$wgDBmysql5 is poorly named. It has little to do with Mysql5, and is all about wheter the db connection is using the "utf8" or "binary" charset. It is still used in modern MediaWiki.

Generally speaking, I would probably reccomend against changing the value of this setting unless you're sure you know what you are doing. Depending on the charset that your db tables were created with, removing the setting could break things.

Hi Everyone,

We just finished a MediaWiki 1.30 migration. The iron is CentOS 7 x86_64 VM with PHP 7.8.1 and MariaDB 5.5.56.

According to https://www.mediawiki.org/wiki/Manual:$wgDBmysql5 it looks like we no longer need wgDBmysql5 in LocalSettings.php.

Do we still need wgDBmysql5?

Jeff
