title: Why MariaDB 10.2 uses again InnoDB instead of Percona XtraDB?
body: <p>MariaDB homepage says that they use Percona XtraDB until 10.1 and from 10.2 on they are going to use normal InnoDB again (<a href="https://mariadb.com/kb/en/mariadb/xtradb-and-innodb/" rel="nofollow noreferrer">https://mariadb.com/kb/en/mariadb/xtradb-and-innodb/</a>).</p>
  
  <p>This does not seem reasonable to me, because XtraDB seems to be the better / improved version of InnoDB (<a href="https://www.percona.com/software/mysql-database/percona-server/feature-comparison" rel="nofollow noreferrer">https://www.percona.com/software/mysql-database/percona-server/feature-comparison</a>). So is this a typo, are there any legal issues, or is the new version of InnoDB simply better than XtraDB?</p>
  
  <p>There is even a question on MariaDB page, but it has not been answered for weeks now.</p>
  
  <p>Sry, could not append all related links because of Stackoverflow rules.</p>
