-## 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()`. As such, calling `NormalizePath::default()` will log a warning.
-  It is advised that the `new` method be used instead.
-  
-  Before: `#[get("/test/")]`  
-  After:  `#[get("/test")]`  
-
-  Alternatively, explicitly require trailing slashes: `NormalizePath::new(TrailingSlash::Always)`.
-
-* The `type Config` of `FromRequest` was removed.
-
-* Feature flag `compress` has been split into its supported algorithm (brotli, gzip, zstd).
-  By default all compression algorithms are enabled.
-  To select algorithm you want to include with `middleware::Compress` use following flags:
-  - `compress-brotli`
-  - `compress-gzip`
-  - `compress-zstd`
-  If you have set in your `Cargo.toml` dedicated `actix-web` features and you still want
-  to have compression enabled. Please change features selection like bellow:
-
-  Before: `"compress"`
-  After: `"compress-brotli", "compress-gzip", "compress-zstd"`
-
-
-## 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
-  `.await` on `run` method result, in that case it awaits server exit.
-
-* `App::register_data()` renamed to `App::app_data()` and accepts any type `T: 'static`.
-  Stored data is available via `HttpRequest::app_data()` method at runtime.
-
-* Extractor configuration must be registered with `App::app_data()` instead of `App::data()`
-
-* Sync handlers has been removed. `.to_async()` method has been renamed to `.to()`
-  replace `fn` with `async fn` to convert sync handler to async
-
-* `actix_http_test::TestServer` moved to `actix_web::test` module. To start
-  test server use `test::start()` or `test_start_with_config()` methods
-
-* `ResponseError` trait has been reafctored. `ResponseError::error_response()` renders
-  http response.
-
-* Feature `rust-tls` renamed to `rustls`
-
-  instead of
-
-    ```rust
-    actix-web = { version = "2.0.0", features = ["rust-tls"] }
-    ```
-
-  use
-
-    ```rust
-    actix-web = { version = "2.0.0", features = ["rustls"] }
-    ```
-
-* Feature `ssl` renamed to `openssl`
-
-  instead of
-
-    ```rust
-    actix-web = { version = "2.0.0", features = ["ssl"] }
-    ```
-
-  use
-
-    ```rust
-    actix-web = { version = "2.0.0", features = ["openssl"] }
-    ```
-* `Cors` builder now requires that you call `.finish()` to construct the middleware
-
-## 1.0.1
-
-* Cors middleware has been moved to `actix-cors` crate
-
-  instead of
-
-  ```rust
-  use actix_web::middleware::cors::Cors;
-  ```
-
-  use
-
-  ```rust
-  use actix_cors::Cors;
-  ```
-
-* Identity middleware has been moved to `actix-identity` crate
-
-  instead of
-
-  ```rust
-  use actix_web::middleware::identity::{Identity, CookieIdentityPolicy, IdentityService};
-  ```
-
-  use
-
-  ```rust
-  use actix_identity::{Identity, CookieIdentityPolicy, IdentityService};
-  ```
-
-
-## 1.0.0
-
-* Extractor configuration. In version 1.0 this is handled with the new `Data` mechanism for both setting and retrieving the configuration
-
-  instead of
-
-  ```rust
-
-  #[derive(Default)]
-  struct ExtractorConfig {
-     config: String,
-  }
-
-  impl FromRequest for YourExtractor {
-     type Config = ExtractorConfig;
-     type Result = Result<YourExtractor, Error>;
-
-     fn from_request(req: &HttpRequest, cfg: &Self::Config) -> Self::Result {
-         println!("use the config: {:?}", cfg.config);
-         ...
-     }
-  }
-
-  App::new().resource("/route_with_config", |r| {
-     r.post().with_config(handler_fn, |cfg| {
-         cfg.0.config = "test".to_string();
-     })
-  })
-
-  ```
-
-  use the HttpRequest to get the configuration like any other `Data` with `req.app_data::<C>()` and set it with the `data()` method on the `resource`
-
-  ```rust
-  #[derive(Default)]
-  struct ExtractorConfig {
-     config: String,
-  }
-
-  impl FromRequest for YourExtractor {
-     type Error = Error;
-     type Future = Result<Self, Self::Error>;
-     type Config = ExtractorConfig;
-
-     fn from_request(req: &HttpRequest, payload: &mut Payload) -> Self::Future {
-         let cfg = req.app_data::<ExtractorConfig>();
-         println!("config data?: {:?}", cfg.unwrap().role);
-         ...
-     }
-  }
-
-  App::new().service(
-     resource("/route_with_config")
-         .data(ExtractorConfig {
-             config: "test".to_string(),
-         })
-         .route(post().to(handler_fn)),
-  )
-  ```
-
-* Resource registration. 1.0 version uses generalized resource
-  registration via `.service()` method.
-
-  instead of
-
-  ```rust
-    App.new().resource("/welcome", |r| r.f(welcome))
-  ```
-
-  use App's or Scope's `.service()` method. `.service()` method accepts
-  object that implements `HttpServiceFactory` trait. By default
-  actix-web provides `Resource` and `Scope` services.
-
-  ```rust
-    App.new().service(
-        web::resource("/welcome")
-            .route(web::get().to(welcome))
-            .route(web::post().to(post_handler))
-  ```
-
-* Scope registration.
-
-  instead of
-
-  ```rust
-      let app = App::new().scope("/{project_id}", |scope| {
-            scope
-                .resource("/path1", |r| r.f(|_| HttpResponse::Ok()))
-                .resource("/path2", |r| r.f(|_| HttpResponse::Ok()))
-                .resource("/path3", |r| r.f(|_| HttpResponse::MethodNotAllowed()))
-      });
-  ```
-
-  use `.service()` for registration and `web::scope()` as scope object factory.
-
-  ```rust
-      let app = App::new().service(
-          web::scope("/{project_id}")
-              .service(web::resource("/path1").to(|| HttpResponse::Ok()))
-              .service(web::resource("/path2").to(|| HttpResponse::Ok()))
-              .service(web::resource("/path3").to(|| HttpResponse::MethodNotAllowed()))
-      );
-  ```
-
-* `.with()`, `.with_async()` registration methods have been renamed to `.to()` and `.to_async()`.
-
-  instead of
-
-  ```rust
-    App.new().resource("/welcome", |r| r.with(welcome))
-  ```
-
-  use `.to()` or `.to_async()` methods
-
-  ```rust
-    App.new().service(web::resource("/welcome").to(welcome))
-  ```
-
-* Passing arguments to handler with extractors, multiple arguments are allowed
-
-  instead of
-
-  ```rust
-  fn welcome((body, req): (Bytes, HttpRequest)) -> ... {
-    ...
-  }
-  ```
-
-  use multiple arguments
-
-  ```rust
-  fn welcome(body: Bytes, req: HttpRequest) -> ... {
-    ...
-  }
-  ```
-
-* `.f()`, `.a()` and `.h()` handler registration methods have been removed.
-  Use `.to()` for handlers and `.to_async()` for async handlers. Handler function
-  must use extractors.
-
-  instead of
-
-  ```rust
-    App.new().resource("/welcome", |r| r.f(welcome))
-  ```
-
-  use App's `to()` or `to_async()` methods
-
-  ```rust
-    App.new().service(web::resource("/welcome").to(welcome))
-  ```
-
-* `HttpRequest` does not provide access to request's payload stream.
-
-  instead of
-
-  ```rust
-  fn index(req: &HttpRequest) -> Box<Future<Item=HttpResponse, Error=Error>> {
-    req
-       .payload()
-       .from_err()
-       .fold((), |_, chunk| {
-            ...
-        })
-       .map(|_| HttpResponse::Ok().finish())
-       .responder()
-  }
-  ```
-
-  use `Payload` extractor
-
-  ```rust
-  fn index(stream: web::Payload) -> impl Future<Item=HttpResponse, Error=Error> {
-     stream
-       .from_err()
-       .fold((), |_, chunk| {
-            ...
-        })
-       .map(|_| HttpResponse::Ok().finish())
-  }
-  ```
-
-* `State` is now `Data`.  You register Data during the App initialization process
-  and then access it from handlers either using a Data extractor or using
-  HttpRequest's api.
-
-  instead of
-
-  ```rust
-    App.with_state(T)
-  ```
-
-  use App's `data` method
-
-  ```rust
-	App.new()
-       .data(T)
-  ```
-
-  and either use the Data extractor within your handler
-
-  ```rust
-    use actix_web::web::Data;
-
-	fn endpoint_handler(Data<T>)){
-      ...
-    }
-  ```
-
-  .. or access your Data element from the HttpRequest
-
-  ```rust
-	fn endpoint_handler(req: HttpRequest) {
-		let data: Option<Data<T>> = req.app_data::<T>();
-    }
-  ```
-
-
-* AsyncResponder is removed, use `.to_async()` registration method and `impl Future<>` as result type.
-
-  instead of
-
-  ```rust
-	use actix_web::AsyncResponder;
-
-    fn endpoint_handler(...) -> impl Future<Item=HttpResponse, Error=Error>{
-		...
-        .responder()
-	}
-  ```
-
-  .. simply omit AsyncResponder and the corresponding responder() finish method
-
-
-* Middleware
-
-  instead of
-
-  ```rust
-      let app = App::new()
-           .middleware(middleware::Logger::default())
-  ```
-
-  use `.wrap()` method
-
-  ```rust
-      let app = App::new()
-           .wrap(middleware::Logger::default())
-           .route("/index.html", web::get().to(index));
-  ```
-
-* `HttpRequest::body()`, `HttpRequest::urlencoded()`, `HttpRequest::json()`, `HttpRequest::multipart()`
-  method have been removed. Use `Bytes`, `String`, `Form`, `Json`, `Multipart` extractors instead.
-
-  instead of
-
-  ```rust
-  fn index(req: &HttpRequest) -> Responder {
-     req.body()
-       .and_then(|body| {
-          ...
-       })
-  }
-  ```
-
-  use
-
-  ```rust
-  fn index(body: Bytes) -> Responder {
-     ...
-  }
-  ```
-
-* `actix_web::server` module has been removed. To start http server use `actix_web::HttpServer` type
-
-* StaticFiles and NamedFile have been moved to a separate crate.
-
-  instead of `use actix_web::fs::StaticFile`
-
-  use `use actix_files::Files`
-
-  instead of `use actix_web::fs::Namedfile`
-
-  use `use actix_files::NamedFile`
-
-* Multipart has been moved to a separate crate.
-
-  instead of `use actix_web::multipart::Multipart`
-
-  use `use actix_multipart::Multipart`
-
-* Response compression is not enabled by default.
-  To enable, use `Compress` middleware, `App::new().wrap(Compress::default())`.
-
-* Session middleware moved to actix-session crate
-
-* Actors support have been moved to `actix-web-actors` crate
-
-* Custom Error
-
-  Instead of error_response method alone, ResponseError now provides two methods: error_response and render_response respectively. Where, error_response creates the error response and render_response returns the error response to the caller. 
-
-  Simplest migration from 0.7 to 1.0 shall include below method to the custom implementation of ResponseError:
-
-  ```rust
-  fn render_response(&self) -> HttpResponse {
-    self.error_response()
-  }
-  ```
-
-## 0.7.15
-
-* The `' '` character is not percent decoded anymore before matching routes. If you need to use it in
-  your routes, you should use `%20`.
-
-  instead of
-
-    ```rust
-    fn main() {
-         let app = App::new().resource("/my index", |r| {
-             r.method(http::Method::GET)
-                    .with(index);
-         });
-    }
-    ```
-
-  use
-
-    ```rust
-    fn main() {
-         let app = App::new().resource("/my%20index", |r| {
-             r.method(http::Method::GET)
-                    .with(index);
-         });
-    }
-    ```
-
-* If you used `AsyncResult::async` you need to replace it with `AsyncResult::future`
-
-
-## 0.7.4
-
-* `Route::with_config()`/`Route::with_async_config()` always passes configuration objects as tuple
-  even for handler with one parameter.
-
-
-## 0.7
-
-* `HttpRequest` does not implement `Stream` anymore. If you need to read request payload
-  use `HttpMessage::payload()` method.
-
-  instead of
-
-    ```rust
-    fn index(req: HttpRequest) -> impl Responder {
-         req
-            .from_err()
-            .fold(...)
-            ....
-    }
-    ```
-
-  use `.payload()`
-
-    ```rust
-    fn index(req: HttpRequest) -> impl Responder {
-         req
-            .payload()  // <- get request payload stream
-            .from_err()
-            .fold(...)
-            ....
-    }
-    ```
-
-* [Middleware](https://actix.rs/actix-web/actix_web/middleware/trait.Middleware.html)
-  trait uses `&HttpRequest` instead of `&mut HttpRequest`.
-
-* Removed `Route::with2()` and `Route::with3()` use tuple of extractors instead.
-
-    instead of
-
-    ```rust
-    fn index(query: Query<..>, info: Json<MyStruct) -> impl Responder {}
-    ```
-
-    use tuple of extractors and use `.with()` for registration:
-
-    ```rust
-    fn index((query, json): (Query<..>, Json<MyStruct)) -> impl Responder {}
-    ```
-
-* `Handler::handle()` uses `&self` instead of `&mut self`
-
-* `Handler::handle()` accepts reference to `HttpRequest<_>` instead of value
-
-* Removed deprecated `HttpServer::threads()`, use
-  [HttpServer::workers()](https://actix.rs/actix-web/actix_web/server/struct.HttpServer.html#method.workers) instead.
-
-* Renamed `client::ClientConnectorError::Connector` to
-  `client::ClientConnectorError::Resolver`
-
-* `Route::with()` does not return `ExtractorConfig`, to configure
-  extractor use `Route::with_config()`
-
-    instead of
-
-    ```rust
-    fn main() {
-         let app = App::new().resource("/index.html", |r| {
-             r.method(http::Method::GET)
-                    .with(index)
-                    .limit(4096);  // <- limit size of the payload
-         });
-    }
-    ```
-
-    use
-
-    ```rust
-
-    fn main() {
-         let app = App::new().resource("/index.html", |r| {
-             r.method(http::Method::GET)
-                    .with_config(index, |cfg| { // <- register handler
-                       cfg.limit(4096);  // <- limit size of the payload
-                     })
-         });
-    }
-    ```
-
-* `Route::with_async()` does not return `ExtractorConfig`, to configure
-  extractor use `Route::with_async_config()`
-
-
-## 0.6
-
-* `Path<T>` extractor return `ErrorNotFound` on failure instead of `ErrorBadRequest`
-
-* `ws::Message::Close` now includes optional close reason.
-  `ws::CloseCode::Status` and `ws::CloseCode::Empty` have been removed.
-
-* `HttpServer::threads()` renamed to `HttpServer::workers()`.
-
-* `HttpServer::start_ssl()` and `HttpServer::start_tls()` deprecated.
-  Use `HttpServer::bind_ssl()` and `HttpServer::bind_tls()` instead.
-
-* `HttpRequest::extensions()` returns read only reference to the request's Extension
-  `HttpRequest::extensions_mut()` returns mutable reference.
-
-* Instead of
-
-   `use actix_web::middleware::{
-        CookieSessionBackend, CookieSessionError, RequestSession,
-        Session, SessionBackend, SessionImpl, SessionStorage};`
-
-  use `actix_web::middleware::session`
-
-   `use actix_web::middleware::session{CookieSessionBackend, CookieSessionError,
-        RequestSession, Session, SessionBackend, SessionImpl, SessionStorage};`
-
-* `FromRequest::from_request()` accepts mutable reference to a request
-
-* `FromRequest::Result` has to implement `Into<Reply<Self>>`
-
-* [`Responder::respond_to()`](
-  https://actix.rs/actix-web/actix_web/trait.Responder.html#tymethod.respond_to)
-  is generic over `S`
-
-*  Use `Query` extractor instead of HttpRequest::query()`.
-
-   ```rust
-   fn index(q: Query<HashMap<String, String>>) -> Result<..> {
-       ...
-   }
-   ```
-
-   or
-
-   ```rust
-   let q = Query::<HashMap<String, String>>::extract(req);
-   ```
-
-* Websocket operations are implemented as `WsWriter` trait.
-  you need to use `use actix_web::ws::WsWriter`
-
-
