Percona Server for MySQL 8.0.13-4

Percona announces the release of Percona Server for MySQL 8.0.13-4 on January 17, 2019 (downloads are available here and from the Percona Software Repositories). This release contains a fix for a critical bug that prevented Percona Server for MySQL 5.7.24-26 from being upgraded to version 8.0.13-3 if there were more than around 1000 tables, or if the maximum allocated InnoDB table ID was around 1000. Percona Server for MySQL 8.0.13-4 is now the current GA release in the 8.0 series. All of Percona’s software is open-source and free.

Percona Server for MySQL 8.0 includes all the features available in MySQL 8.0 Community Edition in addition to enterprise-grade features developed by Percona. For a list of highlighted features from both MySQL 8.0 and Percona Server for MySQL 8.0, please see the GA release announcement.
