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.
