End of support for PHP 5.6 in self-managed hosting - December 12th, 2022
As you may know, PHP 5.6 reached its end of life a few years ago (January, 2017). The last security updates have been applied in December, 2018.
We understand that switching to a newer version of PHP can require some work, which was a reason to let you use it until now.
However, we have to move forward and stop maintaining deprecated versions of PHP which don't receive any security updates.
