Studio 3T 2025.9 provides a number of improvements and fixes to improve stability and usability.
We’ve improved the $merge stage aggregation behavior across our tools and ensured accurate document counts with collation.
Improvements in Studio 3T 2025.9
Other Improvements
In the Aggregation Editor and IntelliShell, the $merge stage no longer returns a result, making its behavior consistent with the MongoDB Shell.
Fixed in Studio 3T 2025.9
Collection Tab
Now takes collation options into account when counting the number of documents in a collection.
Imports
Fixed an application failure that could occur when clicking Import in the toolbar without any selection in the connection tree.
Other Fixes
You can now update Studio 3T from within the notification messages even when an NPS Survey notification is present.
For the full history of changes in Studio 3T, see the change log.
