 # Changes
 
-## [Unreleased]
+## Unreleased - 2021-xx-xx
 
+
+## 4.0.0-beta.6 - 2021-04-17
 ### Added
+* `HttpResponse` and `HttpResponseBuilder` structs. [#2065]
 
+### Changed
+* Most error types are now marked `#[non_exhaustive]`. [#2148]
+
+[#2065]: https://github.com/actix/actix-web/pull/2065
+[#2148]: https://github.com/actix/actix-web/pull/2148
+
+
+## 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]
+
+[#2067]: https://github.com/actix/actix-web/pull/2067
+[#2093]: https://github.com/actix/actix-web/pull/2093
+[#2094]: https://github.com/actix/actix-web/pull/2094
+[#2097]: https://github.com/actix/actix-web/pull/2097
+[#2112]: https://github.com/actix/actix-web/pull/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]
+
+[#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]

+
+### Removed
+* Public field of `web::Path` has been made private. [#1894]

+## 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]

+  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]

 ## 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)`.
+
+
+## 3.0.0
+
+* The return type for `ServiceRequest::app_data::<T>()` was changed from returning a `Data<T>` to
+  simply a `T`. To access a `Data<T>` use `ServiceRequest::app_data::<Data<T>>()`.
+
+* Cookie handling has been offloaded to the `cookie` crate:
+  * `USERINFO_ENCODE_SET` is no longer exposed. Percent-encoding is still supported; check docs.
+  * Some types now require lifetime parameters.
+
+* The time crate was updated to `v0.2`, a major breaking change to the time crate, which affects
+  any `actix-web` method previously expecting a time v0.1 input.
+
 * Setting a cookie's SameSite property, explicitly, to `SameSite::None` will now
   result in `SameSite=None` being sent with the response Set-Cookie header.
   To create a cookie without a SameSite attribute, remove any calls setting same_site.
 
 * actix-http support for Actors messages was moved to actix-http crate and is enabled 
   with feature `actors`
+
 * content_length function is removed from actix-http.
   You can set Content-Length by normally setting the response body or calling no_chunking function. 
 
 * `BodySize::Sized64` variant has been removed. `BodySize::Sized` now receives a
   `u64` instead of a `usize`.
 
+* Code that was using `path.<index>` to access a `web::Path<(A, B, C)>`s elements now needs to use
+  destructuring or `.into_inner()`. For example:
+
+  ```rust
+  // Previously:
+  async fn some_route(path: web::Path<(String, String)>) -> String {
+    format!("Hello, {} {}", path.0, path.1)
+  }
+
+  // Now (this also worked before):
+  async fn some_route(path: web::Path<(String, String)>) -> String {
+    let (first_name, last_name) = path.into_inner();
+    format!("Hello, {} {}", first_name, last_name)
+  }
+  // Or (this wasn't previously supported):
+  async fn some_route(web::Path((first_name, last_name)): web::Path<(String, String)>) -> String {
+    format!("Hello, {} {}", first_name, last_name)
+  }
+  ```
+
+* `middleware::NormalizePath` can now also be configured to trim trailing slashes instead of always keeping one.
+  It will need `middleware::normalize::TrailingSlash` when being constructed with `NormalizePath::new(...)`,
+  or for an easier migration you can replace `wrap(middleware::NormalizePath)` with `wrap(middleware::NormalizePath::new(TrailingSlash::MergeOnly))`.
+
+* `HttpServer::maxconn` is renamed to the more expressive `HttpServer::max_connections`.
+
+* `HttpServer::maxconnrate` is renamed to the more expressive `HttpServer::max_connection_rate`.
+
+
 ## 2.0.0
 
 * `HttpServer::start()` renamed to `HttpServer::run()`. It also possible to

+* `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]
+
+### Removed
+* `ResponseBuilder::set`; use `ResponseBuilder::insert_header`. [#1869]
+* `ResponseBuilder::set_header`; use `ResponseBuilder::insert_header`. [#1869]
+* `ResponseBuilder::header`; use `ResponseBuilder::append_header`. [#1869]

+* `ResponseError` impl for `actix::MailboxError`. [#1969]
+
+### Documentation
+* Vastly improve docs and add examples for `HeaderMap`. [#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]

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the

-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "{}"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.
