# Changes

## Unreleased - 2022-xx-xx
- Implement `Default` for `RateLimiter`.
- `RateLimiter` is marked `#[non_exhaustive]`; use `RateLimiter::default()` instead.
- In the middleware errors from the count function are matched and respond with `INTERNAL_SERVER_ERROR` if it's an unexpected error, instead of the default `TOO_MANY_REQUESTS`.
- Minimum supported Rust version (MSRV) is now 1.59 due to transitive `time` dependency.

- `Limiter::builder` now takes an `impl Into<String>`.

## 0.2.0 - 2022-03-22
- Update Actix Web dependency to v4 ecosystem.
- Update Tokio dependencies to v1 ecosystem.

## 0.1.4 - 2022-03-18
