Amazon DocumentDB now supports engine minor version starting with 5.0.1

Amazon Web Services has released engine minor version 5.0.1 for Amazon DocumentDB, its MongoDB-compatible managed database service. The update introduces enhanced aggregation capabilities with new operators including $rand, $pow, $dateToParts, and $dateFromParts, while adding an active connections metric for instance monitoring and granular command-level performance metrics in CloudWatch that track specific operations like find, insert, findAndModify, and update commands. The minor version release represents AWS's shift toward providing more granular control over database upgrades, allowing customers to specify when and how they upgrade their DocumentDB clusters. Users can deploy the new version when creating clusters or manually upgrade existing 5.0.0 clusters through the AWS Management Console or CLI, though upgrades are irreversible and moving from the long-term support (LTS) 5.0.0 track to 5.0.1 means losing LTS status. The update is available across all AWS regions where DocumentDB 5.0 is supported.
