The paragraph at the top of this file needs to be updated, to link to the new release (in both places, and the date needs updating).

(We realise that this is annoying, and do have plans to make this simpler, but we haven't applied them yet.)

I'm not sure this crate needs to have a version, but I guess bumping it doesn't do any harm either.

Yeah, I saw the version, figured it should match, but it doesn't seem important.

I recommend setting all publish = false crates to version 0.0.0. That makes it obvious that it isn't currently being versioned.

So I dug into this a bit. The version field is currently missing in fearless_simd_tests, but present in the other two unpublished crates (macros and gen). It used to be required, but is optional as of Rust 1.75. I think we should be consistent. I'm wondering whether it's better to elide the version field or set them explicitly to 0.0.0 in all three crates.
