Fatal error: Uncaught TypeError: round(): Argument #1 ($num) must be of type int|float, null given in /tmp/vendor/phpmetrics/phpmetrics/src/Hal/Violation/Package/StableDependenciesPrinciple.php:66

changing src/Hal/Violation/Package/StableDependenciesPrinciple.php:66
to
$instability = $this->metric->getInstability()??0

fixes the issue, but i'm not sure it's a proper fix...

New version v3.0.0rc5 fixes this. Thanks for notice it!
