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-is@16.13.1..17.0.2

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

Quickstart

Removed

Gone at runtime, with no replacement found under another name. Imports of these fail.

  • AsyncModeobject
  • ConcurrentModeobject

Signature changes

Still exported, but the number of arguments it reads changed.

  • isAsyncMode1 → 0 arguments
  • isConcurrentMode1 → 0 arguments

An export diff shows what a release removed or re-signatured, not behaviour changes: read the changelog for those. Extracted Oct 20, 2026. react-is on lurq.
