What’s Changed

The Enterprise Upgrade (v0.5.0) 🚀

This major update adds powerful compliance, customization, and deprecation lifecycle controls for developers and organizations.

🌟 New Features

  • ⚠️ Deprecation Checker — When a public function or class is removed, the tool checks the base branch to see if it was marked with a deprecation warning first. Pre-deprecated removals are downgraded to medium severity; surprise removals stay high.
  • 🛡️ SARIF Output (--format sarif) — Export results in standardized SARIF JSON format for integration with GitHub’s native Security / Code Scanning dashboard.
  • 📝 API Changelog Generator (--changelog) — Generates a clean breakage-radar-changelog.md listing every public addition, removal, and signature change across Python, Go, and JS/TS files.
  • ⚙️ In-Manifest Configuration — Configure ignored paths, public directories, and severity overrides directly inside pyproject.toml or a breakage-radar.json file — no CLI flags required.
