# Unreleased

- Overall compile time improvements. If you're having issues with compile time
  please file an issue!
- Remove `prelude`. Explicit imports are now required.
- Make `FromRequest` default to being generic over `body::Body` ([#146](https://github.com/tokio-rs/axum/pull/146))
- Implement `std::error::Error` for all rejections ([#153](https://github.com/tokio-rs/axum/pull/153))
- Add `RoutingDsl::or` for combining routes ([#108](https://github.com/tokio-rs/axum/pull/108))
- Add `handle_error` to `service::OnMethod` ([#160](https://github.com/tokio-rs/axum/pull/160))
- Add `OriginalUri` for extracting original request URI in nested services ([#197](https://github.com/tokio-rs/axum/pull/197))
- Implement `FromRequest` for `http::Extensions`
- Implement SSE as an `IntoResponse` instead of a service ([#98](https://github.com/tokio-rs/axum/pull/98))
- Add `Headers` for easily customizing headers on a response ([#193](https://github.com/tokio-rs/axum/pull/193))
- Add `Redirect` response ([#192](https://github.com/tokio-rs/axum/pull/192))
- Make `RequestParts::{new, try_into_request}` public ([#194](https://github.com/tokio-rs/axum/pull/194))

## Breaking changes

- 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))
- Replace `body::BoxStdError` with `Error`, which supports downcasting ([#150](https://github.com/tokio-rs/axum/pull/150))
- `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))
- Change WebSocket API to use an extractor ([#121](https://github.com/tokio-rs/axum/pull/121))
- Make WebSocket `Message` an enum ([#116](https://github.com/tokio-rs/axum/pull/116))
- `WebSocket` now uses `Error` as its error type ([#150](https://github.com/tokio-rs/axum/pull/150))
- Ensure a `HandleError` service created from `ServiceExt::handle_error`
  _does not_ implement `RoutingDsl` as that could lead to confusing routing
  behavior ([#120](https://github.com/tokio-rs/axum/pull/120))
- Implement `routing::MethodFilter` via [`bitflags`](https://crates.io/crates/bitflags)
- Removed `extract::UrlParams` and `extract::UrlParamsMap`. Use `extract::Path` instead
- `EmptyRouter` now requires the response body to implement `Send + Sync + 'static'` ([#108](https://github.com/tokio-rs/axum/pull/108))
- `ServiceExt` has been removed and its methods have been moved to `RoutingDsl` ([#160](https://github.com/tokio-rs/axum/pull/160))
- `extractor_middleware` now requires `RequestBody: Default` ([#167](https://github.com/tokio-rs/axum/pull/167))
- Convert `RequestAlreadyExtracted` to an enum with each possible error variant ([#167](https://github.com/tokio-rs/axum/pull/167))
- `RoutingDsl::check_infallible` now returns a `CheckInfallible` service. This
  is to improve compile times.
- These future types have been moved
    - `extract::extractor_middleware::ExtractorMiddlewareResponseFuture` moved
      to `extract::extractor_middleware::future::ResponseFuture` ([#133](https://github.com/tokio-rs/axum/pull/133))
    - `routing::BoxRouteFuture` moved to `routing::future::BoxRouteFuture` ([#133](https://github.com/tokio-rs/axum/pull/133))
    - `routing::EmptyRouterFuture` moved to `routing::future::EmptyRouterFuture` ([#133](https://github.com/tokio-rs/axum/pull/133))
    - `routing::RouteFuture` moved to `routing::future::RouteFuture` ([#133](https://github.com/tokio-rs/axum/pull/133))
    - `service::BoxResponseBodyFuture` moved to `service::future::BoxResponseBodyFuture` ([#133](https://github.com/tokio-rs/axum/pull/133))
- The following types no longer implement `Copy` ([#132](https://github.com/tokio-rs/axum/pull/132))
    - `EmptyRouter`
    - `ExtractorMiddleware`
    - `ExtractorMiddlewareLayer`
    - `QueryStringMissing`
- `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
