# 6.139.0

November 20, 2025

## **What's New? 💡**

### **Data Studio**

* Search Extension in Span Labeling — Updated the “Label all” behavior to correctly follow the “Span should have at most one label” setting.
  * When multiple labels are allowed, the action now adds a new label to each span.
  * When only one label is allowed, it applies the label while replacing any existing one.
* Span Labeling arrow — Improved arrow rendering for label-to-label connections within the same span, making the relationships clearer and easier to follow.
* Comments — Removed the comment button from the app bar, as the comment feature is now fully supported through the [Comment extension](https://docs.datasaur.ai/advanced/extensions/comments).
* Row Labeling — Improved the error message shown when deleting the only question, ensuring a clear message that guides users on what to do next.

## **Bug Fixes 🐞**

### **Data Studio**

* Fixed an issue in Span Labeling where pre-labeled labels did not appear in the editor when the pre-labeled file contained labels that were also included in the label set configured during project creation.
* Fixed an issue where quickly switching between projects or rapidly switching between Reviewer and Labeler modes could trigger “429 too many requests” errors.
* Fixed an issue in Custom Report Builder and Activity where the team member filter doesn't work properly with a substring value of a member's name.
* Fixed the evaluation metrics calculation, mainly due to inaccuracy in confusion matrix.
