Besides the previous PHP Release questions in this thread, the other related question, is; What Database Releases will XC 5.5.* run on?
Here:
https://support.x-cart.com/en/articles/5258766-x-cart-tech-stack we have MySQL 5.7+ AND/OR MariaDB 10.2+ listed, but in both cases the + is totally non-specific and therefore, it is pretty meaningless.
Can we have an Official X-Cart Confirmation of what the LATEST release of MySQL and MariaDB is fully supported by XC 5.5.* ?
