What's New

Enhancements

  • The Keypoint, KeyPointLabels, Polygon, and PolygonLabels tags all support a new snap parameter for use in Image Segmentation labeling. When snap="pixel" is enabled, the (x, y) coordinates of each point are rounded to the pixel size. This enhancement will help ensure precise and uniform coordinates within images. For polygons, points are snapped to the pixel edge. For example, given a polygon point with the coordinates (0.25, 0.25), your resultant coordinates would snap to the edge of the pixel at (0,0). For keypoints, points are snapped to the pixel center. For example, given a keypoint with the coordinates (0.25, 0.25), your resultant coordinates would snap to the center of the pixel at (0.5,0.5). (#4682)

  • When reviewing video in Outliner, if you click on a marked region, the video playback will automatically jump to the selected region. Previously, users had to manually scroll to the starting point. This change will make it easier to quickly view and edit video segments. (#4797)

Bug Fixes

  • Fixed an issue where pressing Ctrl + or Ctrl - (Windows) or Cmd + or Cmd - (Mac) was not zooming in/out on images as expected. (#4784)

  • Fixed an issue where the number of drafts displayed in the project summary was not updated when drafts were submitted as annotations. (#4772)

  • Fixed and issue where, in certain contexts, labeling instructions were displayed in raw HTML. (#4779)

  • Fixed an issue that would cause a blank draft to be created when using hot-keyed annotation submit. (#4834)

  • Fixed an issue that occurred after project creation in which users were prevented from moving forward if changes were made in the template preview. (#4835)

  • Fixed an issue where users were unable to navigate through their task list after saving a draft. (#4823)

  • Fixed several issues with how annotation drafts were handled. Users will now see a more descriptive error message when trying to update a labeling configuration that is still being used in annotations or in drafts. Also, when using the Data Manager to delete all annotations, this will also delete all task drafts and annotation drafts. (#4802)

  • Fixed drf-yasg dependency issue that was blocking our ability to publish Label Studio to PyPi. (#4837)

  • Fixed an issue where blank drafts were being created when annotations were submitted. (#4796)

Enhancements

  • Added server-side encryption for target storage. (#4180)
  • Deactivated user pages will now include contact information. (#4637)
  • Removed unnecessary queries to improve performance in POST /api/tasks/ID/annotations. (#4608)
  • Improved performance of prediction counter calculations, leading to faster response times for project pages and stats calculations. (#4629)

  • Fixed an issue with feature flags so that they are now tied to user emails. (#4647)
  • Fixed an issue in which a feature flag was improperly hard-coded. (#4704)

Label Studio 1.7.2 Release Notes

The Label Studio 1.7.2 Open Source release introduces a new Magic Wand tool for image annotation and significant updates to our audio labeling functionality.

New Feature and Enhancement

Label Studio 1.7.2 includes the following new features and enhancements.

  • Added Magic Wand tool for image segmentation
    • This new community-contributed feature makes it possible to click in a region of an image for segmentation labeling, drag the mouse to dynamically change flood filling tolerance, then release the mouse button to get a new labeled area. The tool allows you to easily zoom for fine-grained detail and scan the zoomed-in image while still remaining highly performant.
  • Support simultaneous render of multi-channel audio with added splitchannels="true" option on Audio config (larger memory requirement)
    • This new feature allows users to visually separate each channel of a multichannel audio recording. This makes labeling overlapping audio segments (such as multiple people talking at same time) visually and functionally easier to annotate.
  • Improved rendering performance for large-duration audio, LSDV-3082
    • We’ve made improvements to the audio labeling interface that allows you to load and annotate audio files up to 5 hours in duration.
