Vector annotations (beta)

Introducing two new tags: Vector and VectorLabels.

These tags open up a multitude of new uses cases from skeletons, to polylines, to Bézier curves, and more.

Set model provider API keys for an organization

There is a new Model Providers page available at the organization level where you can configure API keys to use with LLM tasks.

If you have previously set up model providers as part of your Prompts workflow, they are automatically included in the list.

For more information, see Model provider API keys for organizations.

Improved UX on the Organization page

The Organization page (only accessible to Owner and Admin roles) has been redesigned to be more consistent with the rest of the app.

Note that as part of this change, the Access Token page has been moved under Settings.

Hide Data Manager columns from users

There is a new project setting available from Annotation > Annotating Options and Review > Reviewing Options called Show unused data columns to reviewers in the Data Manager.

This setting allows you to hide unused Data Manager columns from any Annotator or Reviewer who also has permission to view the Data Manager.

"Unused" Data Manager columns are columns that contain data that is not being used in the labeling configuration.

For example, you may include meta or system data that you want to view as part of a project, but you don't necessarily want to expose that data to Annotators and Reviewers.

Find user IDs easier

Each user has a numeric ID that you can use in automated workflows. These IDs are now easier to quickly find through the UI.

You can find them listed on the Organization page and in the Annotation Summary table on the Members page for projects.

Manager and Reviewer access to the Annotator Dashboard

Managers and Reviewers will now see a link to the Annotator Dashboard from the Home page.

The Annotator Dashboard displays information about their annotation history.

Multiple SDK enhancements

We have continued to add new endpoints to our SDK, including new endpoints for bulk assign and unassign members to tasks.

See our SDK releases and API reference.

Bug fixes

Fixed an issue where the Info panel was showing conditional choices that were not relevant to the selected region.
Fixed an issue where on tasks with more than 10 annotators, the number of extra annotators displayed in the Data Manager column would not increment correctly.
Fixed an issue where if a project included predictions from models without a model name assigned, the Members dashboard would throw errors.
Fixed an issue where the workspaces dropdown from the Annotator Performance page will disappear if the workspace name were too long.
Fixed an issue with the disabled state style for the Taxonomy tag on Dark Mode.
Fixed an issue where long taxonomy labels would not wrap.
