Rayon 0.7 has been released, marking the first step toward Rayon 1.0. A key change is the introduction of the rayon-core crate (released at v1.0) to ensure a single global scheduler regardless of how many Rayon versions are in use — all users are urged to upgrade. Parallel iterators now reach feature parity with Rust's standard sequential iterators. New features include par_split(), find_first/last(), position_first/last(), rev(), a rayon::split function for custom iterators, improved thread configuration APIs, and experimental futures integration. Several breaking changes accompany the API reorganization toward 1.0 stability.
