# XtraDB option --innodb-release-locks-early

The --innodb-release-locks-early feature ([MWL#163](https://askmonty.org/worklog/?tid=163)) was included in the [5.2\
replication preview](https://mariadb.com/docs/server/ha-and-performance/standard-replication/obsolete-replication-information/mariadb-52-replication-feature-preview). However, it was omitted from [MariaDB 5.3](https://app.gitbook.com/s/aEnK0ZXmUbJzqQrTjFyb/community-server/old-releases/5.3/changes-improvements-in-mariadb-5-3) due to the bug [lp:798213](https://bugs.launchpad.net/maria/+bug/798213).
