Installation	Installing Percona Server for MongoDB

Percona Server for MongoDB 4.2.23-23 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 4.2.23 Community Edition. It supports MongoDB 4.2.23 protocols and drivers.

Release Highlights

• Data-at-rest encryption using the Key Management Interoperability Protocol (KMIP) is generally available enabling you to use it in your production environment

• $backupCursor and $backupCursorExtend aggregation stages functionality is generally available, enabling your application developers to use it for building custom backup solutions.

  Note

  Percona provides Percona Backup for MongoDB - the open source tool for consistent backups and restores in MongoDB sharded clusters.

• Fixed security vulnerability CVE-2022-3602 for Percona Server for MongoDB 4.2.21-21 and higher installed from tarballs on Ubuntu 22.04.

The bug fixes, provided by MongoDB and included in Percona Server for MongoDB, are the following:

• SERVER-68925 - Detect and resolve table logging inconsistencies for WiredTiger tables at startup

• SERVER-56127 - Fixed retryable writes on update and delete commands to not execute more than once if chunk is migrated and shard key pattern uses nested fields

• SERVER-66310 - Changed the ExpressionSetUnion::isCommutative() function to return false when a non-simple collation is in place for the $setUnion aggregation expression

• SERVER-68359 - Prevent TTLMonitor from processing index if expireAfterSeconds value is NaN (Not a Number)
