-## Unreleased - 2020-xx-xx
+## 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
+### Added
+* `Compat` middleware enabling generic response body/error type of middlewares like `Logger` and
+  `Compress` to be used in `middleware::Condition` and `Resource`, `Scope` services. [#1865]
+
+### Changed
+* Update `actix-*` dependencies to tokio `1.0` based versions. [#1813]
+* Bumped `rand` to `0.8`.
+* Update `rust-tls` to `0.19`. [#1813]
+* Rename `Handler` to `HandlerService` and rename `Factory` to `Handler`. [#1852]
+* The default `TrailingSlash` is now `Trim`, in line with existing documentation. See migration
+  guide for implications. [#1875]
+* Rename `DefaultHeaders::{content_type => add_content_type}`. [#1875]
+* MSRV is now 1.46.0.
+
+### Fixed
+* Added the underlying parse error to `test::read_body_json`'s panic message. [#1812]
+
+### Removed
+* Public modules `middleware::{normalize, err_handlers}`. All necessary middleware structs are now
+  exposed directly by the `middleware` module.
+* Remove `actix-threadpool` as dependency. `actix_threadpool::BlockingError` error type can be imported 
+  from `actix_web::error` module. [#1878]

+## 3.3.2 - 2020-12-01
+### Fixed
+* Removed an occasional `unwrap` on `None` panic in `NormalizePathNormalization`. [#1762]
+* Fix `match_pattern()` returning `None` for scope with empty path resource. [#1798]
+* Increase minimum `socket2` version. [#1803]

 ## Unreleased
 
+* The default `NormalizePath` behavior now strips trailing slashes by default. This was
+  previously documented to be the case in v3 but the behavior now matches. The effect is that
+  routes defined with trailing slashes will become inaccessible when
+  using `NormalizePath::default()`.
+  
+  Before: `#[get("/test/")`  
+  After: `#[get("/test")`  
+
+  Alternatively, explicitly require trailing slashes: `NormalizePath::new(TrailingSlash::Always)`.

+### Changed
+* Feature `cookies` is now optional and disabled by default. [#1981]
+* `ws::hash_key` now returns array. [#2035]
+* `ResponseBuilder::json` now takes `impl Serialize`. [#2052]
+
+### Removed

+* No notable changes.
+
+
+## 3.0.0-beta.2 - 2021-02-10
+### Added
+* `IntoHeaderPair` trait that allows using typed and untyped headers in the same methods. [#1869]
+* `ResponseBuilder::insert_header` method which allows using typed headers. [#1869]
+* `ResponseBuilder::append_header` method which allows using typed headers. [#1869]
+* `TestRequest::insert_header` method which allows using typed headers. [#1869]
+* `ContentEncoding` implements all necessary header traits. [#1912]
+* `HeaderMap::len_keys` has the behavior of the old `len` method. [#1964]
+* `HeaderMap::drain` as an efficient draining iterator. [#1964]
+* Implement `IntoIterator` for owned `HeaderMap`. [#1964]
+* `trust-dns` optional feature to enable `trust-dns-resolver` as client dns resolver. [#1969]
+
+### Changed
+* `ResponseBuilder::content_type` now takes an `impl IntoHeaderValue` to support using typed
+  `mime` types. [#1894]
+* Renamed `IntoHeaderValue::{try_into => try_into_value}` to avoid ambiguity with std
+  `TryInto` trait. [#1894]
+* `Extensions::insert` returns Option of replaced item. [#1904]
+* Remove `HttpResponseBuilder::json2()`. [#1903]
+* Enable `HttpResponseBuilder::json()` to receive data by value and reference. [#1903]
+* `client::error::ConnectError` Resolver variant contains `Box<dyn std::error::Error>` type. [#1905]
+* `client::ConnectorConfig` default timeout changed to 5 seconds. [#1905]
+* Simplify `BlockingError` type to a unit struct. It's now only triggered when blocking thread pool
+  is dead. [#1957]
+* `HeaderMap::len` now returns number of values instead of number of keys. [#1964]
+* `HeaderMap::insert` now returns iterator of removed values. [#1964]
+* `HeaderMap::remove` now returns iterator of removed values. [#1964]

+## 3.0.0-beta.1 - 2021-01-07
+### Added
+* Add `Http3` to `Protocol` enum for future compatibility and also mark `#[non_exhaustive]`.
+
+### Changed
+* Update `actix-*` dependencies to tokio `1.0` based versions. [#1813]
+* Bumped `rand` to `0.8`.
+* Update `bytes` to `1.0`. [#1813]
+* Update `h2` to `0.3`. [#1813]
+* The `ws::Message::Text` enum variant now contains a `bytestring::ByteString`. [#1864]
+
+### Removed
+* Deprecated `on_connect` methods have been removed. Prefer the new
+  `on_connect_ext` technique. [#1857]
+* Remove `ResponseError` impl for `actix::actors::resolver::ResolverError`
+  due to deprecate of resolver actor. [#1813]
+* Remove `ConnectError::SslHandshakeError` and re-export of `HandshakeError`.
+  due to the removal of this type from `tokio-openssl` crate. openssl handshake 
+  error would return as `ConnectError::SslError`. [#1813]
+* Remove `actix-threadpool` dependency. Use `actix_rt::task::spawn_blocking`.
+  Due to this change `actix_threadpool::BlockingError` type is moved into 
+  `actix_http::error` module. [#1878]
