-# 0.27.3 (2022-9-10)
+- On X11, fix swapped instance and general class names.
+- **Breaking:** Removed unnecessary generic parameter `T` from `EventLoopWindowTarget`.
+- On Windows, macOS, X11, Wayland and Web, implement setting images as cursors. See the `custom_cursors.rs` example.
+  - **Breaking:** Remove `Window::set_cursor_icon`
+  - Add `WindowBuilder::with_cursor` and `Window::set_cursor` which takes a `CursorIcon` or `CustomCursor`
+  - Add `CustomCursor`
+  - Add `CustomCursor::from_rgba` to allow creating cursor images from RGBA data.
+  - Add `CustomCursorExtWebSys::from_url` to allow loading cursor images from URLs.
+  - Add `CustomCursorExtWebSys::from_animation` to allow creating animated cursors from other `CustomCursor`s.
+- On macOS, add services menu.
+- **Breaking:** On Web, remove queuing fullscreen request in absence of transient activation.
+- On Web, fix setting cursor icon overriding cursor visibility.
+- **Breaking:** On Web, return `RawWindowHandle::WebCanvas` instead of `RawWindowHandle::Web`.
+- **Breaking:** On Web, macOS and iOS, return `HandleError::Unavailable` when a window handle is not available.
+- **Breaking:** Bump MSRV from `1.65` to `1.70`.
+- On Web, add the ability to toggle calling `Event.preventDefault()` on `Window`.
+- **Breaking:** Remove `WindowAttributes::fullscreen()` and expose as field directly.
+- **Breaking:** Rename `VideoMode` to `VideoModeHandle` to represent that it doesn't hold static data.
+- **Breaking:** No longer export `platform::x11::XNotSupported`.
+- **Breaking:** Renamed `platform::x11::XWindowType` to `platform::x11::WindowType`.
+- Add the `OwnedDisplayHandle` type for allowing safe display handle usage outside of trivial cases.
+- **Breaking:** Rename `TouchpadMagnify` to `PinchGesture`, `SmartMagnify` to `DoubleTapGesture` and `TouchpadRotate` to `RotationGesture` to represent the action rather than the intent.
+- on iOS, add detection support for `PinchGesture`, `DoubleTapGesture` and `RotationGesture`.
+- on Windows: add `with_system_backdrop`, `with_border_color`, `with_title_background_color`, `with_title_text_color` and `with_corner_preference`

-## Making a new release
+## Release process
 
-If you believe a new release is warranted, you can make a pull-request with:
-- An updated version number (remember to change the version everywhere it is used).
-- A new section in the changelog (below the `# Unreleased` section).
+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.
 
-This gives contributors an opportunity to squeeze in an extra PR or two that they feel is valuable
-enough to warrant blocking the release a little.
+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.
 
-Once the PR is merged, a maintainer will create a new tag matching the version name (e.g. `v0.26.1`),
-and a CI job will automatically release the new version. Remember that the release date in the
-changelog must be kept in check with the actual release date.
+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
+  
+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

 ## 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 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,
-};
-
-fn main() {
-    let event_loop = EventLoop::new();
-    let window = WindowBuilder::new().build(&event_loop).unwrap();
-
-    event_loop.run(move |event, _, control_flow| {
-        *control_flow = ControlFlow::Wait;
-
-        match event {
-            Event::WindowEvent {
-                event: WindowEvent::CloseRequested,
-                window_id,
-            } if window_id == window.id() => *control_flow = ControlFlow::Exit,

+## MSRV Policy
+
+This crate's Minimum Supported Rust Version (MSRV) is **1.70**. Changes to
+the MSRV will be accompanied by a minor version bump.
+
+As a **tentative** policy, the upper bound of the MSRV is given by the following
+formula:
+
+```
+min(sid, stable - 3)
+```
+
+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.
+
+[Debian Sid]: https://packages.debian.org/sid/rustc
+
+The exception is 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.
+
+All crates in the [`rust-windowing`] organizations have the
+same MSRV policy.

 #### 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 Android backend builds on (and exposes types from) the [`ndk`](https://docs.rs/ndk/latest/ndk/) crate.
 
-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.
+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` compatibility table with `ndk-glue`:
+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)).
 
-| winit |       ndk-glue       |
-| :---: | :------------------: |
-| 0.24  | `ndk-glue = "0.2.0"` |
-| 0.25  | `ndk-glue = "0.3.0"` |
-| 0.26  | `ndk-glue = "0.5.0"` |
-| 0.27  | `ndk-glue = "0.7.0"` |
+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.
 
-Running on an Android device needs a dynamic system library, add this to Cargo.toml:
+`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"`           |

+| 0.24  | `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
-[[example]]
-name = "request_redraw_threaded"
+[lib]
+name = "main"
 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() {
-    ...
-}
-```
+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:
 
-And run the application with `cargo apk run --example request_redraw_threaded`

+
+##### 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).
