2023/2/27 Workers Runtime Release Notes

Changes this week:

  • Updated V8 10.9 → 11.0.
  • The headers.getSetCookie() method is a new fetch standard API for properly retrieving Set-Cookie headers. The behavior of the headers.entries() and headers.values() iterators are also modified to properly separate Set-Cookie header instances.
  • Added a compatibility flag to control whether uncaught exceptions from a worker invoked via dynamic dispatch (a Workers for Platforms feature) are passed along to the caller as the rejection of the fetch’s promise. Prior to this flag, the behavior is that uncaught exceptions in the invoked worker would manifest as empty 500 responses in the caller.
