[03-Jan-2008]
The PHP development team would like to announce the immediate availability of PHP 4.4.8. It continues to improve the security and the stability of the 4.4 branch and all users are strongly encouraged to upgrade to it as soon as possible. This release wraps up all the outstanding patches for the PHP 4.4 series, and is therefore the last normal PHP 4.4 release. If necessary, releases to address security issues could be made until 2008-08-08.
因为php官方(http://www.php.net)已经公告对原有php4版本已于2007-12-31停止新的开发,并于2008-8-8停止对产品进行安全更新。
我司因有部分服务器使用php4版本,特通告用户提前做好代码升级到php5版本,以保持与官方最新技术支持与安全更新。php4版本的截止支持也到2008-08-08结束,届时所有php4版本都将升级到最新的php5版本使用。
