You welcome. FYI, I have it up and running in Laravel Framework 9.43.0 (PHP 8.1). You may create a new release for PHP 8.1, I can help you if you need any help.
I've actually made a start on 8.1 support a few months ago on the 4.x branch, but I'm not quite sure about the current state. Feel free to check it out!
In order to support psr/log version 2 & 3 we need to define the versions in composer.json file. Verified that psr/log is backward compatible.
