Installation	Installing Percona Server for MongoDB

Percona Server for MongoDB 5.0.13-12 is an enhanced, source-available, and highly-scalable database that is a fully-compatible, drop-in replacement for MongoDB 5.0.13 and MongoDB 5.0.13 Community Edition.

It supports protocols and drivers of both MongoDB 5.0.12 and 5.0.13.

This release of Percona Server for MongoDB includes the improvements and bug fixes of MongoDB Community Edition 5.0.12 and 5.0.13.

Release Highlights¶

Data at rest encryption using the KMIP protocol is now generally available, enabling you to use this functionality in production environments.
Percona Server for MongoDB Docker container now includes the mongodb-tools utility set to align with the upstream container. This enables users to manage backup/restore operations of Percona Server for MongoDB.
Updated exit code and status message during the master key rotation improves the user experience while using data-at-rest encryption with KMIP.
Fixed security vulnerability CVE-2022-3602 for Percona Server for MongoDB version 5.0.9-8 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-60958 - Prevent the server from hanging in chunk migration when a step-down occurs.
SERVER-65382 - Fixed the issue with incorrect chunk size comparison during split by preventing the AutoSplitVector from using the clientReadable.
SERVER-63843 - Fixed the logger deadlock by adding a check against recursive logging
WT-9870 - Fixed the global time window state before performing the rollback to stable operation by updating the pinned timestamp as part of the transaction setup.
SERVER-69220 - Fixed the issue that could lead to data inconsistency by introducing the additional validation of field types for shard key patterns. Users should not modify the type (hashed or range) for the existing shard key fields
SERVER-67650 - Fixed the issue with failing resharding operation by introducing the start and end time metrics for resharding recipient
SERVER-68094 - Fixed the projection error during the resharding operation by using the $replaceRoot stage instead of the $project one
