`pqcrypto-mlkem` is unmaintained: upstream PQClean project being archived
Details
This crate provides Rust bindings to ML-KEM (FIPS 203) via C implementations from [PQClean](https://github.com/PQClean/PQClean). The PQClean project is being archived in or after July 2026 (see [PQClean/PQClean#604](https://github.com/PQClean/PQClean/issues/604)), after which no further security patches or bug fixes will be applied to the upstream implementations.
As a result, this crate will no longer receive updates. Users should migrate to the [`ml-kem`](https://crates.io/crates/ml-kem) crate, which provides a pure-Rust implementation of ML-KEM (FIPS 203).
