We would like to let you know that the minimum required PHP version will be 5.3 for all our extensions starting November 2014. Since the PHP 5.2 EOL is already past 3 years, it is now time to move on and catch up the latest version. Since Joomla 3.x requires PHP 5.3.10 or above, you are already on right path if you are using Joomla 3.x. If you are still on Joomla 2.5x, you can upgrade to PHP 5.3 before upgrading any of our extensions.
As a first step, we have enforced PHP 5.3 as minimum requirement for CjLib 2.1.0. If you have not yet updated your PHP, it is recommended to continue using CjLib 2.0.x version till the time you upgrade your PHP. All other extensions will continue to work with PHP 5.2 till October 2014 and any future updates after this time will no longer supports PHP 5.2.
We request you to upgrade your PHP version as soon as possible because older versions may expose your sites to security vulnerabilities and bugs that have been fixed latest versions of PHP.
