Added

• [8.4] Added support for __PROPERTY__ magic constant, represented using a Node\Scalar\MagicConst\Property node.
• [8.4] Added support for property hooks, which are represented using a new hooks subnode on Node\Stmt\Property and Node\Param, which contains an array of Node\PropertyHook.
• [8.4] Added support for asymmetric visibility modifiers. Property flags can now hold the additional bits Modifiers::PUBLIC_SET, Modifiers::PROTECTED_SET and Modifiers::PRIVATE_SET.
• [8.4] Added support for generalized exit function. For backwards compatibility, exit without argument or a single plain argument continues to use a Node\Expr\Exit_ node. Otherwise (e.g. if a named argument is used) it will be represented as a plain Node\Expr\FuncCall.
• Added support for passing enum values to various builder methods, like BuilderFactory::val().

Removed

• Removed support for alternative array syntax $array{0} from the PHP 8 parser. It is still supported by the PHP 7 parser. This is necessary in order to support property hooks.
