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 is-docker@3.0.0..4.0.0
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
An export diff shows what a release removed or re-signatured, not behaviour changes: read the changelog for those. Extracted Sep 10, 2026. is-docker on lurq.
