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 estree-util-is-identifier-name@2.1.0..3.0.0
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
Signature changes
Still exported, but the number of arguments it reads changed.
- cont1 → 2 arguments
- name1 → 2 arguments
An export diff shows what a release removed or re-signatured, not behaviour changes: read the changelog for those. Extracted Sep 10, 2026. estree-util-is-identifier-name on lurq.
