Label Studio 1.6 Release Notes

The Label Studio 1.6 open source release now supports video object tracking in general availability, making it the most popular open source data labeling platform to support all data types—video, image, text and hypertext, time series, and audio. In addition to the new video player that supports frame-by-frame video object tracking, the latest release also features a new annotation user interface called the Outliner that is more efficient, ergonomic, and flexible.
