# Unreleased

- Overall:
  - **added:** Add default feature `tower-log` which exposes `tower`'s `log` feature. ([#218](https://github.com/tokio-rs/axum/pull/218))
  - **fixed:** Overall compile time improvements. If you're having issues with compile time
    please file an issue! ([#184](https://github.com/tokio-rs/axum/pull/184)) ([#198](https://github.com/tokio-rs/axum/pull/198)) ([#220](https://github.com/tokio-rs/axum/pull/220))
  - **fixed:** Remove `prelude`. Explicit imports are now required ([#195](https://github.com/tokio-rs/axum/pull/195))
  - **changed:** Replace `body::BoxStdError` with `axum::Error`, which supports downcasting ([#150](https://github.com/tokio-rs/axum/pull/150))
- Routing:
  - **added:** Add dedicated `Router` to replace the `RoutingDsl` trait ([#214](https://github.com/tokio-rs/axum/pull/214))
  - **added:** Add `Router::or` for combining routes ([#108](https://github.com/tokio-rs/axum/pull/108))
  - **fixed:** Support matching different HTTP methods for the same route that aren't defined
    together. So `Router::new().route("/", get(...)).route("/", post(...))` now
    accepts both `GET` and `POST`. Previously only `POST` would be accepted ([#224](https://github.com/tokio-rs/axum/pull/224))
  - **fixed:** `get` routes will now also be called for `HEAD` requests but will always have
    the response body removed ([#129](https://github.com/tokio-rs/axum/pull/129))
  - **changed:** Replace `axum::route(...)` with `axum::Router::new().route(...)`. This means
    there is now only one way to create a new router. Same goes for
    `axum::routing::nest`. ([#215](https://github.com/tokio-rs/axum/pull/215))
  - **changed:** Implement `routing::MethodFilter` via [`bitflags`](https://crates.io/crates/bitflags) ([#158](https://github.com/tokio-rs/axum/pull/158))
  - **changed:** Move `handle_error` from `ServiceExt` to `service::OnMethod` ([#160](https://github.com/tokio-rs/axum/pull/160))
- Extractors:
  - **added:** Make `FromRequest` default to being generic over `body::Body` ([#146](https://github.com/tokio-rs/axum/pull/146))
  - **added:** Implement `std::error::Error` for all rejections ([#153](https://github.com/tokio-rs/axum/pull/153))
  - **added:** Add `OriginalUri` for extracting original request URI in nested services ([#197](https://github.com/tokio-rs/axum/pull/197))
  - **added:** Implement `FromRequest` for `http::Extensions` ([#169](https://github.com/tokio-rs/axum/pull/169))
  - **added:** Make `RequestParts::{new, try_into_request}` public so extractors can be used outside axum ([#194](https://github.com/tokio-rs/axum/pull/194))
  - **added:** Implement `FromRequest` for `axum::body::Body` ([#241](https://github.com/tokio-rs/axum/pull/241))
  - **changed:** Removed `extract::UrlParams` and `extract::UrlParamsMap`. Use `extract::Path` instead ([#154](https://github.com/tokio-rs/axum/pull/154))
  - **changed:** `extractor_middleware` now requires `RequestBody: Default` ([#167](https://github.com/tokio-rs/axum/pull/167))
  - **changed:** Convert `RequestAlreadyExtracted` to an enum with each possible error variant ([#167](https://github.com/tokio-rs/axum/pull/167))
  - **changed:** `extract::BodyStream` is no longer generic over the request body ([#234](https://github.com/tokio-rs/axum/pull/234))
  - **changed:** `extract::Body` has been renamed to `extract::RawBody` to avoid conflicting with `body::Body` ([#233](https://github.com/tokio-rs/axum/pull/233))
  - **changed:** `RequestParts` changes ([#153](https://github.com/tokio-rs/axum/pull/153))
      - `method` new returns an `&http::Method`
      - `method_mut` new returns an `&mut http::Method`
      - `take_method` has been removed
      - `uri` new returns an `&http::Uri`
      - `uri_mut` new returns an `&mut http::Uri`
      - `take_uri` has been removed
  - **changed:** Remove several rejection types that were no longer used ([#153](https://github.com/tokio-rs/axum/pull/153)) ([#154](https://github.com/tokio-rs/axum/pull/154))
- Responses:
  - **added:** Add `Headers` for easily customizing headers on a response ([#193](https://github.com/tokio-rs/axum/pull/193))
  - **added:** Add `Redirect` response ([#192](https://github.com/tokio-rs/axum/pull/192))
  - **added:** Add `body::StreamBody` for easily responding with a stream of byte chunks ([#237](https://github.com/tokio-rs/axum/pull/237))
  - **changed:** Add associated `Body` and `BodyError` types to `IntoResponse`. This is
    required for returning responses with bodies other than `hyper::Body` from
    handlers. See the docs for advice on how to implement `IntoResponse` ([#86](https://github.com/tokio-rs/axum/pull/86))
  - **changed:** `tower::util::Either` no longer implements `IntoResponse` ([#229](https://github.com/tokio-rs/axum/pull/229))
- SSE:
  - **added:** Add `response::sse::Sse`. This implements SSE using a response rather than a service ([#98](https://github.com/tokio-rs/axum/pull/98))
  - **changed:** Remove `axum::sse`. Its been replaced by `axum::response::sse` ([#98](https://github.com/tokio-rs/axum/pull/98))
- WebSockets:
  - **changed:** Change WebSocket API to use an extractor plus a response ([#121](https://github.com/tokio-rs/axum/pull/121))
  - **changed:** Make WebSocket `Message` an enum ([#116](https://github.com/tokio-rs/axum/pull/116))
  - **changed:** `WebSocket` now uses `Error` as its error type ([#150](https://github.com/tokio-rs/axum/pull/150))
- Misc
  - **changed:** `EmptyRouter` now requires the response body to implement `Send + Sync + 'static'` ([#108](https://github.com/tokio-rs/axum/pull/108))
  - **changed:** `Router::check_infallible` now returns a `CheckInfallible` service. This
    is to improve compile times ([#198](https://github.com/tokio-rs/axum/pull/198))
  - **changed:** `Router::into_make_service` now returns `routing::IntoMakeService` rather than
    `tower::make::Shared` ([#229](https://github.com/tokio-rs/axum/pull/229))
  - **changed:** All usage of `tower::BoxError` has been replaced with `axum::BoxError` ([#229](https://github.com/tokio-rs/axum/pull/229))
  - **changed:** Several response future types have been moved into dedicated
    `future` modules ([#133](https://github.com/tokio-rs/axum/pull/133))
  - **changed:** `EmptyRouter`, `ExtractorMiddleware`, `ExtractorMiddlewareLayer`,
    and `QueryStringMissing` no longer implement `Copy` ([#132](https://github.com/tokio-rs/axum/pull/132))
  - **changed:** `service::OnMethod`, `handler::OnMethod`, and `routing::Nested` have new response future types ([#157](https://github.com/tokio-rs/axum/pull/157))
