Debugging has been corrected, as have DOM properties. MBString has been upgraded to Unicode 16.0. PHPDBG has resolved issues with PCRE, PDO_PGSQL, and PQclosePrepare. Reflection has added the missing ReflectionProperty::hasHook[s]() methods are now fixed, SimpleXML has segmentation errors fixed, SOAP has issues solved, and TSRM prevents unrelated handles from being closed.
