+Breacking Change "Introduce PHP 7.0 TypeHints"
+==============================================
+
+As PHP evolved, we now migrate the whole code base to use PHP 7.0 type hints.
+We do not use PHP 7.1 Type Hints, as some customers still need PHP 7.0 support.
+
+Also we added missing methods to interfaces, that were already used in code.
+
+As this leads to changed method signatures, most custom implementations of interfaces, or overwrites
+of existing methods are broken.
+
+To fix, just update the signatures as pointed out by PHP while running the code.
