## 0.2.0 (November 20, 2023)

- Adapt to new `tower_async::Service` contract:
  - `call` takes now `&self` instead of `&mut self`;
  - `call` returns `impl Future` instead of declared as `async fn`;

## 0.1.1 (July 18, 2023)

- Improve, expand and fix documentation;

## 0.1.0 (July 17, 2023)

This is the initial release of `tower-async`, a fork of <https://github.com/tower-rs/tower> and makes use of `async traits`
([RFC-3185: Static async fn in traits](https://rust-lang.github.io/rfcs/3185-static-async-fn-in-trait.html))
to simplify things and make it more easier to integrate async functions into middleware.

Notable differences:

- make use of `tower-async-service` instead of `tower-service`;
- make use of `tower-async-layer` instead of `tower-layer`;
- do not support features related to load balancing (we consider this out of scope);
- replace the `limit` module with an approach more fitting for `tower-async`.
