5 July 2007 — A consortium of PHP developers has announced today that several leading Open Source PHP projects will be dropping support for older versions of PHP in upcoming releases of their software as of February 5, 2008 as part of a joint effort to move the PHP developer community fully onto PHP version 5.

The Symfony, Typo3, phpMyAdmin, Drupal, Propel, and Doctrine projects have all announced that their next release after February 5, 2008 will require PHP version 5.2 as part of a coordinated effort at GoPHP5.org, and have issued an open invitation to any other PHP projects and applications, both open source and proprietary, that want to participate in the effort.
