 ## Unreleased - 2021-xx-xx
 
 
+## 4.0.0-beta.14 - 2021-12-11
+### Added
+* Methods on `AcceptLanguage`: `ranked` and `preference`. [#2480]
+* `AcceptEncoding` typed header. [#2482]
+* `Range` typed header. [#2485]
+* `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]
+* Connection data set through the `HttpServer::on_connect` callback is now accessible only from the new `HttpRequest::conn_data()` and `ServiceRequest::conn_data()` methods. [#2491]
+* `HttpRequest::{req_data,req_data_mut}`. [#2487]
+* `ServiceResponse::into_parts`. [#2499]
+
+### Changed
+* 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]
+* Remove `B` (body) type parameter on `App`. [#2493]
+* Add `B` (body) type parameter on `Scope`. [#2492]
+* Request-local data container is no longer part of a `RequestHead`. Instead it is a distinct part of a `Request`. [#2487]
+
+### 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]
+
+### Removed
+* `ConnectionInfo::get`. [#2487]

+* `header::QualityItem::{max, min}`. [#2486]
+* `header::Quality::{MAX, MIN}`. [#2486]
+* `impl Display` for `header::Quality`. [#2486]
+* Connection data set through the `on_connect_ext` callbacks is now accessible only from the new `Request::conn_data()` method. [#2491]
+* `Request::take_conn_data()`. [#2491]
+* `Request::take_req_data()`. [#2487]
+* `impl Clone` for `RequestHead`. [#2487]
+* New methods on `MessageBody` trait, `is_complete_body` and `take_complete_body`, both with default implementations, for optimisations on body types that are done in exactly one poll/chunk. [#2497]
+
+### 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]

+
+### 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]
+* `impl Copy` for `ws::Codec`. [#1920]
+* `header::qitem` helper. Replaced with `header::QualityItem::max`. [#2486]
+* `impl TryFrom<u16>` for `header::Quality`. [#2486]
