[Compare
Source](https://redirect.github.com/bheisler/criterion.rs/compare/0.5.1...0.6.0)

##### Changed

-   MSRV bumped to 1.80
- The `real_blackbox` feature no longer has any impact. Criterion always
uses `std::hint::black_box()` now.
Users of `criterion::black_box()` should switch to
`std::hint::black_box()`.
-   `clap` dependency unpinned.

##### Fixed

- gnuplot version is now correctly detected when using certain Windows
binaries/configurations that used to fail

##### Added

- Async benchmarking with Tokio may be done via a
`tokio::runtime::Handle`, not only a `tokio::runtime::Runtime`

</details>
