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 express@4.22.3..5.2.1
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
Removed
Gone at runtime, with no replacement found under another name. Imports of these fail.
