A file format compatibility bug that was introduced in MariaDB 10.1.0 was fixed in MariaDB 10.1.21.

Using page_compression or non-default innodb_page_size created files that were incompatible with MariaDB 10.0 or MySQL 5.6. MariaDB 10.1.21 and higher will convert affected files from earlier MariaDB 10.1 releases to a compatible format.

This prevents a downgrade to earlier MariaDB 10.1 versions.

See the commit for details.
