+# Generics and Static Code Analyzer
+
+With version 4.3 we have added support for generics and added better type support.
+
+* `EnumSet<T of Enum>`
+* `EnumMap<T of Enum>`
+
+Generic types will be detected by [PHPStan](https://phpstan.org/) and [Psaml](https://psalm.dev/).
+
+Additionally, we have developed an [extension for PHPStan](https://github.com/marc-mabe/php-enum-phpstan/)
+to make enumerator accessor methods known.
