Hey, @freekmurze I have updated the PR.

[freekmurze]

It seems like every tests is failing. Please check locally and push a fix.

Changes description:

• Removed type hinting for $message argument in ArrayLogger.php for backward compatibility tests.
• Updated expectations in OptimizerTest to be in Unix style. (Apologies, I am on Windows and did not notice this issue).
• Replaced short closure functions with normal functions for backward compatibility tests.

Hopefully, Tests should be fixed now.

Thanks reviewing @freekmurze :)
