+
+
+## 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.

 ## 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

-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at fafhrd91@gmail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
-
-## Attribution
-
-This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

-      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:

-      (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.
