During the month of November, 2021, LuxSci will be upgrading all web servers that are currently running PHP v7.3 to PHP v7.4.
After December 6th, 2021, PHP v7.3 will no longer be supported by the PHP development community and will no longer be receiving security updates. As such, using PHP v7.3 after that date is not an option for security reasons. See:https://endoflife.software/programming-languages/server-side-scripting/php
If you are on a server that is currently running PHP v7.3 and you are unsure if your web site fully supports PHP v7.4, we recommend that you review your site and verify support during the coming months, so that when the software on your server is updated, your site will keep on chugging along. If you are unsure if your server is running PHP v7.3, please contact LuxSci support or examine your dedicated server administration page. See also the list of backwards-incompatible changes to PHP:https://www.php.net/manual/en/migration74.incompatible.php
Dedicated server customers can request that we upgrade their servers to PHP v7.4 at any time; they do not have to wait for November.
There is no option to continue to use PHP 7.3 after December 6th, 2021. To do so would be to leave your web site open to attackers and out of compliance.
Customers whose servers are currently running PHP v7.4 are not affected by this maintenance.
LuxSci will soon support PHP v8.0 for dedicated customers; those interested in upgrading to PHP v8.0 can request a date from support. All customers on PHP v7 will be upgraded to PHP v8 in November of 2022, when PHP v7.4 reaches its end of life (we will make another announcement about that in about a year).
