2021/12/2 Workers Runtime Release Notes

Changes this week:

  • The streams spec requires that methods returning promises must not throw synchronous errors. As part of the effort of making the streams implementation more spec compliant, we are converting a number of sync throws to async rejections.
  • Major V8 update: 9.6 → 9.7. See V8 release v9.7 · V8 for more details.
