full changelog

Note: there are further relevant changes in axum-core's changelog

• breaking: Upgrade matchit to 0.8, changing the path parameter syntax from /:single and /*many to /{single} and /{*many}; the old syntax produces a panic to avoid silent change in behavior (#​2645)
• breaking: Require Sync for all handlers and services added to Router and MethodRouter (#​2473)
• breaking: The tuple and tuple_struct Path extractor deserializers now check that the number of parameters matches the tuple length exactly (#​2931)
• breaking: Move Host extractor to axum-extra (#​2956)
• breaking: Remove WebSocket::close. Users should explicitly send close messages themselves. (#​2974)
• breaking: Make serve generic over the listener and IO types (#​2941)
• breaking: Remove Serve::tcp_nodelay and WithGracefulShutdown::tcp_nodelay.
  See serve::ListenerExt for an API that let you set arbitrary TCP stream properties. (#​2941)
• breaking: Option<Path<T>> no longer swallows all error conditions,
  instead rejecting the request in many cases; see its documentation for details (#​2475)
• breaking: axum::extract::ws::Message now uses Bytes in place of Vec<u8>,
  and a new Utf8Bytes type in place of String, for its variants (#​3078)
• fixed: Skip SSE incompatible chars of serde_json::RawValue in Event::json_data (#​2992)
• fixed: Don't panic when array type is used for path segment (#​3039)
• fixed: Avoid setting content-length before middleware.
  This allows middleware to add bodies to requests without needing to manually set content-length (#​2897)
• change: Update minimum rust version to 1.75 (#​2943)
• changed: Upgraded tokio-tungstenite to 0.26 (#​3078)
• changed: Query/Form: Use serde_path_to_error to report fields that failed to parse (#​3081)
• added: Add method_not_allowed_fallback to set a fallback when a path matches but there is no handler for the given HTTP method (#​2903)
• added: Add NoContent as a self-described shortcut for StatusCode::NO_CONTENT (#​2978)
• added: Add support for WebSockets over HTTP/2. They can be enabled by changing get(ws_endpoint) handlers to any(ws_endpoint) (#​2894)
• added: Add MethodFilter::CONNECT, routing::connect[_service] and MethodRouter::connect[_service] (#​2961)
• added: Extend FailedToDeserializePathParams::kind enum with (ErrorKind::DeserializeError). This new variant captures both key, value, and message from named path parameters parse errors, instead of only deserialization error message in ErrorKind::Message. (#​2720)
