Released reactphp/async v4.2.0, v3.2.0 and v2.2.0

[SimonFrings]

Released reactphp/async v4.2.0 today 🎉

• Feature: Add template annotations.
  (#40 by @WyriHaximus)

  All our public APIs now use Promise v3 template types to guide IDEs and static
  analysis tools (like PHPStan), helping with proper type usage and improving
  code quality:

  assertType('bool', await(resolve(true)));
  assertType('PromiseInterface<bool>', async(fn(): bool => true)());
  assertType('PromiseInterface<bool>', coroutine(fn(): bool => true));

• Feature: Full PHP 8.3 compatibility.

• Update test suite to avoid unhandled promise rejections.

– See https://github.com/reactphp/async/releases/tag/v4.2.0

We also released new reactphp/async v3.2.0 and reactphp/async v2.2.0 with these changes back-ported to older PHP versions.
