched to and from fullscreen after
-  creation.
-- **Exclusive fullscreen**: Winit allows changing the video mode of the monitor
-  for fullscreen windows, and if applicable, captures the monitor for exclusive
-  use by this application.
-- **HiDPI support**: Winit assists developers in appropriately scaling HiDPI content.
-- **Popup / modal windows**: Windows can be created relative to the client area of other windows, and parent
-  windows can be disabled in favor of popup windows. This feature also guarantees that popup windows
-  get drawn above their owner.
-
-
-### System Information
-- **Monitor list**: Retrieve the list of monitors and their metadata, including which one is primary.
-- **Video mode query**: Monitors can be queried for their supported fullscreen video modes (consisting of resolution, refresh rate, and bit depth).
-
-### Input Handling
-- **Mouse events**: Generating mouse events associated with pointer motion, click, and scrolling events.
-- **Mouse set location**: Forcibly changing the location of the pointer.
-- **Cursor locking**: Locking the cursor inside the window so it cannot move.
-- **Cursor confining**: Confining the cursor to the window bounds so it cannot leave them.
-- **Cursor icon**: Changing the cursor icon, or hiding the cursor.
-- **Cursor hittest**: Handle or ignore mouse events for a window.
-- **Touch events**: Single-touch events.
-- **Touch pressure**: Touch events contain information about the amount of force being applied.
-- **Multitouch**: Multi-touch events, including cancellation of a gesture.
-- **Keyboard events**: Properly processing keyboard events using the user-specified keymap and
-  translating keypresses into UTF-8 characters, handling dead keys and IMEs.
-- **Drag & Drop**: Dragging content into winit, detecting when content enters, drops, or if the drop is cancelled.
-- **Raw Device Events**: Capturing input from input devices without any OS filtering.
-- **Gamepad/Joystick events**: Capturing input from gamepads and joysticks.
-- **Device movement events**: Capturing input from the device gyroscope and accelerometer.

 ## Usage
 
 Winit is a window creation and management library. It can create windows and lets you handle
 events (for example: the window being resized, a key being pressed, a mouse movement, etc.)
-produced by window.
+produced by the window.
 
 Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to
 show something on the window you need to use the platform-specific getters provided by winit, or
 another library.
 
-```rust
-use winit::{
-    event::{Event, WindowEvent},
-    event_loop::{ControlFlow, EventLoop},
-    window::WindowBuilder,
-};
+## CONTRIBUTING
 
-fn main() {
-    let event_loop = EventLoop::new();
-    let window = WindowBuilder::new().build(&event_loop).unwrap();
+For contributing guidelines see [CONTRIBUTING.md](./CONTRIBUTING.md).
 
-    event_loop.run(move |event, _, control_flow| {
-        *control_flow = ControlFlow::Wait;
+## MSRV Policy
 
-        match event {
-            Event::WindowEvent {
-                event: WindowEvent::CloseRequested,
-                window_id,
-            } if window_id == window.id() => *control_flow = ControlFlow::Exit,
-            _ => (),
-        }

-}
+This crate's Minimum Supported Rust Version (MSRV) is **1.85**. Changes to
+the MSRV will be accompanied by a minor version bump.
+
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
+
+```
+min(sid, stable - 3)
 ```
 
-Winit is only officially supported on the latest stable version of the Rust compiler.
+Where `sid` is the current version of `rustc` provided by [Debian Sid], and
+`stable` is the latest stable version of Rust. This bound may be broken in case of a major ecosystem shift or a security vulnerability.
 
-### Cargo Features
+[Debian Sid]: https://packages.debian.org/sid/rustc
 
-Winit provides the following features, which can be enabled in your `Cargo.toml` file:
-* `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
-* `x11` (enabled by default): On Unix platform, compiles with the X11 backend
-* `wayland` (enabled by default): On Unix platform, compiles with the Wayland backend
-* `mint`: Enables mint (math interoperability standard types) conversions.
+An exception is made for the Android platform, where a higher Rust version
+must be used for certain Android features. In this case, the MSRV will be
+capped at the latest stable version of Rust minus three. This inconsistency is
+not reflected in Cargo metadata, as it is not powerful enough to expose this
+restriction.
+
+Redox OS is also not covered by this MSRV policy, as it requires a Rust nightly
+toolchain to compile.
+
+All crates in the [`rust-windowing`] organizations have the
+same MSRV policy.
+
+[`rust-windowing`]: https://github.com/rust-windowing
 
 ### Platform-specific usage
 
-#### Wayland
+Check out the [`winit::platform`](https://docs.rs/winit/latest/winit/platform/index.html) module for platform-specific usage.
 
-Note that windows don't appear on Wayland until you draw/present to them.
+### Repository License
 
-`winit` doesn't do drawing, try the examples in [`glutin`] instead.
-
-[`glutin`]: https://github.com/rust-windowing/glutin
-
-#### WebAssembly
-
-To run the web example: `cargo run-wasm --example web`
-
-Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
-
-On the web platform, a Winit window is backed by a `<canvas>` element. You can
-either [provide Winit with a `<canvas>` element][web with_canvas], or [let Winit
-create a `<canvas>` element which you can then retrieve][web canvas getter] and
-insert it into the DOM yourself.
-
-For example code using Winit with WebAssembly, check out the [web example]. For
-information on using Rust on WebAssembly, check out the [Rust and WebAssembly
-book].
-
-[web with_canvas]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowBuilderExtWebSys.html#tymethod.with_canvas

-[web example]: ./examples/web.rs
-[Rust and WebAssembly book]: https://rustwasm.github.io/book/
-
-#### Android
-
-The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/0.7.0/ndk/) crate.
-
-Native Android applications need some form of "glue" crate that is responsible
-for defining the main entry point for your Rust application as well as tracking
-various life-cycle events and synchronizing with the main JVM thread.
-
-Winit uses the [android-activity](https://github.com/rib/android-activity) as a
-glue crate (prior to `0.28` it used
-[ndk-glue](https://github.com/rust-windowing/android-ndk-rs/tree/master/ndk-glue)).
-
-The version of the glue crate that your application depends on _must_ match the
-version that Winit depends on because the glue crate is responsible for your
-application's main entrypoint. If Cargo resolves multiple versions they will
-clash.
-
-`winit` glue compatibility table:
-
-| winit |       ndk-glue               |
-| :---: | :--------------------------: |
-| 0.28  | `android-activity = "0.4"`   |
-| 0.27  | `ndk-glue = "0.7"`           |
-| 0.26  | `ndk-glue = "0.5"`           |
-| 0.25  | `ndk-glue = "0.3"`           |
-| 0.24  | `ndk-glue = "0.2"`           |
-
-The recommended way to avoid a conflict with the glue version is to avoid explicitly
-depending on the `android-activity` crate, and instead consume the API that
-is re-exported by Winit under `winit::platform::android::activity::*`
-
-Running on an Android device needs a dynamic system library, add this to Cargo.toml:
-
-```toml
-[lib]
-name = "main"
-crate-type = ["cdylib"]
-```
-
-All Android applications are based on an `Activity` subclass and the
-`android-activity` crate is designed to support different choices for this base
-class. Your application _must_ specify the base class it needs via a feature flag:
-
-| Base Class       | Feature Flag      |  Notes  |
-| :--------------: | :---------------: | :-----: |
-| `NativeActivity` | `android-native-activity` | Built-in to Android - it is possible to use without compiling any Java or Kotlin code. Java or Kotlin code may be needed to subclass `NativeActivity` to access some platform features. It does not derive from the [`AndroidAppCompat`] base class.|
-| [`GameActivity`] | `android-game-activity`   | Derives from [`AndroidAppCompat`] which is a defacto standard `Activity` base class that helps support a wider range of Android versions. Requires a build system that can compile Java or Kotlin and fetch Android dependencies from a [Maven repository][agdk_jetpack] (or link with an embedded [release][agdk_releases] of [`GameActivity`]) |
-
-[`GameActivity`]: https://developer.android.com/games/agdk/game-activity
-[`GameTextInput`]: https://developer.android.com/games/agdk/add-support-for-text-input
-[`AndroidAppCompat`]: https://developer.android.com/reference/androidx/appcompat/app/AppCompatActivity
-[agdk_jetpack]: https://developer.android.com/jetpack/androidx/releases/games
-[agdk_releases]: https://developer.android.com/games/agdk/download#agdk-libraries
-[Gradle]: https://developer.android.com/studio/build
-
-For example, add this to Cargo.toml:
-```toml
-winit = { version = "0.28", features = [ "android-native-activity" ] }
-
-[target.'cfg(target_os = "android")'.dependencies]
-android_logger = "0.11.0"
-```
-
-And, for example, define an entry point for your library like this:
-```rust
-#[cfg(target_os = "android")]
-use winit::platform::android::activity::AndroidApp;
-
-#[cfg(target_os = "android")]
-#[no_mangle]
-fn android_main(app: AndroidApp) {
-    use winit::platform::android::EventLoopBuilderExtAndroid;
-
-    android_logger::init_once(android_logger::Config::default().with_min_level(log::Level::Trace));
-
-    let event_loop = EventLoopBuilder::with_user_event()
-        .with_android_app(app)
-        .build();
-    _main(event_loop);
-}
-```
-
-For more details, refer to these `android-activity` [example applications](https://github.com/rib/android-activity/tree/main/examples).
-
-##### Converting from `ndk-glue` to `android-activity`
-
-If your application is currently based on `NativeActivity` via the `ndk-glue` crate and building with `cargo apk` then the minimal changes would be:
-1. Remove `ndk-glue` from your `Cargo.toml`
-2. Enable the `"android-native-activity"` feature for Winit: `winit = { version = "0.28", features = [ "android-native-activity" ] }`
-3. Add an `android_main` entrypoint (as above), instead of using the '`[ndk_glue::main]` proc macro from `ndk-macros` (optionally add a dependency on `android_logger` and initialize logging as above).
-4. Pass a clone of the `AndroidApp` that your application receives to Winit when building your event loop (as shown above).
-
-#### MacOS
-
-A lot of functionality expects the application to be ready before you start
-doing anything; this includes creating windows, fetching monitors, drawing,
-and so on, see issues [#2238], [#2051] and [#2087].
-
-If you encounter problems, you should try doing your initialization inside
-`Event::NewEvents(StartCause::Init)`.
-
-#### iOS
-
-Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
-by all UI related code, see issue [#1705]. You should consider creating your windows
-inside `Event::NewEvents(StartCause::Init)`.
-

-#### Redox OS
-
-Redox OS has some functionality not present yet, that will be implemented when
-its orbital display server provides it.

+## License
+
+Most of DPI is licensed under the Apache License, Version 2.0 ([LICENSE](LICENSE)).
+All files except for `src/libm.rs` (and `LICENSE-LIBM-MIT`) are available solely under that license.
+
+For its `no_std` support, DPI uses code from the [libm](https://crates.io/crates/libm) crate.
+This is in the `libm.rs` file, and is licensed solely under the MIT Licence ([LICENSE-LIBM-MIT](LICENSE-LIBM-MIT)).
+That file contains details of all potentially applicable copyright notices.
+This is feature gated to only be included if you disable the `std` feature, otherwise it will not be compiled into your final binary
+(and so these license terms will not apply).
+
+Overall, this means that the license for this crate depends on what features you have enabled.
+If you enable the `std` feature, then DPI uses only code available under the Apache-2.0 license, and so can be used under the terms of that license.
+However, if you disable the `std` feature, then both these licenses must be followed to use the crate as a whole.

-When moving fingers on a trackpad down and to the right, you should see positive X and Y deltas, and the window should move down and to the right.

-With reverse scrolling, you should see the inverse behavior.

-This example draws a circle in the middle of a 4/1 aspect ratio canvas which acts as a useful demonstration of winit's resize handling on web.
-Even when the browser window is resized or aspect-ratio of the canvas changed the circle should always:
-* Fill the entire width or height of the canvas (whichever is smaller) without exceeding it.
-* Be perfectly round
-* Not be blurry or pixelated (there is no antialiasing so you may still see jagged edges depending on the DPI of your monitor)
-
-Currently winit does not handle resizes on web so the circle is rendered incorrectly.
-This example demonstrates the desired future functionality which will possibly be provided by https://github.com/rust-windowing/winit/pull/2074

-//! UI scaling is important, so read the docs for this module if you don't want to be confused.
-//!
-//! ## Why should I care about UI scaling?
-//!
-//! Modern computer screens don't have a consistent relationship between resolution and size.
-//! 1920x1080 is a common resolution for both desktop and mobile screens, despite mobile screens
-//! normally being less than a quarter the size of their desktop counterparts. What's more, neither
-//! desktop nor mobile screens are consistent resolutions within their own size classes - common
-//! mobile screens range from below 720p to above 1440p, and desktop screens range from 720p to 5K
-//! and beyond.
-//!
-//! Given that, it's a mistake to assume that 2D content will only be displayed on screens with
-//! a consistent pixel density. If you were to render a 96-pixel-square image on a 1080p screen,
-//! then render the same image on a similarly-sized 4K screen, the 4K rendition would only take up
-//! about a quarter of the physical space as it did on the 1080p screen. That issue is especially
-//! problematic with text rendering, where quarter-sized text becomes a significant legibility
-//! problem.
-//!
-//! Failure to account for the scale factor can create a significantly degraded user experience.
-//! Most notably, it can make users feel like they have bad eyesight, which will potentially cause
-//! them to think about growing elderly, resulting in them having an existential crisis. Once users
-//! enter that state, they will no longer be focused on your application.
-//!
-//! ## How should I handle it?
-//!
-//! The solution to this problem is to account for the device's *scale factor*. The scale factor is
-//! the factor UI elements should be scaled by to be consistent with the rest of the user's system -
-//! for example, a button that's normally 50 pixels across would be 100 pixels across on a device
-//! with a scale factor of `2.0`, or 75 pixels across with a scale factor of `1.5`.
-//!
-//! Many UI systems, such as CSS, expose DPI-dependent units like [points] or [picas]. That's
-//! usually a mistake, since there's no consistent mapping between the scale factor and the screen's
-//! actual DPI. Unless you're printing to a physical medium, you should work in scaled pixels rather
-//! than any DPI-dependent units.
-//!
-//! ### Position and Size types
-//!
-//! Winit's [`PhysicalPosition`] / [`PhysicalSize`] types correspond with the actual pixels on the
-//! device, and the [`LogicalPosition`] / [`LogicalSize`] types correspond to the physical pixels
-//! divided by the scale factor.
-//! All of Winit's functions return physical types, but can take either logical or physical
-//! coordinates as input, allowing you to use the most convenient coordinate system for your
-//! particular application.
-//!
-//! Winit's position and size types types are generic over their exact pixel type, `P`, to allow the
-//! API to have integer precision where appropriate (e.g. most window manipulation functions) and
-//! floating precision when necessary (e.g. logical sizes for fractional scale factors and touch
-//! input). If `P` is a floating-point type, please do not cast the values with `as {int}`. Doing so
-//! will truncate the fractional part of the float, rather than properly round to the nearest
-//! integer. Use the provided `cast` function or [`From`]/[`Into`] conversions, which handle the
-//! rounding properly. Note that precision loss will still occur when rounding from a float to an
-//! int, although rounding lessens the problem.
-//!
-//! ### Events
-//!
-//! Winit will dispatch a [`ScaleFactorChanged`] event whenever a window's scale factor has changed.
-//! This can happen if the user drags their window from a standard-resolution monitor to a high-DPI
-//! monitor, or if the user changes their DPI settings. This gives you a chance to rescale your
-//! application's UI elements and adjust how the platform changes the window's size to reflect the new
-//! scale factor. If a window hasn't received a [`ScaleFactorChanged`] event,  then its scale factor
-//! can be found by calling [`window.scale_factor()`].
-//!
-//! ## How is the scale factor calculated?
-//!
-//! Scale factor is calculated differently on different platforms:
-//!
-//! - **Windows:** On Windows 8 and 10, per-monitor scaling is readily configured by users from the
-//!   display settings. While users are free to select any option they want, they're only given a
-//!   selection of "nice" scale factors, i.e. 1.0, 1.25, 1.5... on Windows 7, the scale factor is
-//!   global and changing it requires logging out. See [this article][windows_1] for technical
-//!   details.
-//! - **macOS:** Recent versions of macOS allow the user to change the scaling factor for certain
-//!   displays. When this is available, the user may pick a per-monitor scaling factor from a set
-//!   of 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.
-//!   + 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:** On Wayland, scale factors are set per-screen by the server, and are always
-//!   integers (most often 1 or 2).
-//! - **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
-//!   information.
-//! - **Android:** Scale factors are set by the manufacturer to the value that best suits the
-//!   device, and range from `1.0` to `4.0`. See [this article][android_1] for more information.
-//! - **Web:** The scale factor is the ratio between CSS pixels and the physical device pixels.
-//!   In other words, it is the value of [`window.devicePixelRatio`][web_1]. It is affected by
-//!   both the screen scaling and the browser zoom level and can go below `1.0`.

-//! Winit is a cross-platform window creation and event loop management library.
-//!
-//! # Building windows
-//!
-//! Before you can build a [`Window`], you first need to build an [`EventLoop`]. This is done with the
-//! [`EventLoop::new()`] function.
-//!
-//! ```no_run
-//! use winit::event_loop::EventLoop;
-//! let event_loop = EventLoop::new();
-//! ```
-//!
-//! Once this is done there are two ways to create a [`Window`]:
-//!
-//!  - Calling [`Window::new(&event_loop)`][window_new].
-//!  - Calling [`let builder = WindowBuilder::new()`][window_builder_new] then [`builder.build(&event_loop)`][window_builder_build].
-//!
-//! The first method is the simplest, and will give you default values for everything. The second
-//! method allows you to customize the way your [`Window`] will look and behave by modifying the
-//! fields of the [`WindowBuilder`] object before you create the [`Window`].
-//!
-//! # Event handling
-//!
-//! Once a [`Window`] has been created, it will generate different *events*. A [`Window`] object can
-//! generate [`WindowEvent`]s when certain input events occur, such as a cursor moving over the
-//! window or a key getting pressed while the window is focused. Devices can generate
-//! [`DeviceEvent`]s, which contain unfiltered event data that isn't specific to a certain window.
-//! Some user activity, like mouse movement, can generate both a [`WindowEvent`] *and* a
-//! [`DeviceEvent`]. You can also create and handle your own custom [`UserEvent`]s, if desired.
-//!
-//! You can retrieve events by calling [`EventLoop::run`][event_loop_run]. This function will
-//! dispatch events for every [`Window`] that was created with that particular [`EventLoop`], and
-//! will run until the `control_flow` argument given to the closure is set to
-//! [`ControlFlow`]`::`[`ExitWithCode`] (which [`ControlFlow`]`::`[`Exit`] aliases to), at which
-//! point [`Event`]`::`[`LoopDestroyed`] is emitted and the entire program terminates.
-//!
-//! Winit no longer uses a `EventLoop::poll_events() -> impl Iterator<Event>`-based event loop
-//! model, since that can't be implemented properly on some platforms (e.g web, iOS) and works poorly on
-//! most other platforms. However, this model can be re-implemented to an extent with
-//! [`EventLoopExtRunReturn::run_return`]. See that method's documentation for more reasons about why
-//! it's discouraged, beyond compatibility reasons.
-//!
-//!
-//! ```no_run
-//! use winit::{
-//!     event::{Event, WindowEvent},
-//!     event_loop::EventLoop,
-//!     window::WindowBuilder,
-//! };
-//!
-//! let event_loop = EventLoop::new();
-//! let window = WindowBuilder::new().build(&event_loop).unwrap();
-//!
-//! event_loop.run(move |event, _, control_flow| {
-//!     // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
-//!     // dispatched any events. This is ideal for games and similar applications.
-//!     control_flow.set_poll();
-//!
-//!     // ControlFlow::Wait pauses the event loop if no events are available to process.
-//!     // This is ideal for non-game applications that only update in response to user
-//!     // input, and uses significantly less power/CPU time than ControlFlow::Poll.
-//!     control_flow.set_wait();
-//!
-//!     match event {
-//!         Event::WindowEvent {
-//!             event: WindowEvent::CloseRequested,
-//!             ..
-//!         } => {
-//!             println!("The close button was pressed; stopping");
-//!             control_flow.set_exit();
-//!         },
-//!         Event::MainEventsCleared => {
-//!             // Application update code.
-//!
-//!             // Queue a RedrawRequested event.
-//!             //
-//!             // You only need to call this if you've determined that you need to redraw, in
-//!             // applications which do not always need to. Applications that redraw continuously
-//!             // can just render here instead.
-//!             window.request_redraw();
-//!         },
-//!         Event::RedrawRequested(_) => {
-//!             // Redraw the application.
-//!             //
-//!             // It's preferable for applications that do not render continuously to render in
-//!             // this event rather than in MainEventsCleared, since rendering in here allows
-//!             // the program to gracefully handle redraws requested by the OS.
-//!         },
-//!         _ => ()
-//!     }
-//! });
-//! ```
-//!
-//! [`Event`]`::`[`WindowEvent`] has a [`WindowId`] member. In multi-window environments, it should be
-//! compared to the value returned by [`Window::id()`][window_id_fn] to determine which [`Window`]
-//! dispatched the event.
-//!
-//! # Drawing on the window
-//!
-//! Winit doesn't directly provide any methods for drawing on a [`Window`]. However it allows you to
-//! retrieve the raw handle of the window and display (see the [`platform`] module and/or the
-//! [`raw_window_handle`] and [`raw_display_handle`] methods), which in turn allows
-//!  you to create an OpenGL/Vulkan/DirectX/Metal/etc. context that can be used to render graphics.
-//!
-//! Note that many platforms will display garbage data in the window's client area if the
-//! application doesn't render anything to the window by the time the desktop compositor is ready to
-//! display the window to the user. If you notice this happening, you should create the window with
-//! [`visible` set to `false`](crate::window::WindowBuilder::with_visible) and explicitly make the
-//! window visible only once you're ready to render into it.

-//! iOS support
-//!
-//! # Building app
-//! To build ios app you will need rustc built for this targets:
-//!
-//!  - armv7-apple-ios
-//!  - armv7s-apple-ios
-//!  - i386-apple-ios
-//!  - aarch64-apple-ios
-//!  - x86_64-apple-ios
-//!
-//! Then
-//!
-//! ```
-//! cargo build --target=...
-//! ```
-//! The simplest way to integrate your app into xcode environment is to build it
-//! as a static library. Wrap your main function and export it.
-//!
-//! ```rust, ignore
-//! #[no_mangle]
-//! pub extern fn start_winit_app() {
-//!     start_inner()
-//! }
-//!
-//! fn start_inner() {
-//!    ...
-//! }
-//! ```
-//!
-//! Compile project and then drag resulting .a into Xcode project. Add winit.h to xcode.
-//!
-//! ```ignore
-//! void start_winit_app();
-//! ```
-//!
-//! Use start_winit_app inside your xcode's main function.
-//!
-//!
-//! # App lifecycle and events
-//!
-//! iOS environment is very different from other platforms and you must be very
-//! careful with it's events. Familiarize yourself with
-//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
-//!
-//!
-//! This is how those event are represented in winit:
-//!
-//!  - applicationDidBecomeActive is Resumed
-//!  - applicationWillResignActive is Suspended
-//!  - applicationWillTerminate is LoopDestroyed
-//!
-//! Keep in mind that after LoopDestroyed event is received every attempt to draw with
-//! opengl will result in segfault.
-//!
-//! Also note that app may not receive the LoopDestroyed event if suspended; it might be SIGKILL'ed.
