Recently moved my CiviCRM install to a server running Debain 10 which brings:
- MariaDB 10.3.17
Everything seems to be working fine, except that in the system checks I'm now seeing this error/warning:
PHP MySQL Driver (libmysqlclient)
It is recommended, though not yet required, to upgrade your PHP MySQL driver (libmysqlclient) to >= 5.5.3 for utf8mb4 support.
The check seems to get its info from mysqli_get_client_info which on my server emits the following:
mysqlnd 5.0.12-dev - 20150407 - $Id: 7cc7cc96e675f6d72e5cf0f267f48e167c2abb23
This is surprising - 5.0?! What to do?
