MySQL and MariaDB have diverged quite a bit. I recently wrote a roundup of just the differences in table functionality and DDL, and despite keeping the post focused to that relatively-narrow topic, the list of differences is getting VERY long: https://www.skeema.io/blog/2023/05/10/mysql-vs-mariadb-schem...
Again, what is this thing you are trying to compare? I just see MariaDB and MariaDB =)
However, because of my blindness to actual MySQL, I have totally not paid attention to any differences between the two. I guess "drop in replacement" isn't actually true any more. Thanks for the info
