+# Rust Client for the RabbitMQ HTTP API Change Log
+
+## v0.9.0 (Dec 24, 2024)
+
+### Breaking Changes
+
+ * To propagate more request context to the caller,
+   `crate::error::Error` was updated to provide a requset URL, a header map,
+   and a request body (if available).
+
+   This reason for doing this comes down to how `reqwest`'s `Response` functions
+   are designed: the ones that consume and parse the body also consume `self`,
+   which means propagating a `Response` to the caller is not very useless at best,
+   and arguably is misleading.
+
+### Enhancements
+
+ * `crate::api` now provides an async API. `crate::blocking_api` provides the
+   original synchronous API.

+
+ * `Client#overview` is a new function that corresponds to the `GET /api/overview` API endpoint.
