PHPStan or similar can reveal these 👍

Thanks. I haven’t started with PHP8.1 yet but clearly I need to.

Just released a v3.2.3 which should fix this. Let me know.

Sweet, will test!

8.1 is a ***** with WordPress, I can’t believe core still is throwing deprecation warnings.

There’s lots to fix. I think/hope Requests comes soon.
