[arch-general] Mariadb Tables Still Compatible with Backup Server Running Earlier Version?

[David C. Rankin]

This is more a general question following the mariadb feature update to
10.4.6-1. Do the tables remain compatible with servers running earlier
versions of mariadb?

What happens if a backup from an earlier version has to be rolled into the new
version?

Or more importantly, can a backup from the new version be used to update
servers running earlier versions of mariadb?

(I have the same database running on Arch with backup handled by openSuSE,
still running 10.0.35)

https://wiki.archlinux.org/index.php/MariaDB doesn't mention anything special.
Nor does https://mariadb.com/kb/en/library/changes-improvements-in-mariadb-104/

Any help or comment would be appreciated.
