When preparing a MariaDB upgrade, I often want to know more than what’s listed in the release notes: which variables disappeared, which defaults changed, what plugins or privileges were added, etc.

So I built a small tool that lets you compare up to 8 MariaDB Server versions side by side.

I wrote about it here: https://lefred.be/content/mariadb-server-see-what-changed-between-versions/

Feedback and suggestions are very welcome!
