### Added
* Methods on `AcceptLanguage`: `ranked` and `preference`. [#2480]
* `AcceptEncoding` typed header. [#2482]
* `HttpResponse::map_into_{left,right}_body` and `HttpResponse::map_into_boxed_body`. [#2468]
* `ServiceResponse::map_into_{left,right}_body` and `HttpResponse::map_into_boxed_body`. [#2468]
### Changed
* Rename `Accept::{mime_precedence => ranked}`. [#2480]
@ -11,8 +13,10 @@
### 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]

### Added
* Add timeout for canceling HTTP/2 server side connection handshake. Default to 5 seconds. [#2483]
* HTTP/2 handshake timeout can be configured with `ServiceConfig::client_timeout`. [#2483]
* `Response::map_into_boxed_body`. [#2468]
* `body::EitherBody` enum. [#2468]
* `body::None` struct. [#2468]
* Impl `MessageBody` for `bytestring::ByteString`. [#2468]
* `impl Clone for ws::HandshakeError`. [#2468]
### Changed
* Rename `body::BoxBody::{from_body => new}`. [#2468]
* Body type for `Responses` returned from `Response::{new, ok, etc...}` is now `BoxBody`. [#2468]
* The `Error` associated type on `MessageBody` type now requires `impl Error` (or similar). [#2468]
* Error types using in service builders now require `Into<Response<BoxBody>>`. [#2468]
* `From` implementations on error types now return a `Response<BoxBody>`. [#2468]
* `ResponseBuilder::body(B)` now returns `Response<EitherBody<B>>`. [#2468]
* `ResponseBuilder::finish()` now returns `Response<EitherBody<()>>`. [#2468]
### Removed
* `ResponseBuilder::streaming`. [#2468]
* `impl Future` for `ResponseBuilder`. [#2468]
* Remove unnecessary `MessageBody` bound on types passed to `body::AnyBody::new`. [#2468]
* Move `body::AnyBody` to `awc`. Replaced with `EitherBody` and `BoxBody`. [#2468]
[#2483]: https://github.com/actix/actix-web/pull/2483
