Warning

Due to critical issues identified in previous releases that may affect data integrity and performance, we recommend upgrading all production environments to the latest version - currently MongoDB 5.0.15. Find details about those issues in MongoDB 5.0 Community Edition release notes.

Release Highlights

  • The support for authentication using AWS IAM enables you to natively integrate Percona Server for MongoDB with AWS services, increase security of your infrastructure by setting up password-less authentication and offload your DBAs from managing different sets of secrets. This is the technical preview feature
  • Improved master key rotation for data at rest encrypted with HashiCorp Vault enables you to use the same secret key path on every server in your entire deployment thus significantly simplifying the secrets management and key rotation process.

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

  • SERVER-54900 - Fixed the issue with blocked networking calls preventing the oplog fetching process to re-establish the connection to an unresponsive sync-source node
  • SERVER-72416 - Fixed the issue with incorrect projection parsing when a collection level collation is specified
  • SERVER-71759 - Changed the yielding policy of dataSize command to YIELD_AUTO for both when the command is called with estimate:true or false
  • SERVER-72535 - Disallow creating the ‘admin’, ‘local’, and ‘config’ databases with alternative cases in names on sharded clusters
  • SERVER-72222 - Fixed the incorrect behavior of the mapReduce command with single reduce optimization in sharded clusters
  • WT-9926 - Fixed a crash during startup from backup can lose metadata by not deleting checkpoints during recovery from backup
  • WT-9751 - Fixed a memory leak in reconciliation after aborted eviction
  • SERVER-72222 - Fixed mapReduce with single reduce optimization from failing in sharded clusters
  • SERVER-71399 - Fixed the issue with not removing the jumbo flag upon successful split of the chunk
  • SERVER-71191 - Fixed the deadlock between index build setup, prepared transaction and stepdown by unlocking and relocking Replication State Transition Lock (RSTL) during index build setup
