Thank you for submitting the PR! Given some past experiences with the crate (which is great, but can be tricky to get right at times), we'd like to exercise a bit of caution. We'll assess the stability of version 1.5.0 and determine if we still need to pin to a specific version moving forward.

@ysaito1001 @landonxjames Just landed 1.6.0 which should be considerably less fragile due to moving to runtime feature detection, rather than the hybrid runtime / compile time detection previously used.

Also expanded our test and build coverage, including more OSes and platforms.

Last, but certainly not least, pretty dramatically improved Graviton performance (~53GiB/s on Graviton4 now, a ~36% bump).

Let me know if I can help in any way with testing, validation, and release. 👍
