###
[`v0.19.0`](https://togithub.com/la10736/rstest/blob/HEAD/CHANGELOG.md#0190-202449)

[Compare
Source](https://togithub.com/la10736/rstest/compare/v0.18.2...v0.19.0)

##### Changed

- Defined `rust-version` for each crate (see
[#&#8203;227](https://togithub.com/la10736/rstest/issues/235))

##### Fixed

-   `#[once]` fixtures now require the returned type to be
[`Sync`](https://doc.rust-lang.org/std/marker/trait.Sync.html) to
prevent UB
when tests are executed in parallel. (see
[#&#8203;235](https://togithub.com/la10736/rstest/issues/235)
    for more details)

- `#[future(awt)]` and `#[awt]` now properly handle mutable (`mut`)
parameters by treating futures as immutable and
    treating the awaited rebinding as mutable.

</details>
