 ## Unreleased - 2021-xx-xx


+## 4.0.0-beta.19 - 2022-01-04
+### Added
+- `impl Hash` for `http::header::Encoding`. [#2501]
+- `AcceptEncoding::negotiate()`. [#2501]
+
+### Changed
+- `AcceptEncoding::preference` now returns `Option<Preference<Encoding>>`. [#2501]
+- Rename methods `BodyEncoding::{encoding => encode_with, get_encoding => preferred_encoding}`. [#2501]
+- `http::header::Encoding` now only represents `Content-Encoding` types. [#2501]
+
+### Fixed
+- Auto-negotiation of content encoding is more fault-tolerant when using the `Compress` middleware. [#2501]
+
+### Removed
+- `Compress::new`; restricting compression algorithm is done through feature flags. [#2501]
+- `BodyEncoding` trait; signalling content encoding is now only done via the `Content-Encoding` header. [#2565]
+
+[#2501]: https://github.com/actix/actix-web/pull/2501
+[#2565]: https://github.com/actix/actix-web/pull/2565
+
+
+## 4.0.0-beta.18 - 2021-12-29
+### Changed
+- Update `cookie` dependency (re-exported) to `0.16`. [#2555]
+- Minimum supported Rust version (MSRV) is now 1.54.
+
+### Security
+- `cookie` upgrade addresses [`RUSTSEC-2020-0071`].
+
+[#2555]: https://github.com/actix/actix-web/pull/2555
+[`RUSTSEC-2020-0071`]: https://rustsec.org/advisories/RUSTSEC-2020-0071.html
+
+
 ## 4.0.0-beta.17 - 2021-12-29
 ### Added
 - `guard::GuardContext` for use with the `Guard` trait. [#2552]

+### Added
+- `impl Eq` for `header::ContentEncoding`. [#2501]
+- `impl Copy` for `QualityItem` where `T: Copy`. [#2501]
+- `Quality::ZERO` equivalent to `q=0`. [#2501]
+- `QualityItem::zero` that uses `Quality::ZERO`. [#2501]
+- `ContentEncoding::to_header_value()`. [#2501]
+
+### Changed
+- `Quality::MIN` is now the smallest non-zero value. [#2501]
+- `QualityItem::min` semantics changed with `QualityItem::MIN`. [#2501]
+- Rename `ContentEncoding::{Br => Brotli}`. [#2501]
+- Minimum supported Rust version (MSRV) is now 1.54.
+- Rename `header::EntityTag::{weak => new_weak, strong => new_strong}`. [#2565]

-/// Application data.
+/// Application data wrapper and extractor.
 ///
-/// Application level data is a piece of arbitrary data attached to the app, scope, or resource.
-/// Application data is available to all routes and can be added during the application
-/// configuration process via `App::data()`.
+/// # Setting Data
+/// Data is set using the `app_data` methods on `App`, `Scope`, and `Resource`. If data is wrapped
+/// in this `Data` type for those calls, it can be used as an extractor.
 ///
-/// Application data can be accessed by using `Data<T>` extractor where `T` is data type.
+/// Note that `Data` should be constructed _outside_ the `HttpServer::new` closure if shared,
+/// potentially mutable state is desired. `Data` is cheap to clone; internally, it uses an `Arc`.
 ///
-/// **Note**: HTTP server accepts an application factory rather than an application instance. HTTP
-/// server constructs an application instance for each thread, thus application data must be
-/// constructed multiple times. If you want to share data between different threads, a shareable
-/// object should be used, e.g. `Send + Sync`. Application data does not need to be `Send`
-/// or `Sync`. Internally `Data` contains an `Arc`.
+/// See also [`App::app_data`](crate::App::app_data), [`Scope::app_data`](crate::Scope::app_data),
+/// and [`Resource::app_data`](crate::Resource::app_data).
+///
+/// # Extracting `Data`
+/// Since the Actix Web router layers application data, the returned object will reference the
+/// "closest" instance of the type. For example, if an `App` stores a `u32`, a nested `Scope`
+/// also stores a `u32`, and the delegated request handler falls within that `Scope`, then
+/// extracting a `web::<Data<u32>>` for that handler will return the `Scope`'s instance.
+/// However, using the same router set up and a request that does not get captured by the `Scope`,
+/// `web::<Data<u32>>` would return the `App`'s instance.
 ///
 /// If route data is not set for a handler, using `Data<T>` extractor would cause a `500 Internal
 /// Server Error` response.
 ///
+/// See also [`HttpRequest::app_data`]
+/// and [`ServiceRequest::app_data`](crate::dev::ServiceRequest::app_data).

 /// Middleware for compressing response payloads.
 ///
-/// Use `BodyEncoding` trait for overriding response compression. To disable compression set
-/// encoding to `ContentEncoding::Identity`.
+/// # Encoding Negotiation
+/// `Compress` will read the `Accept-Encoding` header to negotiate which compression codec to use.
+/// Payloads are not compressed if the header is not sent. The `compress-*` [feature flags] are also
+/// considered in this selection process.
+///
+/// # Pre-compressed Payload
+/// If you are serving some data is already using a compressed representation (e.g., a gzip
+/// compressed HTML file from disk) you can signal this to `Compress` by setting an appropriate
+/// `Content-Encoding` header. In addition to preventing double compressing the payload, this header
+/// is required by the spec when using compressed representations and will inform the client that
+/// the content should be uncompressed.
+///
+/// However, it is not advised to unconditionally serve encoded representations of content because
+/// the client may not support it. The [`AcceptEncoding`] typed header has some utilities to help
+/// perform manual encoding negotiation, if required. When negotiating content encoding, it is also
+/// required by the spec to send a `Vary: Accept-Encoding` header.
+///
+/// A (naïve) example serving an pre-compressed Gzip file is included below.
 ///
 /// # Examples

 /// ```
