-# 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 a 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
 
-- your patch builds with Winit's minimal supported rust version - Rust 1.70.
-- 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.
+During the review process certain events could require an action from your side,
+common patterns and reactions are described below.
 
-  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.
+_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.
 
-Once your PR is open, you can ask for a 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:_ 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.
 
-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.
+_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.

-The current maintainers are listed in the [CODEOWNERS](.github/CODEOWNERS) file.
+## Maintainers
 
-If you are interested in being pinged when testing is needed for a specific platform, please add yourself to the [Testers and Contributors](https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors) table!
+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.
 
-## Release process
+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.
+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. 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
-  
+  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

-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 the example code using Winit on Web, check out the [web example]. For
-information on using Rust on WebAssembly, check out the [Rust and WebAssembly
-book].

-
-#### Android
-
-The Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/latest/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 entry point. If Cargo resolves multiple versions, they will
-clash.
-
-`winit` glue compatibility table:
-
-| winit |       ndk-glue               |
-| :---: | :--------------------------: |
-| 0.29  | `android-activity = "0.5"`   |
-| 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`], 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`]) |

-
-##### 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 = "0.29.10", 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::Resumed`.
-
-#### iOS
-
-Similar to macOS, iOS's main `UIApplicationMain` does some init work that's required
-by all UI-related code (see issue [#1705]). It would be best to consider creating your windows
-inside `Event::Resumed`.

-//! ### Events
+//! ## Cargo Features
 //!
-//! 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 allows you 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, its scale factor
-//! can be found by calling [`window.scale_factor()`].
+//! This crate provides the following Cargo features:
 //!
-//! ## How is the scale factor calculated?
-//!
-//! The 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 macOS versions allow the user to change the scaling factor for specific
-//!   displays. When 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:** The scale factor is suggested by the compositor for each window individually. The
-//!   monitor scale factor may differ from the window scale factor.
-//! - **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`.
+//! * `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde).
+//! * `mint`: Enables mint (math interoperability standard types) conversions.

-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

+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.

+- 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.

+## 0.11.3
+
+- 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
+
+## 0.11.2
+
+- 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.
+
+## 0.11.1
+
+- 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
+
+## 0.11.0
+
+- 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.

+## 0.12.0
+
+- 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.

+## 0.13.1
+
+- Ensure necessary `x11-dl` version is used.
+
+## 0.13.0
+
+- 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`.

+## 0.14.0
+
+- 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.

+- 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.
+
+## 0.15.0
+
+- `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`.

+- 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 `?`.

+- `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.

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.

+  - `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.

+- 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 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.
