Does this break your code?
Run this in your project. It compares both releases against the names your code actually imports, locally, with no account and nothing sent to lurq:
npx lurqrun check-upgrade --upgrade react-dom@18.3.1..19.3.0
To have your coding agent check upgrades like this before it writes them, connect lurq to Claude Code, Cursor, VS Code or Codex:
npx lurqrun
