PDO (PHP Data Objects) - A new native database abstraction layer providing performance, ease-of-use, and flexibility. Significantly improved performance including a new Zend Engine II execution architecture. The PCRE extension has been updated to PCRE 5.0. Many more improvements including lots of new functionality & many bug fixes, especially in regards to SOAP, streams and SPL. See the bundled NEWS file for a more complete list of changes. Celebrate the great efforts - another milestone - a great knowledge asset - and contribution - good for PHPNuke and osc2nuke
