Release Highlights

This release of Percona Distribution for MongoDB includes bug fixes and improvements provided by MongoDB and included in Percona Server for MongoDB 5.0.13-11. Among them are the following:

  • Data at rest encryption using the KMIP protocol is now generally available, enabling you to use this functionality in production environments.

  • Fixed security vulnerability CVE-2022-3602 for Percona Distribution for MongoDB 5.0.8 and higher installed from tarballs on Ubuntu 22.04.

  • Updated exit code and status message during the master key rotation improves the user experience while using data-at-rest encryption with KMIP.

  • Detected and resolved table logging inconsistencies for WiredTiger tables at startup

  • Prevented the server from hanging in chunk migration when a step-down occurs.

  • Fixed the issue with incorrect chunk size comparison during split by preventing the AutoSplitVector from using the clientReadable.

  • Fixed the logger deadlock by adding a check against recursive logging

  • Fixed the global time window state before performing the rollback to stable operation by updating the pinned timestamp as part of the transaction setup.

  • 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

  • Fixed the issue with failing resharding operation by introducing the start and end time metrics for resharding recipient

Percona Backup for MongoDB 2.0.1 improvements include the following:

* The ability to [define a timezone for logs and to follow the logs dynamically](
