[3.13.0] - 2024-04-03

New Features and Improvements

  • Benchmarks can now be fuzzy. For example, a project manager may mark more than one correct answer to a radio or dropdown classification. Read more in our docs.

  • In projects where benchmarking has been activated, the Tasks tab now shows each benchmark’s average score and the number of users who have annotated each benchmark.

  • Hiding or revealing objects with the keyboard shortcut “H” will no longer delete an annotation that is currently being drawn with the mouse cursor.

  • Answers to multiple classification questions no longer have a line running between the classification title and its options, improving readability in projects with large numbers of multiple classification answers.

  • The code powering the Segmentation tool has been substantially rewritten, leading to possible performance improvements in some scenarios and simplifying further development on the tool.

  • Idle duration and blur duration times can now be optionally included in the export.

  • The way total, idle, and blur durations are displayed in the Task Info panel has been improved.

Bug Fixes

  • Fixed a bug where the “Set as Sample” button was visible for users with the Labeler and Reviewer role.

  • Fixed a bug where the consensus scores shown int the Tasks tab and in the Stage History panel would occasionally mismatch.

[3.12.0] - 2024-03-14

New Features and Improvements

  • Introducing benchmarks, also known as test questions or gold sets. With benchmarks, project managers will be able to measure the performance of annotators by having them annotate against known good tasks. Read more in our docs here.

  • The consensus calculation algorithm has been rewritten, now providing more intuitive consensus score results. Consensus projects created before Ango Hub 3.11 are not affected. Read more in our docs

  • The way tasks leave a consensus stage (i.e. adjudication) has been changed. Before this update, the consensus judgment that was sent was the one that was submitted last. Now, the task output from a Consensus stage is a composite task, combining all of the best consensus answers. Read more in our docs.

  • Added storage integration support for Azure. Read more in our docs.

  • The way metadata (e.g. frame count, frame rate, duration) is extracted for video assets has been updated to be more reliable.

  • Tools and classifications can no longer have single letters as shortcuts for quick selection. Existing classes and classifications with single letters as their shortcut will no longer be selectable with their keyboard shortcut. This was done to free up possible keyboard shortcuts for other functionality in the editor.

  • The description of an object can now be quickly changed by pressing “D” when the object is selected.

  • Task-level issues can now be opened by pressing “I” when no object is selected.

  • Object-level issues can now be opened by pressing “I” when an object is selected.

  • The opening and closing smoothing types have been added to the medical labeling editor.

  • The medical brush tool can now be used within a threshold region you specify. Open the threshold tool while the brush is active and the brush will only paint in areas defined by the threshold.

Bug Fixes

  • Fixed a bug where Hub would not warn users of unsaved changes on exit if the only modification was a change in annotation layering.

  • Fixed a bug where disabling interpolation of a rich text classification in video tasks could lead to a crash.

  • Fixed a bug where disabling interpolation of a text classification in video tasks did not correctly reset the classification.

  • Fixed a bug where disabling interpolation of a tree dropdown classification in video tasks did not correctly reset the classification.

  • Fixed a visual bug where, in the Overview tab, the auto-forward status of the Start stage was not always reflected accurately.

  • Fixed a bug where, in rare cases, vertical videos would appear stretched horizontally in the video labeling editor.

[3.11.0] - 2024-02-13

New Features and Improvements

  • The message returned by the SDK when attempting to upload annotations for assets not in the Start stage has been improved for clarity.

  • Videos can now be scrubbed from the playback timeline while the video is playing.

Bug Fixes

  • Fixed a bug where the logic sanity validation would give a warning if, in the “Annotation Type” logic, the class name was empty

  • Fixed a bug where project managers who were not organization admins could not upload pre-labels.

  • Fixed a bug where, occasionally, NRRD files could not be saved if they had previously had overlapping annotations.

  • Fixed a bug where in the video editor annotation timeline, classifications may visually appear as relations.

  • Fixed a bug where exports of video tasks may contain duplicate annotations.
