🔄 Migration Notes

If you had the old version running:

  1. No breaking changes for users - it's a new interface
  2. Old tests will fail (expected) - they test old functionality
  3. New tests are all passing - 29/29 ✅
  4. Documentation is updated everywhere
  5. Version bump to 2.0.0

Clean Up Old Tests (Optional)

The old test file __tests__/url-modifier.test.ts tests the old functionality. You can:

  • Delete it, or
  • Keep it for reference

The old lib/url-modifier.ts file is also no longer used but preserved.
