 ## Unreleased - 2021-xx-xx
 
 
-## 4.0.0-beta.2 - 2021-xx-xx
+## 4.0.0-beta.5 - 2021-04-02
+### Added
+* `Header` extractor for extracting common HTTP headers in handlers. [#2094]
+* Added `TestServer::client_headers` method. [#2097]
+
+### 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.
+  [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]

+## 4.0.0-beta.4 - 2021-03-09
+### 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]

+
+
+## 4.0.0-beta.2 - 2021-02-10

 * The method `Either<web::Json<T>, web::Form<T>>::into_inner()` which returns the inner type for
   whichever variant was created. Also works for `Either<web::Form<T>, web::Json<T>>`. [#1894]
