Supply-chain check of a popular package (the 8,000 most used on each of npm, PyPI, crates.io and Go): latest version and release activity, maintainers or owners, install scripts, provenance, deprecation, retractions, and what changed since we began tracking it daily: releases by a new publisher account, owner changes, install scripts added, provenance dropped, source repository moved, yanks. Account names are never published. Signed.
