Percona Server for MySQL 5.7.29-32 was released on February 5, 2020. It is a free, fully compatible, enhanced and open source drop-in replacement for any MySQL database. This version includes several bug fixes, including PS-1469 where the Memory storage engine detected an incorrect “is full” condition, PS-5813 when setting the slow_query_log_use_global_control to “none” could cause an error, and PS-6123, when a Debian/Ubuntu init script used an incorrect comparison which could cause the service command to return before the server start.

ProxySQL 1.4.16 and Updated proxysql-admin Tool

On February 11, 2020, we announced that ProxySQL 1.4.16, released by ProxySQL, is available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool. ProxySQL is a high-performance proxy, currently for MySQL and database servers in the MySQL ecosystem (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. In this version, bug PSQLADM-219 was fixed, where the scheduler was handling the pxc_maint_mode variable incorrectly and open connections were closed immediately. Now the scheduler only sets the node status to OFFLINE_SOFT.


Percona Server for MongoDB 3.6.17-4.0

February 13, 2020, saw the release of Percona Server for MongoDB 3.6.17-4.0.  Based on MongoDB 3.6.17, this release fixed bug PSMDB-473 where thelogApplicationMessage command failed even when it was run by the user with extended privileges. The problem has been fixed to allow running the logApplicationMessage command by any role that has the applicationMessage privilege, such asclusterManager or hostManager.
