Release Highlights

  • Support of multiple KMIP servers adds failover to your data-at-rest encryption setup.

  • Allow users to set KMIP client certificate password through a flag to simplify the migration from MongoDB Enterprise to Percona Server for MongoDB.

  • Percona Server for MongoDB is now available on Ubuntu 22.04 (Jammy Jellyfish).

  • SERVER-58506 - Extend the getParameter command output with the information about a parameter to be enabled on runtime or only on startup

  • SERVER-62272 - Ensure that applying schema validation rules to a non-empty collection prevents chunk migration for the data that existed before these rules were applied.

  • SERVER-66176 - Improve the CollectionCatalog workflow by making hashing before taking a lock and adding an API for restoring after yield.

  • SERVER-61097 - Fixed the issue with cache eviction causing deadlocks by allowing a transaction to time itself out
