Critical: MariaDB Is Not a Drop-In Replacement for MySQL 8.0
MariaDB was a true drop-in replacement for MySQL 5.5 and 5.6. Modern versions diverge significantly from MySQL 8.0. When working with MariaDB, never assume MySQL 8.0 behavior, syntax, or tooling applies without verification.
The two databases share a common origin but have evolved independently. MariaDB has features MySQL lacks, MySQL has features MariaDB lacks, and several shared features behave differently.
Requires: MariaDB Community Server 10.5+ for full feature parity discussed here. Current LTS is 11.8 (GA May 2025).
Default context: Assume MariaDB 11.8 LTS unless the user states another version. Features marked 12.x or 13.0 may be suggested when relevant (including as upgrade options), but always state the minimum version — do not present them as available on 11.8.
