# Changes
## Unreleased - 2021-xx-xx
## 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]
[#1981]: https://github.com/actix/actix-web/pull/1981
[#2010]: https://github.com/actix/actix-web/pull/2010
## 4.0.0-beta.3 - 2021-02-10
* Update `actix-web-codegen` to `0.5.0-beta.1`.
## 4.0.0-beta.2 - 2021-02-10
### Added
* 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]
* Add `services!` macro for helping register multiple services to `App`. [#1933]
* Enable registering a vec of services of the same type to `App` [#1933]
### Changed
* Rework `Responder` trait to be sync and returns `Response`/`HttpResponse` directly.
Making it simpler and more performant. [#1891]
* `ServiceRequest::into_parts` and `ServiceRequest::from_parts` can no longer fail. [#1893]
* `ServiceRequest::from_request` can no longer fail. [#1893]
* Our `Either` type now uses `Left`/`Right` variants (instead of `A`/`B`) [#1894]
* `test::{call_service, read_response, read_response_json, send_request}` take `&Service`
in argument [#1905]
* `App::wrap_fn`, `Resource::wrap_fn` and `Scope::wrap_fn` provide `&Service` in closure
argument. [#1905]
* `web::block` no longer requires the output is a Result. [#1957]
### Fixed
* Multiple calls to `App::data` with the same type now keeps the latest call's data. [#1906]
### Removed
* Public field of `web::Path` has been made private. [#1894]
* Public field of `web::Query` has been made private. [#1894]
* `TestRequest::with_header`; use `TestRequest::default().insert_header()`. [#1869]
* `AppService::set_service_data`; for custom HTTP service factories adding application data, use the
layered data model by calling `ServiceRequest::add_data_container` when handling
requests instead. [#1906]

## 4.0.0-beta.1 - 2021-01-07

### Fixed

from `actix_web::error` module. [#1878]
