I am wondering which version of Maria DB will work for the new IC 5. The admin panel says I won't be able to upgrade unless I have MySQL version 8.0.13 inatalled, however my host (and many others) only offer Maria DB. So, what Maria DB version will work for IC 5?

Thank you.

Officially, we support MySQL. This was always the case even with version 4. Many do use MariaDB as a dropin alternative, but its MySQL we support. In addition, its probably worth being aware, we have seen people lately have performance issues with MariaDB, as we optimise for MySQL 8

I had a client encounter slowness issues using MariaDB 10.3. Updating to 10.11 solved the problem. I am using version 10.11.5 locally without issues, but I know of others using version 11.x without problems. too.

I don't recommend using anything lower than 10.11 though.
