We will be removing PHP 5.2.17 from all servers in the near future.
If you have scripts that require these older versions, those scripts will no longer function on our service.
Users that have PHP 5.2.17 selected will be updated to 5.3.28.
When 5.3 is removed, those users will be updated to 5.4.
Please be sure you have selected the highest PHP version that your script will run with. It is recommended to use PHP 5.4 or 5.5 for all sites. PHP 5.3 should bed avoided as it is nearing the end of its life. PHP 5.2 reached end of life more than 2 years ago.
Reminder: PHP 5.2 and 5.3 are slated to be removed from this system once 5.6 goes to release.
PHP 5.3 is now officially EOL'd, so no more security updates are coming to it.
For those that must use PHP 5.2, we can migrate you over to the NYC cPanel server.
That server runs each user in an isolated environment, so the risk of using the older version would only be with your sites.
We will be removing 5.2 and 5.3 from Plesk servers very soon. The NYC server will continue to offer older versions due to the way it is setup.
