+
+## `HttpResponse` as a `ResponseError`
+
+The implementation of `ResponseError` for `HttpResponse` has been removed.
+
+It was common in v3 to use `HttpResponse` as an error type in fallible handlers. The problem is that `HttpResponse` contains no knowledge or reference to the source error. Being able to guarantee that an "error" response actually contains an error reference makes middleware and other parts of Actix Web more effective.
+
+The error response builders in the `error` module were available in v3 but are now the best method for simple error responses without requiring you to implement the trait on your own custom error types. These builders can receive simple strings and third party errors that can not implement the `ResponseError` trait.
+
+A few common patterns are affected by this change:
+
+```diff
+- Err(HttpResponse::InternalServerError().finish())
++ Err(error::ErrorInternalServerError("reason"))
+
+- Err(HttpResponse::InternalServerError().body(third_party_error.to_string()))
++ Err(error::ErrorInternalServerError(err))
+
+- .map_err(|err| HttpResponse::InternalServerError().finish())?
++ .map_err(error::ErrorInternalServerError)?
+```

 # Changes
 
 ## Unreleased - 2021-xx-xx
+### Changed
+- Minimum supported Rust version (MSRV) is now 1.56 due to transitive `hashbrown` dependency.
 
 
+## 3.0.0 - 2022-03-07
+### Dependencies
+- Updated `actix-*` to Tokio v1-based versions. [#1813]
+- Updated `bytes` to `1.0`. [#1813]
+- Updated `cookie` to `0.16`. [#2555]
+- Updated `rand` to `0.8`.
+- Updated `rustls` to `0.20`. [#2414]
+- Updated `tokio` to `1`.
+
+### Added
+- `trust-dns` crate feature to enable `trust-dns-resolver` as client DNS resolver; disabled by default. [#1969]
+- `cookies` crate feature; enabled by default. [#2619]
+- `compress-brotli` crate feature; enabled by default. [#2250]
+- `compress-gzip` crate feature; enabled by default. [#2250]
+- `compress-zstd` crate feature; enabled by default. [#2250]
+- `client::Connector::handshake_timeout()` for customizing TLS connection handshake timeout. [#2081]
+- `client::ConnectorService` as `client::Connector::finish` method's return type [#2081]
+- `client::ConnectionIo` trait alias [#2081]
+- `Client::headers()` to get default mut reference of `HeaderMap` of client object. [#2114]
+- `ClientResponse::timeout()` for set the timeout of collecting response body. [#1931]
+- `ClientBuilder::local_address()` for binding to a local IP address for this client. [#2024]
+- `ClientRequest::insert_header()` method which allows using typed and untyped headers. [#1869]
+- `ClientRequest::append_header()` method which allows using typed and untyped headers. [#1869]
+- `ClientBuilder::add_default_header()` (and deprecate `ClientBuilder::header()`). [#2510]
+
+### Changed
+- `client::Connector` type now only has one generic type for `actix_service::Service`. [#2063]
+- `client::error::ConnectError` Resolver variant contains `Box<dyn std::error::Error>` type. [#1905]
+- `client::ConnectorConfig` default timeout changed to 5 seconds. [#1905]
+- `ConnectorService` type is renamed to `BoxConnectorService`. [#2081]
+- Fix http/https encoding when enabling `compress` feature. [#2116]
+- Rename `TestResponse::{header => append_header, set => insert_header}`. These methods now take a `TryIntoHeaderPair`. [#2094]
+- `ClientBuilder::connector()` method now takes `Connector<T, U>` type. [#2008]
+- Basic auth now accepts blank passwords as an empty string instead of an `Option`. [#2050]
+- Relax default timeout for `Connector` to 5 seconds (up from 1 second). [#1905]
+- `*::send_json()` and `*::send_form()` methods now receive `impl Serialize`. [#2553]
+- `FrozenClientRequest::extra_header()` now uses receives an `impl TryIntoHeaderPair`. [#2553]
+- Rename `Connector::{ssl => openssl}()`. [#2503]
+- `ClientRequest::send_body` now takes an `impl MessageBody`. [#2546]
+- Rename `MessageBody => ResponseBody` to avoid conflicts with `MessageBody` trait. [#2546]
+- Minimum supported Rust version (MSRV) is now 1.54.
+
+### Fixed
+- Send headers along with redirected requests. [#2310]
+- Improve `Client` instantiation efficiency when using `openssl` by only building connectors once. [#2503]
+- Remove unnecessary `Unpin` bounds on `*::send_stream`. [#2553]
+- `impl Future` for `ResponseBody` no longer requires the body type be `Unpin`. [#2546]
+- `impl Future` for `JsonBody` no longer requires the body type be `Unpin`. [#2546]
+- `impl Stream` for `ClientResponse` no longer requires the body type be `Unpin`. [#2546]
+
+### Removed
+- `compress` crate feature. [#2250]
+- `ClientRequest::set`; use `ClientRequest::insert_header`. [#1869]
+- `ClientRequest::set_header`; use `ClientRequest::insert_header`. [#1869]
+- `ClientRequest::set_header_if_none`; use `ClientRequest::insert_header_if_none`. [#1869]
