It supports protocols and drivers of MongoDB 4.4.28.

Release Highlights

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

  • SERVER-77506 - Fixed the issue with the data and the ShardVersion mismatch for sharded multi-document transactions by adding the check that no chunk has moved for the collection being referenced since transaction started
  • SERVER-82365 - Improved cluster balancer performance by optimizing the construction of the balancer’s collection distribution status histogram
  • SERVER-82883 - Fixed the issue with blocking acquiring read/write tickets by TransactionCoordinator by validating that it can be recovered on step-up and can commit the transaction when there are no storage tickets available
  • WT-7929 - Investigated a solution to avoid a Full Time Diagnostic Data Capture (FTDC) mechanism to stall during checkpoint
