 ob_startThe third parameter of ob_start changed from a boolean parameter called erase (which, if set to FALSE, would prevent the output buffer from being deleted until the script finished executing) to an integer parameter called flags. Unfortunately, this results in an API compatibility break for code written prior to PHP 5.4.0 that uses the third parameter.

 session_set_save_handlerAdded SessionHandlerInterface for implementing session handlers and SessionHandler to expose internal PHP session handlers.
 snmp_set_valueretrievalConstants SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY may be combined with SNMP_VALUE_OBJECT resulting different way of representing contents of value array element in return value of GET-function.
