Changes last week:

  • URL.canParse(...) is a new standard API for testing that an input string can be parsed successfully as a URL without the additional cost of creating and throwing an error.
  • The Workers-specific IdentityTransformStream and FixedLengthStream classes now support specifying a highWaterMark for the writable-side that is used for backpressure signaling using the standard writer.desiredSize/writer.ready mechanisms.
