2020/12/04 Workers Runtime Release Notes

Changes this week:

  • Durable Objects storage API now supports listing keys by prefix.
  • Improved error message when a single request performs more than 1000 KV operations to make clear that a per-request limit was reached, not a global rate limit.
  • wrangler dev previews should now honor non-default resource limits, e.g. longer CPU limits for those in the Workers Unbound beta.
  • Fixed off-by-one line numbers in worker exceptions.
  • Exceptions thrown in a Durable Object’s fetch() method are now tunneled to its caller.
  • Fixed a bug where a large Durable Object response body could cause the Durable Object to become unresponsive.
