Hello,

Our builds started failing when version 0.2.11 of ppv-lite86 was published to crates.io.

We are seeing failures such as:

    --> /usr/rust/cargo/registry/src/git.luolix.top-1ecc6299db9ec823/ppv-lite86-0.2.11/src/x86_64/sse2.rs:1481:28

Can you please yank this release? These changes seem to not be compatible with a semver point release.

I think this is a problem with our CI environment. Sorry for the false alarm. Researching.

No, it's a real bug. I already yanked the version. Thanks for reporting it! I'm still researching the issue.

The rust docs aren't currently accurate about the stability of some SIMD fns with const arguments, but I would have caught it if I'd run the MSRV build check. I'll introduce a strict release checklist.
