NEW: [Web Apps] prune() API method removes invalid document roots. FIXED: [PEAR] conflicting PEAR_Exception declaration triggered in specific setting where SMTP server sends mail and PEAR dependency had been previously included by a forced inclusion via require_once.

CHANGED: [MySQL] Force update to November 9 security release for local privilege vulernability. [Terminal] backport IPv6 support
