2021/9/24 Workers Runtime Release Notes

Changes this week:

  • The AbortController and AbortSignal objects are now available.
  • The Web Platform queueMicrotask API is now available.
  • It is now possible to use new EventTarget() and to create custom EventTarget subclasses.
  • The once option is now supported on addEventTarget to register event handlers that will be invoked only once.
  • Per the HTML specification, a listener passed in to the addEventListener function is allowed to either be a function or an object with a handleEvent member function. Previously, Workers only supported the function option, now it supports both.
  • The Event object now supports most standard methods and properties.
  • V8 updated from 9.3 to 9.4.
