[#263]: https://github.com/actix/actix-extras/pull/263

## 0.5.1

- Remove unnecessary dependencies. [#259]

[#259]: https://github.com/actix/actix-extras/pull/259

## 0.5.0

`actix-identity` v0.5 is a complete rewrite. The goal is to streamline user experience and reduce maintenance overhead.

`actix-identity` is now designed as an additional layer on top of `actix-session` v0.7, focused on identity management. The identity information is stored in the session state, which is managed by `actix-session` and can be stored using any of the supported `SessionStore` implementations. This reduces the surface area in `actix-identity` (e.g., it is no longer concerned with cookies!) and provides a smooth upgrade path for users: if you need to work with sessions, you no longer need to choose between `actix-session` and `actix-identity`; they work together now!

`actix-identity` v0.5 has feature-parity with `actix-identity` v0.4; if you bump into any blocker when upgrading, please open an issue.

Changes:

- Minimum supported Rust version (MSRV) is now 1.57 due to transitive `time` dependency.
- `IdentityService`, `IdentityPolicy` and `CookieIdentityPolicy` have been replaced by `IdentityMiddleware`. [#246]
- Rename `RequestIdentity` trait to `IdentityExt`. [#246]
- Trying to extract an `Identity` for an unauthenticated user will return a `401 Unauthorized` response to the client. Extract an `Option<Identity>` or a `Result<Identity, actix_web::Error>` if you need to handle cases where requests may or may not be authenticated. [#246]

  Example:

  ```rust
  use actix_web::{http::header::LOCATION, get, HttpResponse, Responder};
  use actix_identity::Identity;

  #[get("/")]
  async fn index(user: Option<Identity>) -> impl Responder {
      if let Some(user) = user {
          HttpResponse::Ok().finish()
      } else {
          // Redirect to login page if unauthenticated
          HttpResponse::TemporaryRedirect()
              .insert_header((LOCATION, "/login"))
              .finish()
      }
  }
  ```
