pola-rs/polars published py-2.0.0-rc.1 on 2026-09-02, one week after py-1.44.1 on 08-26, and the announcement reached 394 points on Hacker News. The repo is at 39,644 stars with 2,870 open issues and was pushed this morning. The Rust crate is still on rs-0.55.2 from 08-06, so the Python and Rust version lines are diverging further, which matters if you pin both.
