This includes releasing to: crates.io (libraries, binaries) GitHub releases cargo binstall PyPI Bioconda We also have some specific settings to ensure the distributed binaries use AVX2 SIMD instructions, as well as some configuration to distribute x86-64 binaries that transparently switch to a AVX-512 enabled implementation when possible. See also this earlier post on distributing Rust SIMD binaries. (TODO: Write on cargo-multivers for shipping AVX-512 compatible binaries. See this issue for a tricky fix.)
