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.
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.
