php version required for Zend Navigation to work

Question

does anybody know what minimum php version do you need to get Zend Navigation working? If I recall it didn't work with 5.1 though it was long ago, not sure if I am not confusing something

Zend recommends the most current release of PHP for critical security and performance enhancements, and currently supports PHP 5.2.4 or later.
