Notable Changes
Innodb updated to 5.6.35
A file format compatibility bug that was introduced in MariaDB 10.1.0 was fixed. 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 will convert affected files from earlier MariaDB 10.1 releases to compatible format. This prevents a downgrade to earlier MariaDB 10.1 versions. See the commit for details.
