v3.3.0

• 🚀 Added global augmentations for ReadableStream to the polyfill's type definitions. (#130)
  • This allows TypeScript users to use new methods such as ReadableStream.prototype[Symbol.asyncIterator](), even when TypeScript doesn't yet have a built-in type definition for them.
• 💥 The type definitions now require TypeScript 3.6 or higher. (#130) (Reverted in version 3.3.1)
• 👓 Align with spec version 4dc123a (#115, #134)
  • Added ReadableStream.from(asyncIterable), which creates a ReadableStream wrapping the given iterable or async iterable. This can also be used to wrap a native ReadableStream (e.g. a Response.body from fetch()), even if the native ReadableStream doesn't yet support async iteration. (#135)
  • Added Transformer.cancel method, which is called when the readable side of a TransformStream is cancelled or when its writable side is aborted.
  • Added min option to ReadableStreamBYOBReader.read(view, options).
  • Added support for AbortSignal.reason when aborting a pipe.
• 🚀 Buffers passed to ReadableStreamBYOBReader.read(view) will now be correctly transferred if either ArrayBuffer.prototype.transfer() or structuredClone() is available. (#136)
• 🐛 Prevent warnings from Bluebird about a promise being created within a handler but not being returned from a handler. (#131)
• 🏠 Improve internal DOMException polyfill. (#133)
