It wasn't possible to upgrade the SDK to a newer version because it required a lcobucci/jwt release that doesn't support PHP 8.1 anymore. This was fixed by changing the version requirement from ^5.4.2 to ^5.3.

The SDK is celebrating its 10th anniversary this month! If you’ve found value in my work on this project over the years, I’d be truly grateful if you considered showing your support by becoming a Sponsor. Thank you for helping keep this journey going!
