+* Rename `test::{default_service => simple_service}`. Old name is deprecated. [#2518]
+* Rename `test::{read_response_json => call_and_read_body_json}`. Old name is deprecated. [#2518]
+* Rename `test::{read_response => call_and_read_body}`. Old name is deprecated. [#2518]
+* Relax body type and error bounds on test utilities.
+
+### Removed
+* Top-level `EitherExtractError` export. [#2510]
+* Conversion implementations for `either` crate. [#2516]

+
+## 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]
