Breakwise 0.3.0 ships an offline CLI for its open registry of tested Python breaking changes
Released Oct 31, pip install breakwise bundles a copy of the registry so breakwise explain BW-2026-0001 shows a notice offline: the package, the release that breaks your code, and a before-and-after fix that's run against real PyPI releases before it's accepted. A command that finds the code an upgrade breaks is next, and the notices are CC BY 4.0 if you want to feed them to your agent (GitHub).
