✨ 🚀 Features

• support web standard modules ([0c8eaf7e6](https://github.com/ReactiveX/rxjs/commit/0c8eaf7e6))
• ⚠️ observable (Symbol): remove `Symbol.observable` export ([#4466](https://github.com/ReactiveX/rxjs/pull/4466), [#7361](https://github.com/ReactiveX/rxjs/pull/7361))
• ⚠️ Subject.create: Removed the deprecated `Subject.create` method. ([d62ce6ebe](https://github.com/ReactiveX/rxjs/commit/d62ce6ebe))
• ⚠️ WebSocketSubject: no longer extends `Subject`. ([54f2f6ed1](https://github.com/ReactiveX/rxjs/commit/54f2f6ed1))
• webSocket: now allows input and output typing to differ ([c408acda1](https://github.com/ReactiveX/rxjs/commit/c408acda1))

🐛 🩹 Fixes

• TestScheduler: explicit unsubscribe works properly with `toEqual` ([#7403](https://github.com/ReactiveX/rxjs/pull/7403))
• config: `onStoppedNotification` and `onUnhandledError` will now always async dispatch ([#7344](https://github.com/ReactiveX/rxjs/pull/7344))
• fromEvent: `fromEvent` now handles symbols as event names ([#7339](https://github.com/ReactiveX/rxjs/pull/7339))
• fromEvent: passing a generic parameter is no longer deprecated ([#7406](https://github.com/ReactiveX/rxjs/pull/7406))
• observable (Symbol): `observable` (the `Symbol.observable` symbol instance) is no longer exported. Use a polyfill like `symbol-observable`, or use `Symbol.observable ?? '@@observable'` as a workaround."
• Subject.create: Removed the deprecated `Subject.create` method. If you need to create an object that is "half Observable, half Observer", you'll need to either bolt `next`, `error`, and `complete` handlers onto an `Observable` and property type the return... or you'll need to create your own class that is backed by an `Observable`. In any case, if the `Observer` and the `Observable` are so unrelated that you have to bolt them together, you're probably better off with those two objects separately. This is why `Subject.create` has been deprecated for so long.
• WebSocketSubject: `WebSocketSubject` is no longer `instanceof Subject`. Check for `instanceof WebSocketSubject` instead.
