+
+* 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| {

-
-      "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

-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-
-   3. Grant of Patent License. Subject to the terms and conditions of

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,

-      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.

-///
-/// # Usage

-/// jar.add_original(Cookie::new("second", "another"));
-/// ```
-///
-/// Cookies can be added via [add](#method.add) and removed via
-/// [remove](#method.remove). Finally, cookies can be looked up via
-/// [get](#method.get):
-///
-/// ```rust
-/// # use actix_http::cookie::{Cookie, CookieJar};
-/// let mut jar = CookieJar::new();
-/// jar.add(Cookie::new("a", "one"));

-/// ```
-///
-/// # Deltas
-///
-/// A jar keeps track of any modifications made to it over time. The
-/// modifications are recorded as cookies. The modifications can be retrieved
-/// via [delta](#method.delta). Any new `Cookie` added to a jar via `add`
-/// results in the same `Cookie` appearing in the `delta`; cookies added via
-/// `add_original` do not count towards the delta. Any _original_ cookie that is
-/// removed from a jar results in a "removal" cookie appearing in the delta. A
-/// "removal" cookie is a cookie that a server sends so that the cookie is
-/// removed from the client's machine.
-///
-/// Deltas are typically used to create `Set-Cookie` headers corresponding to
-/// the changes made to a cookie jar over a period of time.
-///
-/// ```rust
-/// # use actix_http::cookie::{Cookie, CookieJar};
-/// let mut jar = CookieJar::new();
-///
-/// // original cookies don't affect the delta
-/// jar.add_original(Cookie::new("original", "value"));
