## Standing notes
- uptime-kuma 2.3.0 removed status-page sorting (performance issue); no migration needed.
- uptime-kuma 2.3.2 reverted SQLite to single-connection mode; Raspberry Pi users may need `UPTIME_KUMA_SQLITE_SINGLE_CONNECTION=true`.
- MariaDB 12.x is a stable long-term release series (12.3.2 released 2026-05-28).
- compose.mariadb.yml is an optional overlay for MariaDB backend; the default recipe uses SQLite (compose.yml only). The cc-ci tests use the default SQLite path.
- A one-step major jump from 11.8 → 12.x is safe for fresh deployments; for existing MariaDB deployments, test the upgrade path.
