+  - Rename `http::header::Accept::{mime_preference => preference}()`. [#2480]
+  - Rename `middleware::DefaultHeaders::{content_type => add_content_type}()`. [#1875]
+  - Rename `dev::ConnectionInfo::{remote_addr => peer_addr}`, deprecating the old name. [#2554]
+- Trait Implementations:
+  - `HttpResponse` can now be used as a `Responder` with any body type. [#2567]
+- Misc:
+  - Maximum number of handler extractors has increased to 12. [#2582]

+  - Minimum supported Rust version (MSRV) is now 1.54.
+
+### Fixed
+- Auto-negotiation of content encoding is more fault-tolerant when using the `Compress` middleware. [#2501]
+- Scope and Resource middleware can access data items set on their own layer. [#2288]
+- Multiple calls to `App::data()` with the same type now keeps the latest call's data. [#1906]
+- Typed headers containing lists that require one or more items now enforce this minimum. [#2482]
+- `dev::ConnectionInfo::peer_addr` will no longer return the port number. [#2554]
+- `dev::ConnectionInfo::realip_remote_addr` will no longer return the port number if sourcing the IP from the peer's socket address. [#2554]
+- Accept wildcard `*` items in `AcceptLanguage`. [#2480]
+- Relax `Unpin` bound on `S` (stream) parameter of `HttpResponseBuilder::streaming`. [#2448]
+- Fix quality parse error in `http::header::AcceptEncoding` typed header. [#2344]
+- Double ampersand in `middleware::Logger` format is escaped correctly. [#2067]
+- Added the underlying parse error to `test::read_body_json`'s panic message. [#1812]
+
+### Security
+- `cookie` upgrade addresses [`RUSTSEC-2020-0071`].

 ### `BoxBody`
 
-`BoxBody` is a new type-erased body type. It's used for all error response bodies.  
-Creating a boxed body is best done by calling [`.boxed()`](https://docs.rs/actix-web/4/actix_web/body/trait.MessageBody.html#method.boxed) on a `MessageBody` type.
+`BoxBody` is a new type-erased body type.
+
+It can be useful when writing handlers, responders, and middleware when you want to trade a (very) small amount of performance for a simpler type.
+
+Creating a boxed body is done most efficiently by calling [`.boxed()`](https://docs.rs/actix-web/4/actix_web/body/trait.MessageBody.html#method.boxed) on a `MessageBody` type.
 
 ### `EitherBody`
 
-`EitherBody` is a new "either" type that is particularly useful in middlewares that can bail early, returning their own response plus body type.
+`EitherBody` is a new "either" type that implements `MessageBody`
+
+It is particularly useful in middleware that can bail early, returning their own response plus body type. By default the "right" variant is `BoxBody` (i.e., `EitherBody<B>` === `EitherBody<B, BoxBody>`) but it can be anything that implements `MessageBody`.
+
+For example, it will be common among middleware which value performance of the hot path to use:
+
+```rust
+type Response = Result<ServiceResponse<EitherBody<B>>, Error>
+```
+
+This can be read (ignoring the `Result`) as "resolves with a `ServiceResponse` that is either the inner service's `B` body type or a boxed body type from elsewhere, likely constructed within the middleware itself". Of course, if your middleware contains only simple string other/error responses, it's possible to use them without boxes at the cost of a less simple implementation:
+
+```rust
+type Response = Result<ServiceResponse<EitherBody<B, String>>, Error>
+```
 
 ### Error Handlers
 
-TODO In particular, folks seem to be struggling with the `ErrorHandlers` middleware because of this change and the obscured nature of `EitherBody` within its types.
+`ErrorHandlers` is a commonly used middleware that has changed in design slightly due to the other body type changes.
+
+In particular, an implicit `EitherBody` is used in the `ErrorHandlerResponse<B>` type. An `ErrorHandlerResponse<B>` now expects a `ServiceResponse<EitherBody<B>>` to be returned within response variants. The following is a migration for an error handler that **only modifies** the response argument (left body).
+
+```diff
+  fn add_error_header<B>(mut res: ServiceResponse<B>) -> Result<ErrorHandlerResponse<B>, Error> {
+      res.response_mut().headers_mut().insert(
+          header::CONTENT_TYPE,
+          header::HeaderValue::from_static("Error"),
+      );
+-     Ok(ErrorHandlerResponse::Response(res))
++     Ok(ErrorHandlerResponse::Response(res.map_into_left_body()))
+  }
+```
+
+The following is a migration for an error handler that creates a new response instead (right body).
+
+```diff
+  fn error_handler<B>(res: ServiceResponse<B>) -> Result<ErrorHandlerResponse<B>, Error> {
+-     let req = res.request().clone();
++     let (req, _res) = res.into_parts();
+
+      let res = actix_files::NamedFile::open("./templates/404.html")?
+          .set_status_code(StatusCode::NOT_FOUND)
+-         .into_response(&req)?
+-         .into_body();
++         .into_response(&req);
+
+-     let res = ServiceResponse::new(req, res);
++     let res = ServiceResponse::new(req, res).map_into_right_body();
+      Ok(ErrorHandlerResponse::Response(res))
+  }
+```
 
 ## Middleware Trait APIs
 
-This section builds upon guidance from the [response body types](#response-body-types) section.
+The underlying traits that are used for creating middleware, `Service`, `ServiceFactory`, and `Transform`, have changed in design.
 
-TODO
+- The associated `Request` type has moved to the type parameter position in order to allow multiple request implementations in other areas of the service stack.
+- The `self` arguments in `Service` have changed from exclusive (mutable) borrows to shared (immutable) borrows. Since most service layers, such as middleware, do not host mutable state, it reduces the runtime overhead in places where a `RefCell` used to be required for wrapping an inner service.
+- We've also introduced some macros that reduce boilerplate when implementing `poll_ready`.
+- Further to the guidance on [response body types](#response-body-types), any use of the old methods on `ServiceResponse` designed to match up body types (e.g., the old `into_body` method), should be replaced with an explicit response body type utilizing `EitherBody<B>`.
 
-TODO: Also write the Middleware author's guide.
+A typical migration would look like this:
+
+```diff
+  use std::{
+-     cell::RefCell,
+      future::Future,
+      pin::Pin,
+      rc::Rc,
+-     task::{Context, Poll},
+  };
+
+  use actix_web::{
+      dev::{Service, ServiceRequest, ServiceResponse, Transform},

+  };

+
+  pub struct SayHi;
+
+- impl<S, B> Transform<S> for SayHi
++ impl<S, B> Transform<S, ServiceRequest> for SayHi

+          })
+      }

+-     service: Rc<RefCell<S>>,
++     service: Rc<S>,
+  }
+
+- impl<S, B> Service for SayHiMiddleware<S>
++ impl<S, B> Service<ServiceRequest> for SayHiMiddleware<S>
+  where
+-     S: Service<Request = ServiceRequest, Response = ServiceResponse<B>, Error = Error>,
++     S: Service<ServiceRequest, Response = ServiceResponse<B>, Error = Error>,
+      S::Future: 'static,
+      B: 'static,
+  {
+-     type Request = ServiceRequest;
+      type Response = ServiceResponse<B>;
+      type Error = Error;
+      type Future = LocalBoxFuture<'static, Result<Self::Response, Self::Error>>;
+
+-     fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>> {
+-         self.service.poll_ready(cx)
+-     }
++     actix_web::dev::forward_ready!(service);
+
+-     fn call(&mut self, req: ServiceRequest) -> Self::Future {
++     fn call(&self, req: ServiceRequest) -> Self::Future {
+          println!("Hi from start. You requested: {}", req.path());
+
+          let fut = self.service.call(req);
+
+          Box::pin(async move {
+              let res = fut.await?;
+
+              println!("Hi from response");
+              Ok(res)
+          })
+      }
+  }
+```
+
+This new design is forward-looking and should ease transition to traits that support the upcoming Generic Associated Type (GAT) feature in Rust while also trimming down the boilerplate required to implement middleware.
+
+We understand that creating middleware is still a pain point for Actix Web and we hope to provide [an even more ergonomic solution](https://docs.rs/actix-web-lab/0.11.0/actix_web_lab/middleware/fn.from_fn.html) in a v4.x release.

+/// built-in implementations:
+/// - `HttpResponse` and `HttpResponseBuilder`
+/// - `Option<R>` where `R: Responder`
+/// - `Result<R, E>` where `R: Responder` and [`E: ResponseError`](crate::ResponseError)
+/// - `(R, StatusCode) where `R: Responder`
+/// - `&'static str`, `String`, `&'_ String`, `Cow<'_, str>`, [`ByteString`](bytestring::ByteString)
+/// - `&'static [u8]`, `Vec<u8>`, `Bytes`, `BytesMut`
+/// - [`Json<T>`](crate::web::Json) and [`Form<T>`](crate::web::Form) where `T: Serialize`
+/// - [`Either<L, R>`](crate::web::Either) where `L: Serialize` and `R: Serialize`
+/// - [`CustomizeResponder<R>`]
+/// - [`actix_files::NamedFile`](https://docs.rs/actix-files/latest/actix_files/struct.NamedFile.html)
+/// - [Experimental responders from `actix-web-lab`](https://docs.rs/actix-web-lab/latest/actix_web_lab/respond/index.html)
+/// - Third party integrations may also have implemented `Responder` where appropriate. For example,
+///   HTML templating engines.
+///
+/// # Customizing Responder Output
+/// Calling [`.customize()`](Responder::customize) on any responder type will wrap it in a
