Percona Server for MongoDB 4.0.14-8

Percona announces the release of Percona Server for MongoDB 4.0.14-8 on January 9, 2020. Download the latest version from the Percona website or the Percona software repositories.

Percona Server for MongoDB is an enhanced, open source, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.0 Community Edition. It supports MongoDB 4.0 protocols and drivers.

Percona Server for MongoDB extends the functionality of the MongoDB 4.0 Community Edition by including the Percona Memory Engine storage engine, encrypted WiredTiger storage engine, audit logging, External LDAP Authentication with SASL, hot backups, and enhanced query profiling. Percona Server for MongoDB requires no changes to MongoDB applications or code.

This release includes all features of MongoDB 4.0 Community Edition. Most notable among these are:

• Multi-Document ACID transactions

• Type conversion through the new aggregation operators

• Enhancements to the Change Streams support

Note that the MMAPv1 storage engine is deprecated in MongoDB 4.0 Community Edition.

Percona Server for MongoDB 4.0.14-8 is based on MongoDB 4.0.14.

Bugs Fixed

• PSMDB-473: The logApplicationMessage 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 as clusterManager or hostManager.

  > db.runCommand({logApplicationMessage: 'find'});
