• breaking: Update public dependencies. axum now requires
  • hyper 1.0
  • http 1.0
  • http-body 1.0
• breaking: axum now requires tower-http 0.5
• breaking: Remove deprecated WebSocketUpgrade::max_send_queue
• breaking: The following types/traits are no longer generic over the request body
  (i.e. the B type param has been removed) (#1751 and #1789):
  • FromRequestParts
  • FromRequest
  • HandlerService
  • HandlerWithoutStateExt
  • Handler
  • LayeredFuture
  • Layered
  • MethodRouter
  • Next
  • RequestExt
  • RouteFuture
  • Route
  • Router
• breaking: axum no longer re-exports hyper::Body as that type is removed
  in hyper 1.0. Instead axum has its own body type at axum::body::Body (#1751)
• breaking: extract::BodyStream has been removed as body::Body
  implements Stream and FromRequest directly (#1751)
• breaking: Change sse::Event::json_data to use axum_core::Error as its error type (#1762)
• breaking: Rename DefaultOnFailedUpdgrade to DefaultOnFailedUpgrade (#1664)
• breaking: Rename OnFailedUpdgrade to OnFailedUpgrade (#1664)
• breaking: TypedHeader has been move to axum-extra (#1850)
• breaking: Removed re-exports of Empty and Full. Use
  axum::body::Body::empty and axum::body::Body::from respectively (#1789)
• breaking: The response returned by IntoResponse::into_response must use
  axum::body::Body as the body type. axum::response::Response does this
  (#1789)
• breaking: Removed the BoxBody type alias and its box_body
  constructor. Use axum::body::Body::new instead (#1789)
• breaking: Remove RawBody extractor. axum::body::Body implements FromRequest directly (#1789)
• breaking: The following types from http-body no longer implement IntoResponse:
  • Full, use Body::from instead
  • Empty, use Body::empty instead
  • BoxBody, use Body::new instead
  • UnsyncBoxBody, use Body::new instead
  • MapData, use Body::new instead
  • MapErr, use Body::new instead
• added: Add axum::extract::Request type alias where the body is axum::body::Body (#1789)
• added: Add Router::as_service and Router::into_service to workaround
  type inference issues when calling ServiceExt methods on a Router (#1835)
• breaking: Removed axum::Server as it was removed in hyper 1.0. Instead
  use axum::serve(listener, service) or hyper/hyper-util for more configuration options (#1868)
• breaking: Only inherit fallbacks for routers nested with Router::nest.
  Routers nested with Router::nest_service will no longer inherit fallbacks (#1956)
• fixed: Don't remove the Sec-WebSocket-Key header in WebSocketUpgrade (#1972)
• added: Add axum::extract::Query::try_from_uri (#2058)
• added: Implement IntoResponse for Box<str> and Box<[u8]> ([#2035])
• breaking: Simplify MethodFilter. It no longer uses bitflags (#2073)
• fixed: Fix bugs around merging routers with nested fallbacks (#2096)
• fixed: Fix .source() of composite rejections (#2030)
• fixed: Allow unreachable code in #[debug_handler] (#2014)

• changed: For SSE, add space between field and value for compatibility (#2149)
• added: Add NestedPath extractor (#1924)
• added: Add handle_error function to existing ServiceExt trait (#2235)
• breaking: impl<T> IntoResponse(Parts) for Extension<T> now requires
  T: Clone, as that is required by the http crate (#1882)
• added: Add axum::Json::from_bytes (#2244)
• added: Implement FromRequestParts for http::request::Parts (#2328)
• added: Implement FromRequestParts for http::Extensions (#2328)
• fixed: Clearly document applying DefaultBodyLimit to individual routes (#2157)
