I am considering upgrading to MW 1.3. Before I do I need to be sure about the MariaDB version requirements but they are not listed in the 'compatibility' section of the MW site here: https://www.mediawiki.org/wiki/Release_notes/1.30#Compatibility . Can anyone tell me what the min version of MariaDB for MW 1.30.0 is please? There is also a lack of MariaDB info in the compatibility sections of  a number of the earlier MW releases. I suggest it might be helpful to address this. Peter P
