Release 0.26.1 (#2125)

The repository is configured such that specific checks are required to pass before merging; since CI doesn't run on PRs that don't change code, they can't be merged without administrator intervention.

Also, while this definition is currently correct, we might in the future change something so that changes to other files (like markdown files) really should be run through CI.

And example of that could be:
```rust
#[cfg(doctest)]
#[doc = include_str!("../README.md")]
extern "C" {}
```

-# Unreleased
+# 0.26.1 (2022-01-05)
+
+- Fix linking to the `ColorSync` framework on macOS 10.7, and in newer Rust versions.
+- On Web, implement cursor grabbing through the pointer lock API.
+- On X11, add mappings for numpad comma, numpad enter, numlock and pause.
+- On macOS, fix Pinyin IME input by reverting a change that intended to improve IME.
+- On Windows, fix a crash with transparent windows on Windows 11.
+
+# 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 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 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.

 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.
 
 ### Platform-specific usage
 
 #### WebAssembly
 
-Building a binary will yield a `.js` file. In order to use it in an HTML file, you need to:
+Winit supports compiling to the `wasm32-unknown-unknown` target with `web-sys`.
 
-- Put a `<canvas id="my_id"></canvas>` element somewhere. A canvas corresponds to a winit "window".
-- Write a Javascript code that creates a global variable named `Module`. Set `Module.canvas` to
-  the element of the `<canvas>` element (in the example you would retrieve it via `document.getElementById("my_id")`).
-  More information [here](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
-- Make sure that you insert the `.js` file generated by Rust after the `Module` variable is created.
+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       |
+| :---: | :------------------: |

+| 0.25  | `ndk_glue = "0.3.0"` |

 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.
