This release contains backported features from the Async v4.2.0 release for those not yet on PHP 8.1+. Async v3 provides a compatible API, but may not take advantage of newer language features. We encourage upgrading to the latest version when possible.

• Feature: Add Promise v3 template types for all public functions. (#82 by @clue)

  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>', coroutine(fn(): bool => true));
  

• Feature: Full PHP 8.3 compatibility. (#83 by @clue)

• Update test suite to avoid unhandled promise rejections. (#80 by @clue)
