+master docs][master_docs].
 
-# 0.26.0 (2021-12-01)
-
-- Update `raw-window-handle` to `v0.4`. This is _not_ a breaking change, we still implement `HasRawWindowHandle` from `v0.3`, see [rust-windowing/raw-window-handle#74](https://github.com/rust-windowing/raw-window-handle/pull/74). Note that you might have to run `cargo update -p raw-window-handle` after upgrading.
-- On X11, bump `mio` to 0.8.
-- On Android, fixed `WindowExtAndroid::config` initially returning an empty `Configuration`.
-- On Android, fixed `Window::scale_factor` and `MonitorHandle::scale_factor` initially always returning 1.0.
-- On X11, select an appropriate visual for transparency if is requested
-- On Wayland and X11, fix diagonal window resize cursor orientation.
-- On macOS, drop the event callback before exiting.
-- On Android, implement `Window::request_redraw`
-- **Breaking:** On Web, remove the `stdweb` backend.
-- Added `Window::focus_window`to bring the window to the front and set input focus.
-- On Wayland and X11, implement `is_maximized` method on `Window`.
-- On Windows, prevent ghost window from showing up in the taskbar after either several hours of use or restarting `explorer.exe`.
-- On macOS, fix issue where `ReceivedCharacter` was not being emitted during some key repeat events.
-- On Wayland, load cursor icons `hand2` and `hand1` for `CursorIcon::Hand`.
-- **Breaking:** On Wayland, Theme trait and its support types are dropped.
-- On Wayland, bump `smithay-client-toolkit` to 0.15.1.
-- On Wayland, implement `request_user_attention` with `xdg_activation_v1`.
-- On X11, emit missing `WindowEvent::ScaleFactorChanged` when the only monitor gets reconnected.
-- On X11, if RANDR based scale factor is higher than 20 reset it to 1
-- On Wayland, add an enabled-by-default feature called `wayland-dlopen` so users can opt out of using `dlopen` to load system libraries.
-- **Breaking:** On Android, bump `ndk` and `ndk-glue` to 0.5.
-- On Windows, increase wait timer resolution for more accurate timing when using `WaitUntil`.
-- On macOS, fix native file dialogs hanging the event loop.
-- On Wayland, implement a workaround for wrong configure size when using `xdg_decoration` in `kwin_wayland`
-- On macOS, fix an issue that prevented the menu bar from showing in borderless fullscreen mode.
-- On X11, EINTR while polling for events no longer causes a panic. Instead it will be treated as a spurious wakeup.
-
-# 0.25.0 (2021-05-15)
-
-- **Breaking:** On macOS, replace `WindowBuilderExtMacOS::with_activation_policy` with `EventLoopExtMacOS::set_activation_policy`
-- On macOS, wait with activating the application until the application has initialized.
-- On macOS, fix creating new windows when the application has a main menu.
-- On Windows, fix fractional deltas for mouse wheel device events.
-- On macOS, fix segmentation fault after dropping the main window.
-- On Android, `InputEvent::KeyEvent` is partially implemented providing the key scancode.
-- Added `is_maximized` method to `Window`.
-- On Windows, fix bug where clicking the decoration bar would make the cursor blink.
-- On Windows, fix bug causing newly created windows to erroneously display the "wait" (spinning) cursor.
-- On macOS, wake up the event loop immediately when a redraw is requested.
-- On Windows, change the default window size (1024x768) to match the default on other desktop platforms (800x600).
-- On Windows, fix bug causing mouse capture to not be released.
-- On Windows, fix fullscreen not preserving minimized/maximized state.
-- On Android, unimplemented events are marked as unhandled on the native event loop.
-- On Windows, added `WindowBuilderExtWindows::with_menu` to set a custom menu at window creation time.
-- On Android, bump `ndk` and `ndk-glue` to 0.3: use predefined constants for event `ident`.
-- On macOS, fix objects captured by the event loop closure not being dropped on panic.
-- On Windows, fixed `WindowEvent::ThemeChanged` not properly firing and fixed `Window::theme` returning the wrong theme.
-- On Web, added support for `DeviceEvent::MouseMotion` to listen for relative mouse movements.
-- Added `WindowBuilder::with_position` to allow setting the position of a `Window` on creation. Supported on Windows, macOS and X11.
-- Added `Window::drag_window`. Implemented on Windows, macOS, X11 and Wayland.
-- On X11, bump `mio` to 0.7.
-- On Windows, added `WindowBuilderExtWindows::with_owner_window` to allow creating popup windows.

-- On macOS, emit `RedrawRequested` events immediately while the window is being resized.
-- Implement `Default`, `Hash`, and `Eq` for `LogicalPosition`, `PhysicalPosition`, `LogicalSize`, and `PhysicalSize`.
-- On macOS, initialize the Menu Bar with minimal defaults. (Can be prevented using `enable_default_menu_creation`)
-- On macOS, change the default behavior for first click when the window was unfocused. Now the window becomes focused and then emits a `MouseInput` event on a "first mouse click".
-- Implement mint (math interoperability standard types) conversions (under feature flag `mint`).

-  - **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.

-# 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
+### Submitting your work and handling review
 
-## Making a pull request
+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.
 
-When making a code contribution to winit, before opening your pull request, please make sure that:
+#### Handling review
 
-- 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
-- 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.
+During the review process certain events could require an action from your side,
+common patterns and reactions are described below.
 
-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).
+_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.
 
-## Maintainers & Testers
+_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.
 
-The current [list of testers and contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors)
-can be found on the Wiki.
+_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.
 
-If you are interested in contributing or testing on a platform, please add yourself to that table!

+
+## 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`
+  2. A new `v0.2.x` branch is created for the release
+  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:

-# 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 grab**: Locking the cursor so it cannot exit the client area of a window.
-- **Cursor icon**: Changing the cursor icon, or hiding the cursor.
-- **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,
-};
+## MSRV Policy
 
-fn main() {
-    let event_loop = EventLoop::new();
-    let window = WindowBuilder::new().build(&event_loop).unwrap();
+This crate's Minimum Supported Rust Version (MSRV) is **1.73**. Changes to
+the MSRV will be accompanied by a minor version bump.
 
-    event_loop.run(move |event, _, control_flow| {
-        *control_flow = ControlFlow::Wait;
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
 
-        match event {
-            Event::WindowEvent {
-                event: WindowEvent::CloseRequested,
-                window_id,
-            } if window_id == window.id() => *control_flow = ControlFlow::Exit,
-            _ => (),
-        }
-    });
-}
+```
+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.

 ### Platform-specific usage
 
-#### WebAssembly
-
-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 canvas getter]: https://docs.rs/winit/latest/wasm32-unknown-unknown/winit/platform/web/trait.WindowExtWebSys.html#tymethod.canvas
-[web example]: ./examples/web.rs
-[Rust and WebAssembly book]: https://rustwasm.github.io/book/
-
-#### Android
-
-This library makes use of the [ndk-rs](https://github.com/rust-windowing/android-ndk-rs) crates, refer to that repo for more documentation.
-
-The `ndk_glue` version needs to match the version used by `winit`. Otherwise, the application will not start correctly as `ndk_glue`'s internal NativeActivity static is not the same due to version mismatch.
-
-`ndk_glue` <-> `winit` version comparison compatibility:
-
-| winit |       ndk_glue       |
-| :---: | :------------------: |
-| 0.24  | `ndk_glue = "0.2.0"` |
-| 0.25  | `ndk_glue = "0.3.0"` |
-| 0.26  | `ndk_glue = "0.5.0"` |
-
-Running on an Android device needs a dynamic system library, add this to Cargo.toml:
-
-```toml
-[[example]]
-name = "request_redraw_threaded"
-crate-type = ["cdylib"]
-```
-
-And add this to the example file to add the native activity glue:
-```rust
-#[cfg_attr(target_os = "android", ndk_glue::main(backtrace = "on"))]
-fn main() {
-    ...
-}
-```
-
-And run the application with `cargo apk run --example request_redraw_threaded`
-
-#### MacOS
-
-To ensure compatibility with older MacOS systems, winit links to
-CGDisplayCreateUUIDFromDisplayID through the CoreGraphics framework.
-However, under certain setups this function is only available to be linked
-through the newer ColorSync framework. So, winit provides the
-`WINIT_LINK_COLORSYNC` environment variable which can be set to `1` or `true`
-while compiling to enable linking via ColorSync.
-
+Check out the [`winit::platform`](https://docs.rs/winit/latest/winit/platform/index.html) module for platform-specific usage.

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+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
+
+- Added `Insets`, `LogicalInsets` and `PhysicalInsets` types.
+
+## 0.1.1
+
+- Derive `Debug`, `Copy`, `Clone`, `PartialEq`, `Serialize`, `Deserialize` traits for `PixelUnit`.
+
+## 0.1.0
+
+- Add `LogicalUnit`, `PhysicalUnit` and `PixelUnit` types and related functions.

+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+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:
+
+```md
+### 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:
+
+```md
+- 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()`.
+- On Web, add `ActiveEventLoopExtWeb::is_cursor_lock_raw()` to determine if
+  `DeviceEvent::MouseMotion` is returning raw data, not OS accelerated, when using
+  `CursorGrabMode::Locked`.
+- On Web, implement `MonitorHandle` and `VideoModeHandle`.
+
+  Without prompting the user for permission, only the current monitor is returned. But when
+  prompting and being granted permission through
+  `ActiveEventLoop::request_detailed_monitor_permission()`, access to all monitors and their
+  details is available. Handles created with "detailed monitor permissions" can be used in
+  `Window::set_fullscreen()` as well.
+
+  Keep in mind that handles do not auto-upgrade after permissions are granted and have to be
+  re-created to make full use of this feature.
+- Implement `Clone`, `Copy`, `Debug`, `Deserialize`, `Eq`, `Hash`, `Ord`, `PartialEq`, `PartialOrd`
+  and `Serialize` on many types.
+- Add `MonitorHandle::current_video_mode()`.
+- On Android, the soft keyboard can now be shown using `Window::set_ime_allowed`.
+- Add basic iOS IME support. The soft keyboard can now be shown using `Window::set_ime_allowed`.
+- Add `ApplicationHandlerExtMacOS` trait, and a `macos_handler` method to `ApplicationHandler` which returns a `dyn ApplicationHandlerExtMacOS` which allows for macOS specific extensions to winit.
+- Add a `standard_key_binding` method to the `ApplicationHandlerExtMacOS` trait. This allows handling of standard keybindings such as "go to end of line" on macOS.
+- On macOS, add `WindowExtMacOS::set_borderless_game` and `WindowAttributesExtMacOS::with_borderless_game`
+  to fully disable the menu bar and dock in Borderless Fullscreen as commonly done in games.
+- On macOS, add `WindowExtMacOS::set_unified_titlebar` and `WindowAttributesExtMacOS::with_unified_titlebar`
+  to use a larger style of titlebar.
+- Add `WindowId::into_raw()` and `from_raw()`.
+- Add `PointerKind`, `PointerSource`, `ButtonSource`, `FingerId`, `primary` and `position` to all
+  pointer events as part of the pointer event overhaul.
+- Add `DeviceId::into_raw()` and `from_raw()`.
+- On X11, the `window` example now understands the `X11_VISUAL_ID` and `X11_SCREEN_ID` env
+  variables to test the respective modifiers of window creation.
+- Added `Window::surface_position`, which is the position of the surface inside the window.
+- Added `Window::safe_area`, which describes the area of the surface that is unobstructed.
+- On X11, Wayland, Windows and macOS, improved scancode conversions for more obscure key codes.
+
+### Changed
+
+- Change `ActiveEventLoop` to be a trait.
+- Change `Window` to be a trait.
+- `ActiveEventLoop::create_window` now returns `Box<dyn Window>`.
+- `ApplicationHandler` now uses `dyn ActiveEventLoop`.
+- 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.
+- On X11, implement smooth resizing through the sync extension API.
+- `ApplicationHandler::can_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, Web
+  and Android, 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.
+- On Web, `Window::canvas()` now returns a reference.
+- On Web, `CursorGrabMode::Locked` now lets `DeviceEvent::MouseMotion` return raw data, not OS
+  accelerated, if the browser supports it.
+- `(Active)EventLoop::create_custom_cursor()` now returns a `Result<CustomCursor, ExternalError>`.
+- Changed how `ModifiersState` is serialized by Serde.
+- `VideoModeHandle::refresh_rate_millihertz()` and `bit_depth()` now return a `Option<NonZero*>`.
+- `MonitorHandle::position()` now returns an `Option`.
+- On iOS and macOS, remove custom application delegates. You are now allowed to override the
+  application delegate yourself.
+- On iOS, no longer act as-if the application successfully open all URLs. Override
+  `application:didFinishLaunchingWithOptions:` and provide the desired behaviour yourself.
+- On X11, remove our dependency on libXcursor. (#3749)
+- Renamed the following APIs to make it clearer that the sizes apply to the underlying surface:
+  - `WindowEvent::Resized` to `SurfaceResized`.
+  - `InnerSizeWriter` to `SurfaceSizeWriter`.
+  - `WindowAttributes.inner_size` to `surface_size`.
+  - `WindowAttributes.min_inner_size` to `min_surface_size`.
+  - `WindowAttributes.max_inner_size` to `max_surface_size`.
+  - `WindowAttributes.resize_increments` to `surface_resize_increments`.
+  - `WindowAttributes::with_inner_size` to `with_surface_size`.
+  - `WindowAttributes::with_min_inner_size` to `with_min_surface_size`.
+  - `WindowAttributes::with_max_inner_size` to `with_max_surface_size`.
+  - `WindowAttributes::with_resize_increments` to `with_surface_resize_increments`.
+  - `Window::inner_size` to `surface_size`.
+  - `Window::request_inner_size` to `request_surface_size`.
+  - `Window::set_min_inner_size` to `set_min_surface_size`.
+  - `Window::set_max_inner_size` to `set_max_surface_size`.
+
+  To migrate, you can probably just replace all instances of `inner_size` with `surface_size` in your codebase.
+- Every event carrying a `DeviceId` now uses `Option<DeviceId>` instead. A `None` value signifies that the
+  device can't be uniquely identified.
+- Pointer `WindowEvent`s were overhauled. The new events can handle any type of pointer, serving as
+  a single pointer input source. Now your application can handle any pointer type without having to
+  explicitly handle e.g. `Touch`:
+  - Rename `CursorMoved` to `PointerMoved`.
+  - Rename `CursorEntered` to `PointerEntered`.
+  - Rename `CursorLeft` to `PointerLeft`.
+  - Rename `MouseInput` to `PointerButton`.
+  - Add `primary` to every `PointerEvent` as a way to identify discard non-primary pointers in a
+    multi-touch interaction.
+  - Add `position` to every `PointerEvent`.
+  - `PointerMoved` is **not sent** after `PointerEntered` anymore.
+  - Remove `Touch`, which is folded into the `Pointer*` events.
+  - New `PointerKind` added to `PointerEntered` and `PointerLeft`, signifying which pointer type is
+    the source of this event.
+  - New `PointerSource` added to `PointerMoved`, similar to `PointerKind` but holding additional
+    data.
+  - New `ButtonSource` added to `PointerButton`, similar to `PointerKind` but holding pointer type
+    specific buttons. Use `ButtonSource::mouse_button()` to easily normalize any pointer button
+    type to a generic mouse button.
+  - New `FingerId` added to `PointerKind::Touch` and `PointerSource::Touch` able to uniquely
+    identify a finger in a multi-touch interaction. Replaces the old `Touch::id`.
+  - In the same spirit rename `DeviceEvent::MouseMotion` to `PointerMotion`.
+  - Remove `Force::Calibrated::altitude_angle`.
+- On X11, use bottom-right corner for IME hotspot in `Window::set_ime_cursor_area`.
+- On macOS and iOS, no longer emit `ScaleFactorChanged` upon window creation.
+- On macOS, no longer emit `Focused` upon window creation.
+- On iOS, emit more events immediately, instead of queuing them.
+- Update `smol_str` to version `0.3`
+
+### Removed
+
+- Remove `Event`.
+- Remove already deprecated APIs:
+  - `EventLoop::create_window()`
+  - `EventLoop::run`.
+  - `EventLoopBuilder::new()`
+  - `EventLoopExtPumpEvents::pump_events`.
+  - `EventLoopExtRunOnDemand::run_on_demand`.
+  - `VideoMode`
+  - `WindowAttributes::new()`
+  - `Window::set_cursor_icon()`
+- 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()`.
+- On Web, remove unused `platform::web::CustomCursorError::Animation`.
+- Remove the `rwh_04` and `rwh_05` cargo feature and the corresponding `raw-window-handle` v0.4 and
+  v0.5 support. v0.6 remains in place and is enabled by default.
+- Remove `DeviceEvent::Added` and `DeviceEvent::Removed`.
+- Remove `DeviceEvent::Motion` and `WindowEvent::AxisMotion`.
+- Remove `MonitorHandle::size()` and `refresh_rate_millihertz()` in favor of
+  `MonitorHandle::current_video_mode()`.
+- On Android, remove all `MonitorHandle` support instead of emitting false data.
+- Remove `impl From<u64> for WindowId` and `impl From<WindowId> for u64`. Replaced with
+  `WindowId::into_raw()` and `from_raw()`.
+- Remove `dummy()` from `WindowId` and `DeviceId`.
+- Remove `WindowEvent::Touch` and `Touch` in favor of the new `PointerKind`, `PointerSource` and
+ `ButtonSource` as part of the new pointer event overhaul.
+- Remove `Force::altitude_angle`.
+- Removed `Window::inner_position`, use the new `Window::surface_position` instead.
+
+### Fixed
+
+- On Orbital, `MonitorHandle::name()` now returns `None` instead of a dummy name.
+- On macOS, fix `WindowEvent::Moved` sometimes being triggered unnecessarily on resize.
+- On macOS, package manifest definitions of `LSUIElement` will no longer be overridden with the
+  default activation policy, unless explicitly provided during initialization.
+- On macOS, fix crash when calling `drag_window()` without a left click present.
+- On X11, key events forward to IME anyway, even when it's disabled.
+- On Windows, make `ControlFlow::WaitUntil` work more precisely using `CREATE_WAITABLE_TIMER_HIGH_RESOLUTION`.
+- On X11, creating windows on screen that is not the first one (e.g. `DISPLAY=:0.1`) works again.
+- On X11, creating windows while passing `with_x11_screen(non_default_screen)` works again.
+- On X11, fix XInput handling that prevented a new window from getting the focus in some cases.
+- On iOS, fixed `SurfaceResized` and `Window::surface_size` not reporting the size of the actual surface.
+- On macOS, fixed the scancode conversion for audio volume keys.
+- On macOS, fixed the scancode conversion for `IntlBackslash`.
+- On macOS, fixed redundant `SurfaceResized` event at window creation.
+- On macOS, fix crash when pressing Caps Lock in certain configurations.
+- On iOS, fixed `MonitorHandle`'s `PartialEq` and `Hash` implementations.

+- **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.

+- 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.

+- 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.

+- 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`.

+- 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`.

+- **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.

+- 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`.

+- 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.
+
+## 0.16.1
+
+- 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.
+
+## 0.16.0
+
+- 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 `?`.

+
+## 0.20.0-alpha1
+
+- 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.
+- Remove `WindowBuilder::multitouch` field, since it was only implemented on a few platforms. Multitouch is always enabled now.
+- **Breaking:** On macOS, change `ns` identifiers to use snake_case for consistency with iOS's `ui` identifiers.
+- Add `MonitorHandle::video_modes` method for retrieving supported video modes for the given monitor.
+- On Wayland, the window now exists even if nothing has been drawn.
+- On Windows, fix initial dimensions of a fullscreen window.
+- On Windows, Fix transparent borderless windows rendering wrong.

+- Add `EventLoopBuilder`, which allows you to create and tweak the settings of an event loop before creating it.
+- Deprecated `EventLoop::with_user_event`; use `EventLoopBuilder::with_user_event` instead.
+- **Breaking:** Replaced `EventLoopExtMacOS` with `EventLoopBuilderExtMacOS` (which also has renamed methods).
+- **Breaking:** Replaced `EventLoopExtWindows` with `EventLoopBuilderExtWindows` (which also has renamed methods).
+- **Breaking:** Replaced `EventLoopExtUnix` with `EventLoopBuilderExtUnix` (which also has renamed methods).
+- **Breaking:** The platform specific extensions for Windows `winit::platform::windows` have changed. All `HANDLE`-like types e.g. `HWND` and `HMENU` were converted from winapi types or `*mut c_void` to `isize`. This was done to be consistent with the type definitions in windows-sys and to not expose internal dependencies.
+- The internal bindings to the [Windows API](https://docs.microsoft.com/en-us/windows/) were changed from the unofficial [winapi](https://github.com/retep998/winapi-rs) bindings to the official Microsoft [windows-sys](https://github.com/microsoft/windows-rs) bindings.
+- On Wayland, fix polling during consecutive `EventLoop::run_return` invocations.
+- On Windows, fix race issue creating fullscreen windows with `WindowBuilder::with_fullscreen`
+- On Android, `virtual_keycode` for `KeyboardInput` events is now filled in where a suitable match is found.
+- Added helper methods on `ControlFlow` to set its value.
+- On Wayland, fix `TouchPhase::Ended` always reporting the location of the first touch down, unless the compositor
+  sent a cancel or frame event.
+- On iOS, send `RedrawEventsCleared` even if there are no redraw events, consistent with other platforms.
+- **Breaking:** Replaced `Window::with_app_id` and `Window::with_class` with `Window::with_name` on `WindowBuilderExtUnix`.
+- On Wayland, fallback CSD was replaced with proper one:
+  - `WindowBuilderExtUnix::with_wayland_csd_theme` to set color theme in builder.
+  - `WindowExtUnix::wayland_set_csd_theme` to set color theme when creating a window.
+  - `WINIT_WAYLAND_CSD_THEME` env variable was added, it can be used to set "dark"/"light" theme in apps that don't expose theme setting.
+  - `wayland-csd-adwaita` feature that enables proper CSD with title rendering using FreeType system library.
+  - `wayland-csd-adwaita-notitle` feature that enables CSD but without title rendering.
+- On Wayland and X11, fix window not resizing with `Window::set_inner_size` after calling `Window:set_resizable(false)`.
+- On Windows, fix wrong fullscreen monitors being recognized when handling WM_WINDOWPOSCHANGING messages
+- **Breaking:** Added new `WindowEvent::Ime` supported on desktop platforms.
+- Added `Window::set_ime_allowed` supported on desktop platforms.
+- **Breaking:** IME input on desktop platforms won't be received unless it's explicitly allowed via `Window::set_ime_allowed` and new `WindowEvent::Ime` events are handled.
+- On macOS, `WindowEvent::Resized` is now emitted in `frameDidChange` instead of `windowDidResize`.
+- **Breaking:** On X11, device events are now ignored for unfocused windows by default, use `EventLoopWindowTarget::set_device_event_filter` to set the filter level.
+- Implemented `Default` on `EventLoop<()>`.
+- Implemented `Eq` for `Fullscreen`, `Theme`, and `UserAttentionType`.
+- **Breaking:** `Window::set_cursor_grab` now accepts `CursorGrabMode` to control grabbing behavior.
+- On Wayland, add support for `Window::set_cursor_position`.
+- Fix on macOS `WindowBuilder::with_disallow_hidpi`, setting true or false by the user no matter the SO default value.
+- `EventLoopBuilder::build` will now panic when the `EventLoop` is being created more than once.
+- Added `From<u64>` for `WindowId` and `From<WindowId>` for `u64`.
+- Added `MonitorHandle::refresh_rate_millihertz` to get monitor's refresh rate.
+- **Breaking**, Replaced `VideoMode::refresh_rate` with `VideoMode::refresh_rate_millihertz` providing better precision.
+- On Web, add `with_prevent_default` and `with_focusable` to `WindowBuilderExtWebSys` to control whether events should be propagated.
+- On Windows, fix focus events being sent to inactive windows.
+- **Breaking**, update `raw-window-handle` to `v0.5` and implement `HasRawDisplayHandle` for `Window` and `EventLoopWindowTarget`.
+- On X11, add function `register_xlib_error_hook` into `winit::platform::unix` to subscribe for errors coming from Xlib.
+- On Android, upgrade `ndk` and `ndk-glue` dependencies to the recently released `0.7.0`.
+- All platforms can now be relied on to emit a `Resumed` event. Applications are recommended to lazily initialize graphics state and windows on first resume for portability.
+- **Breaking:**: Reverse horizontal scrolling sign in `MouseScrollDelta` to match the direction of vertical scrolling. A positive X value now means moving the content to the right. The meaning of vertical scrolling stays the same: a positive Y value means moving the content down.
+- On MacOS, fix deadlock when calling `set_maximized` from event loop.
