After upgrading to PHP 8.1, the WP_DEBUG_DISPLAY shows a deprecation warning for Kinsta MU Plugins. The warning is as follows:
Deprecated : Optional parameter $info declared before required parameter $options is implicitly treated as a required parameter in C:\xampp\htdocs\my-site\wp-content\mu-plugins\kinsta-mu-plugins\shared\class-shared.php on line 148
With the rollout/requirement to use PHP 8 in the near future, I wanted to clarify that this deprecation is either currently being looked into, or will have no adverse effects and can be ignored for the time being.
Thank you and have a great year!
