PHP 5.1 Beta 2 is now available! A lot of work has been put into this upcoming release and we believe it is ready for public testing
Some of the key improvements of PHP 5.1 include:
* PDO (PHP Data Objects) - A new native database abstraction layer providing performance, ease-of-use, and flexibility.
* Significantly improved language performance mainly due to the 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.
