Label Studio Enterprise 2.22.0

Mar 25, 2025

Helm Chart version: 1.9.6

New features

Pause an annotator

There is a new action to pause annotators. This is available from the Members dashboard and via the API.

For more information, see Pause an annotator.

Annotation limits

There is a new Quality > Annotation Limit section in the project settings.

You can use these fields to set limits on how many tasks each user is able to annotate. Once the limit is reached, their progress will be paused.

For more information, see Annotation Limit.

Personal access tokens

There is a new type of token available for API access. The new tokens use JWT standards.

You can enable or disable these tokens from the Organization page. Once enabled, they will be available for users to generate from their Account & Settings page. Legacy tokens can still be used unless disabled from the organization level.

For more information, see Access tokens.

Deep link annotations and regions

You can now link directly to specific annotations or regions within an annotation. These actions are available from the labeling interface in the overflow menus for the annotation and the region.

Usability improvements for audio tasks

Scrollbar navigation

You can now scroll forward and backward within audio files. This can be activated using the scrolling motion on a trackpad or a mouse.
