  • Removed the transitive runtime dependency regenerator-runtime and corresponding runtime imports from builds, reducing bundled polyfills.
  • No public APIs, exports, or signatures were changed; observable behavior should be identical except in environments that relied on the removed polyfill.

Walkthrough

Removed the transitive dependency regenerator-runtime and deleted its side-effect imports from clerk-js entry files and the package manifest; exported APIs and application logic were not modified.

Changes

Cohort / File(s)	Summary
Dependency configuration packages/clerk-js/package.json	Removed the regenerator-runtime dependency (0.14.1) from package.json; other dependencies unchanged.
Entry point imports packages/clerk-js/src/index.ts, packages/clerk-js/src/index.headless.ts, packages/clerk-js/src/index.headless.browser.ts, packages/clerk-js/src/index.legacy.browser.ts	Deleted the side-effect import regenerator-runtime/runtime from all listed entry files; no public API or control-flow changes.
Release metadata .changeset/remove-regenerator-runtime.md	Added a changeset documenting the removal for a patch release.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Repetitive, limited-scope edits: dependency removal and identical import deletions across multiple entry files.
• Review attention:
  • Confirm target build outputs and published bundles remain functional without the polyfill.
  • Verify CI/build matrices for older runtimes that might have depended on the runtime helper.

Poem

🐇 I hopped through lines and found a seam,
A tiny runtime left the team.
I nudged four files and closed the gate,
A lighter package — small and straight.
Crunching carrots, shipping clean 🍃
