Hello!
The package relies on guzzlehttp/guzzle 6.x which went EOL in 2023, so it's no longer receiving security updates. Which isn't great. 😃 Also, it makes it hard (read: impossible) to reconcile dependencies with codebases using 7.x (the current active version.) That's also not great. 😃
The good news is I reviewed the code and it doesn't suffer from any breaking changes, so it's a simple update.
