+  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.

-# 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]

-//! Helper and convenience macros for Actix-web.
+//! Macros for reducing boilerplate code in Actix Web applications.
 //!
-//! ## Runtime Setup
+//! ## Actix Web Re-exports
+//! Actix Web re-exports a version of this crate in it's entirety so you usually don't have to
+//! specify a dependency on this crate explicitly. Sometimes, however, updates are made to this
+//! crate before the actix-web dependency is updated. Therefore, code examples here will show
+//! explicit imports. Check the latest [actix-web attributes docs] to see which macros
+//! are re-exported.
 //!
-//! - [main](attr.main.html)
-//!
-//! ## Resource Macros:
-//!
-//! - [get](attr.get.html)
-//! - [post](attr.post.html)
-//! - [put](attr.put.html)
-//! - [delete](attr.delete.html)
-//! - [head](attr.head.html)
-//! - [connect](attr.connect.html)
-//! - [options](attr.options.html)
-//! - [trace](attr.trace.html)
-//! - [patch](attr.patch.html)
-//!
-//! ### Attributes:
-//!
-//! - `"path"` - Raw literal string with path for which to register handle. Mandatory.
-//! - `guard="function_name"` - Registers function as guard using `actix_web::guard::fn_guard`
-//! - `wrap="Middleware"` - Registers a resource middleware.
-//!
-//! ### Notes
-//!
-//! Function name can be specified as any expression that is going to be accessible to the generate
-//! code (e.g `my_guard` or `my_module::my_guard`)
-//!
-//! ### Example:
+//! # Runtime Setup
+//! Used for setting up the actix async runtime. See [main] macro docs.
 //!
 //! ```rust
-//! use actix_web::HttpResponse;
-//! use actix_web_codegen::get;
-//!
-//! #[get("/test")]
-//! async fn async_test() -> Result<HttpResponse, actix_web::Error> {
-//!     Ok(HttpResponse::Ok().finish())
+//! #[actix_web_codegen::main] // or `#[actix_web::main]` in Actix Web apps
+//! async fn main() {
+//!     async { println!("Hello world"); }.await
 //! }
 //! ```
+//!
+//! # Single Method Handler
+//! There is a macro to set up a handler for each of the most common HTTP methods that also define
+//! additional guards and route-specific middleware.
+//!
+//! See docs for: [GET], [POST], [PATCH], [PUT], [DELETE], [HEAD], [CONNECT], [OPTIONS], [TRACE]
+//!
+//! ```rust
+//! # use actix_web::HttpResponse;
+//! # use actix_web_codegen::get;
+//! #[get("/test")]
+//! async fn get_handler() -> HttpResponse {
+//!     HttpResponse::Ok().finish()
+//! }
+//! ```
+//!
+//! # Multiple Method Handlers
+//! Similar to the single method handler macro but takes one or more arguments for the HTTP methods
+//! it should respond to. See [route] macro docs.
+//!
+//! ```rust
+//! # use actix_web::HttpResponse;
+//! # use actix_web_codegen::route;
+//! #[route("/test", method="GET", method="HEAD")]
+//! async fn get_and_head_handler() -> HttpResponse {
+//!     HttpResponse::Ok().finish()
+//! }
+//! ```

+/// Request-local data extractor.
+///
+/// Request-local data is arbitrary data attached to an individual request, usually
+/// by middleware. It can be set via `extensions_mut` on [`HttpRequest`][htr_ext_mut]
+/// or [`ServiceRequest`][srv_ext_mut].
+///
+/// Unlike app data, request data is dropped when the request has finished processing. This makes it
+/// useful as a kind of messaging system between middleware and request handlers. It uses the same
+/// types-as-keys storage system as app data.
+///
+/// # Mutating Request Data
+/// Note that since extractors must output owned data, only types that `impl Clone` can use this
+/// extractor. A clone is taken of the required request data and can, therefore, not be directly
+/// mutated in-place. To mutate request data, continue to use [`HttpRequest::extensions_mut`] or
+/// re-insert the cloned data back into the extensions map. A `DerefMut` impl is intentionally not
+/// provided to make this potential foot-gun more obvious.
+///
+/// # Example
+/// ```rust,no_run
+/// # use actix_web::{web, HttpResponse, HttpRequest, Responder};
+///
+/// #[derive(Debug, Clone, PartialEq)]
+/// struct FlagFromMiddleware(String);
