+                 Reason:
+                 AsyncRead mostly would only have guarantee wake up
+                 when the poll_read return Poll::Pending.
+
+                 Case:
+                 When read_buf is beyond max buffer size the early return
+                 could be successfully be parsed as a new Request.
+                 This case would not generate ParseError::TooLarge
+                 and at this point IO stream is not fully read to Pending
+                 and would result in dispatcher stuck until timeout (KA)
+
+                 Note:
+                 This is a perf choice to reduce branch on
+                 <Request as MessageType>::decode.
+
+                 A Request head too large to parse is only checked on
+                 httparse::Status::Partial condition.

+
+                    Reason:
+                    Self wake up when there is payload would waste poll
+                    and/or result in over read.
+
+                    Case:
+                    When payload is (partial) dropped by user there is
+                    no need to do read anymore.
+                    At this case read_buf could always remain beyond
+                    MAX_BUFFER_SIZE and self wake up would be busy poll

 ### Changed
 * Feature `cookies` is now optional and enabled by default. [#1981]
+* `JsonBody::new` returns a default limit of 32kB to be consistent with `JsonConfig` and the
+  default behaviour of the `web::Json<T>` extractor. [#2010]

 ### Fixed
 * Double ampersand in Logger format is escaped correctly. [#2067]
 
+### Changed
+* `CustomResponder` would return error as `HttpResponse` when `CustomResponder::with_header` failed instead of skipping.
+  (Only the first error is kept when multiple error occur) [#2093]
+
 ### Removed
 * The `client` mod was removed. Clients should now use `awc` directly.

 * `ConnectorService` type is renamed to `BoxConnectorService`. [#2081]
 * Fix http/https encoding when enabling `compress` feature. [#2116]
+* Rename `TestResponse::header` to `append_header`, `set` to `insert_header`. `TestResponse` header methods now take `IntoHeaderPair` tuples. [#2094]

 ### Removed
 * The `client` mod was removed. Clients should now use `awc` directly.
   [871ca5e4](https://github.com/actix/actix-web/commit/871ca5e4ae2bdc22d1ea02701c2992fa8d04aed7)
+* Integration testing was moved to new `actix-test` crate. Namely these items from the `test`
+  module: `TestServer`, `TestServerConfig`, `start`, `start_with`, and `unused_addr`. [#2112]

+//! Integration testing tools for Actix Web applications.
+//!
+//! The main integration testing tool is [`TestServer`]. It spawns a real HTTP server on an
+//! unused port and provides methods that use a real HTTP client. Therefore, it is much closer to
+//! real-world cases than using `init_service`, which skips HTTP encoding and decoding.
+//!
+//! # Examples
+//! ```
+//! use actix_web::{get, web, test, App, HttpResponse, Error, Responder};
+//!
+//! #[get("/")]
+//! async fn my_handler() -> Result<impl Responder, Error> {
+//!     Ok(HttpResponse::Ok())
+//! }
+//!
+//! #[actix_rt::test]
+//! async fn test_example() {
+//!     let srv = actix_test::start(||
+//!         App::new().service(my_handler)
+//!     );
+//!
+//!     let req = srv.get("/");
+//!     let res = req.send().await.unwrap();
+//!
+//!     assert!(res.status().is_success());
+//! }
+//! ```

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### Added
+* `impl<T: MessageBody> MessageBody for Pin<Box<T>>`. [#2152]
+
+### Changes
+* The type parameter of `Response` no longer has a default. [#2152]
+* The `Message` variant of `body::Body` is now `Pin<Box<dyn MessageBody>>`. [#2152]
+* `BodyStream` and `SizedStream` are no longer restricted to Unpin types. [#2152]
+
 ### Removed
 * `cookies` feature flag. [#2065]
 * Top-level `cookies` mod (re-export). [#2065]

 ## Unreleased - 2021-xx-xx
+* `NamedFile` now implements `ServiceFactory` and `HttpServiceFactory` making it much more useful in routing. For example, it can be used directly as a default service. [#2135]
 * For symbolic links, `Content-Disposition` header no longer shows the filename of the original file. [#2156]

 ## Unreleased - 2021-xx-xx
 * `NamedFile` now implements `ServiceFactory` and `HttpServiceFactory` making it much more useful in routing. For example, it can be used directly as a default service. [#2135]
 * For symbolic links, `Content-Disposition` header no longer shows the filename of the original file. [#2156]
+* `Files::redirect_to_slash_directory()` now works as expected when used with `Files::show_files_listing()`. [#2225]

 * `NamedFile` now implements `ServiceFactory` and `HttpServiceFactory` making it much more useful in routing. For example, it can be used directly as a default service. [#2135]
 * For symbolic links, `Content-Disposition` header no longer shows the filename of the original file. [#2156]
 * `Files::redirect_to_slash_directory()` now works as expected when used with `Files::show_files_listing()`. [#2225]

 # Changes
 
 ## Unreleased - 2021-xx-xx
+
+
+## 0.6.0-beta.5 - 2021-06-17
 * `NamedFile` now implements `ServiceFactory` and `HttpServiceFactory` making it much more useful in routing. For example, it can be used directly as a default service. [#2135]
 * For symbolic links, `Content-Disposition` header no longer shows the filename of the original file. [#2156]
 * `Files::redirect_to_slash_directory()` now works as expected when used with `Files::show_files_listing()`. [#2225]

   Alternatively, explicitly require trailing slashes: `NormalizePath::new(TrailingSlash::Always)`.
 
+* Feature flag `compress` has been split into its supported algorithm (brotli, gzip, zstd).
+  By default all compression algorithms are enabled.
+  To select algorithm you want to include with `middleware::Compress` use following flags:
+  - `compress-brotli`
+  - `compress-gzip`
+  - `compress-zstd`
+  If you have set in your `Cargo.toml` dedicated `actix-web` features and you still want
+  to have compression enabled. Please change features selection like bellow:
+
+  Before: `"compress"`
+  After: `"compress-brotli", "compress-gzip", "compress-zstd"`

+## 0.4.0 - 2021-06-06
+* When matching path parameters, `%25` is now kept in the percent-encoded form; no longer decoded to `%`. [#357]
+* Path tail patterns now match new lines (`\n`) in request URL. [#360]
+* Fixed a safety bug where `Path` could return a malformed string after percent decoding. [#359]

+/// Regex flags to allow '.' in regex to match '\n'
+///
+/// See the docs under: https://docs.rs/regex/1/regex/#grouping-and-flags
+const REGEX_FLAGS: &str = "(?s-m)";
+
+/// Describes the set of paths that match to a resource.
+///
+/// `ResourceDef`s are effectively a way to transform the a custom resource pattern syntax into
+/// suitable regular expressions from which to check matches with paths and capture portions of a
+/// matched path into variables. Common cases are on a fast path that avoids going through the
+/// regex engine.
+///
+///
+/// # Static Resources
+/// A static resource is the most basic type of definition. Pass a regular string to
+/// [new][Self::new]. Conforming paths must match the string exactly.
+///
+/// ## Examples
+/// ```
+/// # use actix_router::ResourceDef;
+/// let resource = ResourceDef::new("/home");
+///
+/// assert!(resource.is_match("/home"));
+///
+/// assert!(!resource.is_match("/home/new"));
+/// assert!(!resource.is_match("/homes"));
+/// assert!(!resource.is_match("/search"));
+/// ```
+///
+///
+/// # Dynamic Segments
+/// Also known as "path parameters". Resources can define sections of a pattern that be extracted
+/// from a conforming path, if it conforms to (one of) the resource pattern(s).
+///
+/// The marker for a dynamic segment is curly braces wrapping an identifier. For example,
+/// `/user/{id}` would match paths like `/user/123` or `/user/james` and be able to extract the user
+/// IDs "123" and "james", respectively.
+///
+/// However, this resource pattern (`/user/{id}`) would, not cover `/user/123/stars` (unless
+/// constructed as a prefix; see next section) since the default pattern for segments matches all
+/// characters until it finds a `/` character (or the end of the path). Custom segment patterns are
+/// covered further down.
+///
+/// Dynamic segments do not need to be delimited by `/` characters, they can be defined within a
+/// path segment. For example, `/rust-is-{opinion}` can match the paths `/rust-is-cool` and
+/// `/rust-is-hard`.
+///
+/// For information on capturing segment values from paths or other custom resource types,
+/// see [`capture_match_info`][Self::capture_match_info]
+/// and [`capture_match_info_fn`][Self::capture_match_info_fn].
+///
+/// A resource definition can contain at most 16 dynamic segments.
+///
+/// ## Examples
+/// ```
+/// use actix_router::{Path, ResourceDef};
+///
+/// let resource = ResourceDef::prefix("/user/{id}");
+///
+/// assert!(resource.is_match("/user/123"));
+/// assert!(!resource.is_match("/user"));
+/// assert!(!resource.is_match("/user/"));
+///
+/// let mut path = Path::new("/user/123");
+/// resource.capture_match_info(&mut path);
+/// assert_eq!(path.get("id").unwrap(), "123");
+/// ```
+///
+///
+/// # Prefix Resources
+/// A prefix resource is defined as pattern that can match just the start of a path.
+///
+/// This library chooses to restrict that definition slightly. In particular, when matching, the
+/// prefix must be separated from the remaining part of the path by a `/` character, either at the
+/// end of the prefix pattern or at the start of the the remaining slice. In practice, this is not
+/// much of a limitation.
+///
+/// Prefix resources can contain dynamic segments.
+///
+/// ## Examples
+/// ```
+/// # use actix_router::ResourceDef;
+/// let resource = ResourceDef::prefix("/home");
+/// assert!(resource.is_match("/home"));
+/// assert!(resource.is_match("/home/new"));
+/// assert!(!resource.is_match("/homes"));
+///
+/// let resource = ResourceDef::prefix("/user/{id}/");
+/// assert!(resource.is_match("/user/123/"));
+/// assert!(resource.is_match("/user/123/stars"));
+/// ```
+///
+///
+/// # Custom Regex Segments
+/// Dynamic segments can be customised to only match a specific regular expression. It can be
+/// helpful to do this if resource definitions would otherwise conflict and cause one to
+/// be inaccessible.
+///
+/// The regex used when capturing segment values can be specified explicitly using this syntax:
+/// `{name:regex}`. For example, `/user/{id:\d+}` will only match paths where the user ID
+/// is numeric.
+///
+/// By default, dynamic segments use this regex: `[^/]+`. This shows why it is the case, as shown in
+/// the earlier section, that segments capture a slice of the path up to the next `/` character.
+///
+/// Custom regex segments can be used in static and prefix resource definition variants.
+///
+/// ## Examples
+/// ```
+/// # use actix_router::ResourceDef;
+/// let resource = ResourceDef::new(r"/user/{id:\d+}");
+/// assert!(resource.is_match("/user/123"));
+/// assert!(resource.is_match("/user/314159"));
+/// assert!(!resource.is_match("/user/abc"));
+/// ```
+///
+///
+/// # Tail Segments
+/// As a shortcut to defining a custom regex for matching _all_ remaining characters (not just those
+/// up until a `/` character), there is a special pattern to match (and capture) the remaining
+/// path portion.
+///
+/// To do this, use the segment pattern: `{name}*`. Since a tail segment also has a name, values are
+/// extracted in the same way as non-tail dynamic segments.
+///
+/// ## Examples
+/// ```rust
+/// # use actix_router::{Path, ResourceDef};
+/// let resource = ResourceDef::new("/blob/{tail}*");
+/// assert!(resource.is_match("/blob/HEAD/Cargo.toml"));
+/// assert!(resource.is_match("/blob/HEAD/README.md"));
+///
+/// let mut path = Path::new("/blob/main/LICENSE");
+/// resource.capture_match_info(&mut path);
+/// assert_eq!(path.get("tail").unwrap(), "main/LICENSE");
+/// ```
+///
+///
+/// # Multi-Pattern Resources
+/// For resources that can map to multiple distinct paths, it may be suitable to use
+/// multi-pattern resources by passing an array/vec to [`new`][Self::new]. They will be combined
+/// into a regex set which is usually quicker to check matches on than checking each
+/// pattern individually.
+///
+/// Multi-pattern resources can contain dynamic segments just like single pattern ones.
+/// However, take care to use consistent and semantically-equivalent segment names; it could affect
+/// expectations in the router using these definitions and cause runtime panics.
+///
+/// ## Examples
+/// ```rust
+/// # use actix_router::ResourceDef;
+/// let resource = ResourceDef::new(["/home", "/index"]);
+/// assert!(resource.is_match("/home"));
+/// assert!(resource.is_match("/index"));
+/// ```
+///
+///
+/// # Trailing Slashes
+/// It should be noted that this library takes no steps to normalize intra-path or trailing slashes.
+/// As such, all resource definitions implicitly expect a pre-processing step to normalize paths if
+/// they you wish to accommodate "recoverable" path errors. Below are several examples of
+/// resource-path pairs that would not be compatible.
+///
+/// ## Examples
+/// ```rust
+/// # use actix_router::ResourceDef;
+/// assert!(!ResourceDef::new("/root").is_match("/root/"));
+/// assert!(!ResourceDef::new("/root/").is_match("/root"));
+/// assert!(!ResourceDef::prefix("/root/").is_match("/root"));
+/// ```

+/// # Pattern Format and Matching Behavior
+///
+/// Resource pattern is defined as a string of zero or more _segments_ where each segment is
+/// preceeded by a slash `/`.
+///
+/// This means that pattern string __must__ either be empty or begin with a slash (`/`).
+/// This also implies that a trailing slash in pattern defines an empty segment.
+/// For example, the pattern `"/user/"` has two segments: `["user", ""]`
+///
+/// A key point to undertand is that `ResourceDef` matches segments, not strings.
+/// It matches segments individually.
+/// For example, the pattern `/user/` is not considered a prefix for the path `/user/123/456`,
+/// because the second segment doesn't match: `["user", ""]` vs `["user", "123", "456"]`.
+///
+/// This definition is consistent with the definition of absolute URL path in
+/// [RFC 3986 (section 3.3)](https://datatracker.ietf.org/doc/html/rfc3986#section-3.3)

 /// # Static Resources
-/// A static resource is the most basic type of definition. Pass a regular string to

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### Added
+* `AnyBody::empty` for quickly creating an empty body. [#2446]
+
+### Changed
+* Rename `AnyBody::{Message => Stream}`. [#2446]
+
+### Removed
+* `AnyBody::Empty`; an empty body can now only be represented as a zero-length `Bytes` variant. [#2446]
+* `BodySize::Empty`; an empty body can now only be represented as a `Sized(0)` variant. [#2446]

 ### Added
-* `AnyBody::empty` for quickly creating an empty body. [#2446]
+* `body::AnyBody::empty` for quickly creating an empty body. [#2446]
+* `impl Clone` for `body::AnyBody<S> where S: Clone`. [#2448]
+* `body::AnyBody::into_boxed` for quickly converting to a type-erased, boxed body type. [#2448]
 
 ### Changed
-* Rename `AnyBody::{Message => Stream}`. [#2446]

 # Changes
 
 ## Unreleased - 2021-xx-xx
+* Ensure a correct Content-Disposition header is included in every part of a multipart message. [#2451]
+* Added `MultipartError::NoContentDisposition` variant. [#2451]
+* Since Content-Disposition is now ensured, `Field::content_disposition` is now infallible. [#2451]
+* Added `Field::name` method for getting the field name. [#2451]
+* `MultipartError` now marks variants with inner errors as the source. [#2451]
+* `MultipartError` is now marked as non-exhaustive. [#2451]

 # Changes
 
 ## Unreleased - 2021-xx-xx
+* Add crate feature `experimental-io-uring`, enabling async file I/O to be utilized. This feature is only available on Linux OSes with recent kernel versions. This feature is semver-exempt. [#2408]
+* Add `NamedFile::open_async`. [#2408]
 * Fix 304 Not Modified responses to omit the Content-Length header, as per the spec. [#2453]
+* The `Responder` impl for `NamedFile` now has a boxed future associated type. [#2408]
+* The `Service` impl for `NamedFileService` now has a boxed future associated type. [#2408]

 * Rename `Accept::{mime_precedence => ranked}`. [#2480]
 * Rename `Accept::{mime_preference => preference}`. [#2480]
 * Un-deprecate `App::data_factory`. [#2484]
+* `HttpRequest::url_for` no longer constructs URLs with query or fragment components. [#2430]
 
 ### Fixed
 * Accept wildcard `*` items in `AcceptLanguage`. [#2480]
 * Re-exports `dev::{BodySize, MessageBody, SizedStream}`. They are exposed through the `body` module. [#2468]
 * Typed headers containing lists that require one or more items now enforce this minimum. [#2482]

 ### Changed
 * Align `DefaultHeader` method terminology, deprecating previous methods. [#2510]
+* Response service types in `ErrorHandlers` middleware now use `ServiceResponse<EitherBody<B>>` to allow changing the body type. [#2515]
+* Both variants in `ErrorHandlerResponse` now use `ServiceResponse<EitherBody<B>>`. [#2515]
 
 ### Removed
 * Top-level `EitherExtractError` export. [#2510]

 ## Unreleased - 2021-xx-xx
 - Rename `Connector::{ssl => openssl}`. [#2503]
 - Improve `Client` instantiation efficiency when using `openssl` by only building connectors once. [#2503]
+- `ClientRequest::send_body` now takes an `impl MessageBody`. [#2546]
+- Rename `MessageBody => ResponseBody` to avoid conflicts with `MessageBody` trait. [#2546]
+- `impl Future` for `ResponseBody` no longer requires the body type be `Unpin`. [#2546]
+- `impl Future` for `JsonBody` no longer requires the body type be `Unpin`. [#2546]
+- `impl Stream` for `ClientResponse` no longer requires the body type be `Unpin`. [#2546]

-/// A request handler is an async function that accepts zero or more parameters that can be
-/// extracted from a request (i.e., [`impl FromRequest`]) and returns a type that can be converted
-/// into an [`HttpResponse`] (that is, it impls the [`Responder`] trait).
+/// The interface for request handlers.
 ///
-/// If you got the error `the trait Handler<_, _, _> is not implemented`, then your function is not
-/// a valid handler. See <https://actix.rs/docs/handlers> for more information.
+/// # What Is A Request Handler
+/// A request handler has three requirements:
+/// 1. It is an async function (or a function/closure that returns an appropriate future);
+/// 1. The function accepts zero or more parameters that implement [`FromRequest`];
+/// 1. The async function (or future) resolves to a type that can be converted into an
+///   [`HttpResponse`] (i.e., it implements the [`Responder`] trait).
 ///
-/// [`impl FromRequest`]: crate::FromRequest
+/// # Compiler Errors
+/// If you get the error `the trait Handler<_, _, _> is not implemented`, then your handler does not
+/// fulfill one or more of the above requirements.
+///
+/// Unfortunately we cannot provide a better compile error message (while keeping the trait's
+/// flexibility) unless a stable alternative to [`#[rustc_on_unimplemented]`][on_unimpl] is added
+/// to Rust.
+///
+/// # How Do Handlers Receive Variable Numbers Of Arguments
+/// Rest assured there is no macro magic here; it's just traits.
+///
+/// The first thing to note is that [`FromRequest`] is implemented for tuples (up to 12 in length).
+///
+/// Secondly, the `Handler` trait is implemented for functions (up to an [arity] of 12) in a way
+/// that aligns their parameter positions with a corresponding tuple of types (becoming the `T` type
+/// parameter in this trait's implementation).
+///
+/// Thanks to Rust's type system, Actix Web can infer the function parameter types. During the
+/// extraction step, the parameter types are described as a tuple type, [`from_request`] is run on
+/// that tuple, and the `Handler::call` implementation for that particular function arity
+/// destructures the tuple into it's component types and calls your handler function with them.
+///
+/// In pseudo-code the process looks something like this:
+/// ```ignore
+/// async fn my_handler(body: String, state: web::Data<MyState>) -> impl Responder {
+///     ...
+/// }
+///
+/// // the function params above described as a tuple, names do not matter, only position
+/// type InferredMyHandlerArgs = (String, web::Data<MyState>);
+///
+/// // create tuple of arguments to be passed to handler
+/// let args = InferredMyHandlerArgs::from_request(&request, &payload).await;
+///
+/// // call handler with argument tuple
+/// let response = Handler::call(&my_handler, args).await;
+///
+/// // which is effectively...
+///
+/// let (body, state) = args;
+/// let response = my_handler(body, state).await;
+/// ```
+///
+/// This is the source code for the 2-parameter implementation of `Handler` to help illustrate the
+/// bounds of the handler call after argument extraction:
+/// ```ignore
+/// impl<Func, Arg1, Arg2, R> Handler<(Arg1, Arg2), R> for Func
+/// where
+///     Func: Fn(Arg1, Arg2) -> R + Clone + 'static,

+- `Guard` trait now receives a `&GuardContext`. [#2552]
+- `guard::fn_guard` functions now receives a `&GuardContext`. [#2552]
+- Some guards now return `impl Guard` and their concrete types are made private: `guard::{Header}` and all the method guards. [#2552]
+- The `Not` guard is now generic over the type of guard it wraps. [#2552]

-//! Route match guards.
+//! Route guards.
 //!
-//! Guards are one of the ways how actix-web router chooses a
-//! handler service. In essence it is just a function that accepts a
-//! reference to a `RequestHead` instance and returns a boolean.
-//! It is possible to add guards to *scopes*, *resources*
-//! and *routes*. Actix provide several guards by default, like various
-//! http methods, header, etc. To become a guard, type must implement `Guard`
-//! trait. Simple functions could be guards as well.
+//! Guards are used during routing to help select a matching service or handler using some aspect of
+//! the request; though guards should not be used for path matching since it is a built-in function
+//! of the Actix Web router.
 //!
-//! Guards can not modify the request object. But it is possible
-//! to store extra attributes on a request by using the `Extensions` container.
-//! Extensions containers are available via the `RequestHead::extensions()` method.
+//! Guards can be used on [`Scope`]s, [`Resource`]s, [`Route`]s, and other custom services.
 //!
+//! Fundamentally, a guard is a predicate function that receives a reference to a request context
+//! object and returns a boolean; true if the request _should_ be handled by the guarded service
+//! or handler. This interface is defined by the [`Guard`] trait.
+//!
+//! Commonly-used guards are provided in this module as well as way of creating a guard from a
+//! closure ([`fn_guard`]). The [`Not`], [`Any`], and [`All`] guards are noteworthy, as they can be
+//! used to compose other guards in a more flexible and semantic way than calling `.guard(...)` on
+//! services multiple times (which might have different combining behavior than you want).
+//!
+//! Guards can not modify anything about the request. However, it is possible to store extra
+//! attributes in the request-local data container obtained with [`GuardContext::req_data_mut`].
+//!
+//! Guards can prevent resource definitions from overlapping (resulting in some inaccessible routes)
+//! where they otherwise would when only considering paths. See the virtual hosting example below.
+//!
+//! # Examples
+//! In the following code, the `/guarded` resource has one defined route whose handler will only be
+//! called if the request method is `POST` and there is a request header with name and value equal
+//! to `x-guarded` and `secret`, respectively.
 //! ```
-//! use actix_web::{web, http, dev, guard, App, HttpResponse};
+//! use actix_web::{web, http::Method, guard, HttpResponse};
 //!
-//! App::new().service(web::resource("/index.html").route(
+//! web::resource("/guarded").route(
 //!     web::route()
-//!          .guard(guard::Post())
-//!          .guard(guard::fn_guard(|head| head.method == http::Method::GET))
-//!          .to(|| HttpResponse::MethodNotAllowed()))
+//!         .guard(guard::Any(guard::Get()).or(guard::Post()))
+//!         .guard(guard::Header("x-guarded", "secret"))
+//!         .to(|| HttpResponse::Ok())
 //! );
 //! ```
+//!
+//! Guards can be used to set up some form of [virtual hosting] within a single app.
+//! Overlapping scope prefixes are usually discouraged, but when combined with non-overlapping guard
+//! definitions they become safe to use in this way. Without these host guards, only routes under
+//! the first-to-be-defined scope would be accessible. You can test this locally using `127.0.0.1`
+//! and `localhost` as the `Host` guards.
+//! ```
+//! use actix_web::{web, http::Method, guard, App, HttpResponse};
+//!
+//! App::new()
+//!     .service(
+//!         web::scope("")
+//!             .guard(guard::Host("www.rust-lang.org"))
+//!             .default_service(web::to(|| HttpResponse::Ok().body("marketing site"))),
+//!     )
+//!     .service(
+//!         web::scope("")
+//!             .guard(guard::Host("play.rust-lang.org"))
+//!             .default_service(web::to(|| HttpResponse::Ok().body("playground frontend"))),
+//!     );
+//! ```

 ## Unreleased - 2021-xx-xx
 ### Changed
+- `actix-web` has upgraded to `cookie` 0.16. This removes `actix-web`'s dependency on a version of `time` that was affected by RUSTSEC-2020-0071. `actix-web` still depends on a vulnerable version of `chrono` via `rcgen`, but `rcgen` is only used as a dev dependency therefore this does not affect end users.
 - Minimum supported Rust version (MSRV) is now 1.54.
 
-
 ## 4.0.0-beta.17 - 2021-12-29
 ### Added
 - `guard::GuardContext` for use with the `Guard` trait. [#2552]

+/// 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).

 /// constructing an `Arc<dyn T>` and using the `From` implementation to convert it.

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### 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]

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### 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.
 
+### Fixed
+- `ContentEncoding::Identity` can now be parsed from a string. [#2501]
+- A `Vary` header is now correctly sent along with compressed content. [#2501]
+
+### Removed
+- `ContentEncoding::Auto` variant. [#2501]
+- `ContentEncoding::is_compression()`. [#2501]

 ///
-/// 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
+/// To enable automatic payload compression just include `Compress` as a top-level middleware:
 /// ```
-/// use actix_web::{web, middleware, App, HttpResponse};
+/// use actix_web::{middleware, web, App, HttpResponse};
 ///
 /// let app = App::new()

 /// ```

+/// Pre-compressed Gzip file being served from disk with correct headers added to bypass middleware:
+/// ```no_run
