## v3.2.0 (2021-11-06)
* 👎 Deprecate `WritableStreamDefaultController.abortReason` ([#102](https://github.com/MattiasBuelens/web-streams-polyfill/pull/102))
* Use `WritableStreamDefaultController.signal.reason` instead.
* 👓 Align with [spec version `4b6b93c`](https://github.com/whatwg/streams/tree/4b6b93c69e531e2fe45a6ed4cb1484a7ba4eb8bb/) ([#103](https://github.com/MattiasBuelens/web-streams-polyfill/pull/103))
## v3.1.1 (2021-09-06)
* 🐛 Fix compatibility with TypeScript's DOM types for `ReadableStream` and `TransformStream` ([#85](https://github.com/MattiasBuelens/web-streams-polyfill/issues/85), [#86](https://github.com/MattiasBuelens/web-streams-polyfill/pull/86))
## v3.1.0 (2021-07-21)
* 🚀 Calling `ReadableStream.tee()` on a readable byte stream now returns two readable byte streams. ([#81](https://github.com/MattiasBuelens/web-streams-polyfill/pull/81))
* 🚀 Add `WritableStreamDefaultController.signal` and `.abortReason`. ([#81](https://github.com/MattiasBuelens/web-streams-polyfill/pull/81))
* `.signal` requires a global `AbortController` constructor to be available. If necessary, use a polyfill.
* 🐛 Make sure streams created with a different version of the polyfill do not pass the brand checks. ([#75](https://github.com/MattiasBuelens/web-streams-polyfill/issues/75), [#77](https://github.com/MattiasBuelens/web-streams-polyfill/pull/77))
* 👓 Align with [spec version `cada812`](https://github.com/whatwg/streams/tree/cada8129edcc4803b2878a7a3f5e1d8325dc0c23/) ([#79](https://github.com/MattiasBuelens/web-streams-polyfill/pull/79), [#81](https://github.com/MattiasBuelens/web-streams-polyfill/pull/81))
## v3.0.3 (2021-04-09)
* 💅 Change `Promise<void>` to `Promise<undefined>` in TypeScript type definitions ([#72](https://github.com/MattiasBuelens/web-streams-polyfill/pull/72))
* 🐛 Fix `ReadableStream.tee()` resolving its `cancel()` promise too early ([#73](https://github.com/MattiasBuelens/web-streams-polyfill/pull/73))
* 👓 Align with [spec version `6762cdb`](https://github.com/whatwg/streams/tree/6762cdb4c6421cfa0da1d834d5a14fdd7326aaa5/) ([#73](https://github.com/MattiasBuelens/web-streams-polyfill/pull/73))
## v3.0.2 (2021-02-10)
* 👓 Align with [spec version `200c971`](https://github.com/whatwg/streams/tree/200c971563b1a695fce3eebe6dab45c348ff0ac0/) ([#69](https://github.com/MattiasBuelens/web-streams-polyfill/pull/69))
## v3.0.1 (2020-11-12)
* 📝 Add documentation to type definitions ([#62](https://github.com/MattiasBuelens/web-streams-polyfill/pull/62))
* 👓 Align with [spec version `6cd5e81`](https://github.com/whatwg/streams/tree/6cd5e81f6191fed9e7d99ee73d4941e3060311ce/) ([#63](https://github.com/MattiasBuelens/web-streams-polyfill/pull/63))
* 🐛 Fix an issue where the polyfill could throw an error when resolving/rejecting `reader.closed` when it was already resolved/rejected ([#66](https://github.com/MattiasBuelens/web-streams-polyfill/issues/66), [#67](https://github.com/MattiasBuelens/web-streams-polyfill/pull/67))
## v3.0.0 (2020-07-20)
* 💥 Align with [spec version `62fe4c8`](https://github.com/whatwg/streams/tree/62fe4c8c0df34cec4ff28db9bfa69aec6c65e38d/) ([#52](https://github.com/MattiasBuelens/web-streams-polyfill/pull/52), [#57](https://github.com/MattiasBuelens/web-streams-polyfill/pull/57), [#59](https://github.com/MattiasBuelens/web-streams-polyfill/pull/59))
This includes the following **breaking changes**:
* All classes are now exposed globally. Concretely, this adds the following classes:
* `ReadableStreamDefaultController`
* `ReadableByteStreamController`
* `ReadableStreamBYOBRequest`
* `ReadableStreamDefaultReader`
* `ReadableStreamBYOBReader`
* `WritableStreamDefaultController`
* `WritableStreamDefaultWriter`
* `TransformStreamDefaultController`
* `ReadableStream.getIterator()` is renamed to `ReadableStream.values()`
* `ReadableByteStreamController.byobRequest` can be `null` (instead of `undefined`) if there is no current BYOB request.
* `ReadableStreamBYOBRequest.view` can be `null` (instead of `undefined`) if the BYOB request has already been responded to.
* Constructors and methods have stricter type checking for object arguments. For example, `new ReadableStream(null)` would previously behave like `new ReadableStream({})`, but now it throws a `TypeError` instead.
* Some constructors and methods may throw slightly different errors when given invalid arguments.
* Various byte-stream-related APIs now prohibit zero-length views or buffers.
* The async iterator of a `ReadableStream` now behaves more like an async generator, e.g. returning promises fulfilled with `{ value: undefined, done: true }` after `return()`ing the iterator, instead of returning a rejected promise.
* 💥 Updated TypeScript types to align with new specification ([#60](https://github.com/MattiasBuelens/web-streams-polyfill/pull/60))
While these are _technically_ breaking changes, you should only be affected if you manually reference these types from your code.
* `PipeOptions` is renamed to `StreamPipeOptions`
* `ReadResult` is replaced by `ReadableStreamDefaultReadResult` and `ReadableStreamBYOBReadResult`
* `ReadableStreamDefaultControllerCallback` is replaced by `UnderlyingSourceStartCallback` and `UnderlyingSourcePullCallback`
* `ReadableByteStreamControllerCallback` is replaced by `UnderlyingByteSourceStartCallback` and `UnderlyingByteSourcePullCallback`
* `ReadableStreamErrorCallback` is renamed to `UnderlyingSourceCancelCallback`
* `WritableStreamDefaultControllerStartCallback` is renamed to `UnderlyingSinkStartCallback`
* `WritableStreamDefaultControllerWriteCallback` is renamed to `UnderlyingSinkWriteCallback`
* `WritableStreamDefaultControllerCloseCallback` is renamed to `UnderlyingSinkCloseCallback`
* `WritableStreamErrorCallback` is renamed to `UnderlyingSinkAbortCallback`
* `TransformStreamDefaultControllerCallback` is replaced by `TransformerStartCallback` and `TransformerFlushCallback`
* `TransformStreamDefaultControllerTransformCallback` is renamed to `TransformerTransformCallback`
## v2.1.1 (2020-04-11)

However, we recommend migrating to a [variant sub-package](https://github.com/MattiasBuelens/web-streams-polyfill#usage) instead:
* `require('web-streams-polyfill/index.js')` ➡ `require('web-streams-polyfill')`

* 👓 Align with [spec version `2c8f35e`](https://github.com/whatwg/streams/tree/2c8f35ed23451ffc9b32ec37b56def4a5349abb1/)
* 🏠 Code moved from [creatorrr/web-streams-polyfill](https://github.com/creatorrr/web-streams-polyfill) to [MattiasBuelens/web-streams-polyfill](https://github.com/MattiasBuelens/web-streams-polyfill)
