InfoWorld posted a news story that several open-source PHP (Hypertext Preprocessor) projects plan to stop supporting older versions of PHP in upcoming releases

The Go PHP 5 campaign, sponsored by several PHP proponents, is intended to move the PHP developer community fully onto the PHP version 5 platform. Among the projects backing the effort are Symfony, Typo3, phpMyAdmin, Drupal, Propel, and Doctrine. These vendors are committing to use PHP 5.2 in releases developed after Tuesday.
