+Version 5.2.0-dev
+-----------------
+
+### 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.
