Thanks!!!
Anyway, can you explain why you need to bump the asyc-std version?

[jayvdb]

async-std 0.12 is 2 years old, and has some very old dependencies.

Saw the release notes and am curious: Why is this relevant? I would expect this to be done automatically by Cargo. Without a lock file the current one will be used and as it's a dev-dependency it's not relevant for the users of rstest as a library. (With the upcoming edition 2024 / resolver 3 it will use the latest one compatible with your current Rust version so its even more helpful to keep the actual required minimal version.)
Am I overlooking something?

I guess you saw it on https://github.com/la10736/rstest/releases/tag/v0.23.0 , which is automated and exhaustive.

Not on https://github.com/la10736/rstest/blob/master/CHANGELOG.md , which is manually curated.

This PR doesnt impact users much, which is why it would be omitted from CHANGELOG.md.

This PR did change the lib docs, so rstest users who copy&paste from the readme/docs would get a modern async-std. Telling users to depend on async-std v1.5 was really old advice.
