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 fast-xml-parser@2.9.4..3.21.1
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
Signature changes
Still exported, but the number of arguments it reads changed.
- parse2 → 1 arguments
An export diff shows what a release removed or re-signatured, not behaviour changes: read the changelog for those. Extracted Oct 6, 2026. fast-xml-parser on lurq.
