Release date: 10 Aug 2020
MariaDB 10.1 is a previous stable series of MariaDB. It is an evolution of MariaDB 10.0 with several entirely new features not found anywhere else and with backported and reimplemented features from MySQL 5.6 and 5.7.
Thanks, and enjoy MariaDB!

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.
