Improvements 🔧

• @readonly property cannot be passed by-ref (#​3850), #​12676, thanks @​staabm!
• ClassReflection - cannot be a subclass of final-overriden class (phpstan/phpstan-src@ed4ea0a)
• Deprecated ClassReflection::isSubclassOf(string $className) in favour of ClassReflection::isSubclassOfClass(ClassReflection $class)
  • If you just have string $className instead of ClassReflection and you are too lazy to get ClassReflection via ReflectionProvider, you can still use ClassReflection::is(string $className)
