Changelog

February 11, 2026

Project and task states

Project and tasks will have states depending on the actions you have taken on them and where they are in the workflow.

State management is currently being rolled out so that we can backfill tasks and projects created before this feature was implemented. If you do not see it yet, you will in the coming days.

Set strict overlap for annotators

There is a new Enforce strict overlap limit setting under Quality > Overlap of Annotations.

Previously, it was possible to have more annotations than the number you set for Annotations per task.

This would most frequently happen in situations where you set a low task reservation time, meaning that task locks expired before annotators submitted their tasks -- allowing other annotators to access and then submit the task, and potentially resulting in an excess of annotations.

When this new setting is enabled, if too many annotators are try to submit a task, they will see an error message. Their draft will be saved, but they will be unable to submit their annotation.

Note that strict enforcement only applies towards annotations created by users in the Annotator role.

Configure continuous annotator evaluation

Previously, when configuring annotator evaluation against ground truth tasks, you could configure exactly how many ground truth tasks each annotator should see as they begin annotating. The remaining ground truth tasks would be shown to each annotator depending on where they are and the task ordering method.

Now, you can set a specific number of ground truth tasks to be included in continuous evaluation.

You can use this as a way to ensure that not all annotators see the same ground truths, as some will see certain tasks during continuous evaluation and others will not.

Before:

After:

Increased limit for overlap

You can now set annotation overlap up to 500 annotations. Previously this was restricted to 20 when setting it through the UI.

Press Ctrl + F to search the Code tab

When working in the template builder, you can now use Ctrl + F to search the your labeling configuration XML.

Restrict Prompts evaluation for tasks without predictions

There is a new option to only run a Prompt against tasks that do not already have predictions.

This is useful for when you have failed tasks or want to target newly added tasks.

Deprecated GPT models for Prompts

The following models have been deprecated:

gpt-4.5-preview gpt-4.1 gpt-4.1-mini gpt-4.1-nano gpt-4 gpt-4-turbo gpt-4o gpt-4o-mini o3-mini o1

Updated project Members page

The Project > Settings > Members page has been fully redesigned.

It includes the following changes:

Now, when you open the page, you will see a table with all project members, their role, when they were last active, and when they were added to your organization.
You can now hide inherited project members.

Inherited members are members who have access to the project because they inherited it by being an Administrator or Owner, or by being added as a member to the project's parent workspace.
To add members, you can now click Add Members to open a modal where you can filter organization members by name, email, and last active.

Depending on your organization's permissions, you can also invite new organizations members directly to the project.

Before

After

Members page:

Add Members modal:

Updated members table on Organization page

The members table on the Organization page has been redesigned and improved to include:

A Date Added column
Pagination and the ability to select how many members appear on each page
When viewing a member's details, you can now click to copy their email address

Members table:

Member details:

Service Principal authentication for Databricks

When setting up cloud storage for Databricks, you can now select whether you want to use a personal access token, Databricks Service Principal, or Azure AD Databricks Service Principal.

Easier multi-user select in the Member Performance dashboard

When you want to select multiple users in the Member Performance dashboard, there is a new All Members option in members drop-down.

If you are filtering the member list, All Members will select all users matching your search criteria (up to 50 users).
If you are not filtering the member list, All Members will select the first 50 users.

Unpublish projects when moving to the Personal Sandbox

If you have a published project that is in a shared workspace and you move it to your Personal Sandbox workspace, the project will automatically revert to an unpublished state.

Note that published projects in Personal Sandboxes were never visible to other users. This change is simply to support upcoming enhancements to project work states.

Upcoming changes for custom weights

In preparation for upcoming enhancements to agreements, we are deprecating some functionality.

In addition to the changes outlined here, we will be changing how custom weights work for class-based control tags.

Class-based control tags are tags in which you can assign individual classes to objects.

These include:

All Label-type tags (<Labels>, <RectangleLabels>, <PolygonLabels>, etc.)
<Choices>
<Pairwise>
<Rating>
<Taxonomy>

Instead of being able to set a percentage-based weight for each individual class, you will soon only be able to include or exclude them from calculation by turning them on or off.

For any existing projects that have custom class weights, the class weight will change to 100% weight.

You can still set a percentage-based weight for the parent control tag (<Labels> in the screenshot below).

Bug fixes

Fixed an issue where extra space appeared at the end of Data Manager table rows.
Fixed an issue where virtual/temporary tabs in the Data Manager appeared solid when viewed in Dark Mode.
Fixed an issue where emailed invite links for Organizations were expiring within 24 hours.

January 21, 2026

Fixed an issue where API token creation was not generating activity log entries.
Fixed an issue with cloud storage job failures caused by synchronization issues related to large JSON files.
Fixed several issues with timeouts related to bulk labeling.

January 14, 2026

Programmable interfaces with React

We're introducing a new tag: <ReactCode>.

ReactCode represents new evaluation and annotation engine for building fully programmable interfaces that better fit complex, real-world labeling and evaluation use cases.

With this tag, you can:

Build flexible interfaces for complex, multimodal data
Embed labeling and evaluation directly into your own applications, so human feedback happens where your experts already work
Maintain compatibility with the quality, governance, and workflow controls you use in Label Studio Enterprise

For more information, see the following resources:

Standardized time display format across the app

How time is displayed across the app has been standardized to use the following format:

[n]h [n]m [n]s

For example: 10h 5m 22s

Bug fixes

Fixed a layout issue with the overflow menu on the project Dashboard page.
Fixed a small UI issue in Firefox related to horizontal scrolling.
Fixed an issue that prevented the project dashboard CSV and JSON exports from working.
Fixed an issue with the organization members page where clicking on a member would reset the table pagination.
Fixed an issue causing the annotation time in the Member Performance dashboard to not evaluate correctly.

January 7, 2026

Use Shift to select multiple Data Manager rows

You can now select a Data Manager row, and then while holding shift, select another Data Manager row to select all rows between your selections.

Added support for latest Anthropic models

Added support for the following models:

claude-sonnet-4-5
claude-haiku-4-5
claude-opus-4-5

To better utilize space, the annotation ID and the navigation controls for the labeling stream have been moved to below the labeling interface.

Upcoming changes to agreements

In preparation for upcoming enhancements to agreements, we are deprecating some functionality.

In the coming weeks, we will be changing how we support the following features:

The following agreement metrics for bounding boxes, brushes and polygons will be removed:
- F1 score at specific IOU threshold
- Recall at specific IOU threshold
- Precision at specific IOU threshold
Any existing projects that use the agreement metrics listed above will change to a standard IoU calculation.
There will be additional updates for custom label weights. See the January 28th changelog for details.

Reach out to your CSM or Support if you have any questions and would like help preparing for the transition.

Bug fixes

Fixed an issue where the Copy region link action from the overflow menu for a region disappeared on hover.
Fixed an issue with prediction validation for the Ranker tag.
Fixed an issue where import jobs through the API could fail silently.
Fixed an issue with how the Enterprise tag appeared on templates when creating a project.
Fixed an issue where the workspace Members action was not always clickable.

December 17, 2025

Annotator evaluation enhancements

The Annotator Evaluation feature been improved to include a more robust ongoing evaluation functionality and improved clarity within the UI.

Enhancements include:

An improved UI to make it clearer what will happen based on your selections.
Previously if you were using "ongoing" evaluation mode, ground truth tasks were restricted by whatever overlap you configured for your project. This meant that typically only the first annotators to reach the ground truth tasks were evaluated.

Now, if annotator evaluation is enabled, all annotators will be evaluated against ground truth tasks regardless of whether the overlap threshold has been reached. This will ensure that even if the project has a large number of annotators and a comparatively small annotation-per-task requirement, all annotators will still be evaluated.
You can now set up your project so that annotator evaluation happens both at the beginning of the project as well as on an ongoing basis. Previously, you could only choose one or the other.

Before:

After:

Tip: You can disallow skipping in all project tasks. But if you want to allow skipping while ensuring that annotators cannot skip ground truth tasks, you can use the unskippable tasks feature recently introduced.

Find recent projects from the Home page

The Recent Projects list on the Home page will now include the most recently visited projects at the top of the list instead of pinned projects.

New Allow Skip column

To provide visibility to unskippable tasks, there is a new Allow Skip column in the Data Manager.

This column is filterable, hidden by default, and is only visible to Managers, Admins, and Owners.

Support for GPT-5.2

When you add OpenAI models to Prompts or to the organization model provider list, GPT-5.2 will now be included.

Bug fixes

Fixed an issue where header rows on the Permissions page were not sticky.
Fixed a styling issue when navigating back from the Activity Log page into the Members dashboard.
Fixed an issue where embedded YouTube videos were not working in <HyperText> tags.
Fix an issue with <DateTime> tags when using consensus-based agreement.

December 10, 2025

Command palette for enhanced searching

The command palette is an enhanced search tool that you can use to navigate to resources both inside and outside the app, find workspaces and projects, and (if used within a project) navigate to project settings.

For more information, see Command palette.

Unskippable tasks

While you can hide the Skip action in the project settings, this enhancement allows you to configure individual tasks so that any user in the Annotator or Reviewer role should not be able to skip them.

To make a task unskippable, you must specify "allow_skip": false as part of the JSON task definition that you import to your project.

For example, the following JSON snippet would result in one skippable task and one unskippable task:

[
  {
    "data": {
      "text": "Demo text 1"
    },
    "allow_skip": false
  },
  {
    "data": {
      "text": "Demo text 2"
    }
  }
]

For more information, see Skipping tasks.

Apply overlap only to distinct users

When configuring Annotations per task for a project, only annotations from distinct users will count towards task overlap.

Previously, if a project had Annotations per task set to 2, and User A created and then submitted two annotations on a single task (which can be done in Quick View), then the task would be considered completed.

Now, the task would not be completed until a different user submitted an annotation.

Bug fixes

Fixed an issue where accepted reviews were not reflected in the Members dashboard.
Fixed an issue where Submit and Skip buttons were hidden if opening the labeling stream when previously viewing the Task Summary.
Fixed an issue where PDFs could sometimes appear flipped.

December 3, 2025

The Member Performance dashboard has been moved to a location under Analytics in the navigation menu. This page now also features an improved UI and more robust information about annotating and reviewing activities, including:

Consolidated and streamlined data
Additional per-user metrics about reviewing and annotating activity
Clearer UI guidance through tooltips
Easier access through a new Analytics option in the navigation menu

For more information, see Member Performance Dashboard.

Presets when setting up SAML

When configuring SAML, you can now click on a selection of common IdPs to pre-fill values with presets.

Bug fixes

Fixed an issue where region labels were not appearing on PDFs even if the Show region labels setting was enabled.
Fixed an issue where PDFs were not filling the full height of the canvas.
Fixed a minor visual issue when auto-labeling tasks in Safari.
Fixed an issue where clicking on an annotator's name in the task summary did not lead to the associated annotation.

November 26, 2025

Improved annotation tabs

Annotation tabs have the following improvements:

To improve readability, removed the annotation ID from the tab and truncated long model or prompts project names.
Added three new options to the overflow menu for the annotation tab:
- Copy Annotation ID - To copy the annotation ID that previously appeared in the tab
- Open Performance Dashboard - Open the Member Performance Dashboard with the user and project pre-selected.
- Show Other Annotations - Open the task summary view.

Fixed an issue that prevented scrolling the filter column drop-down after clear a previous search.

November 19, 2025

Task summary improvements

We have made a number of improvements to task summaries.

Before:

After:

Improvements include:

Label Distribution

A new Distribution row provides aggregate information. Depending on the tag type, this could be an average, a count, or other distribution.
Updated styling

Multiple UI elements have been updated and improved, including banded rows and sticky columns. You can also now see full usernames.
Autoselect the comparison view

If you are looking at the comparison view and move to the next task, the comparison view will be automatically selected.

Agreement calculation change

When calculating agreement, control tags that are not populated in each annotation will now count as agreement.

Previously, agreement only considered control tags that were present in the annotation results. Going forward, all visible control tags in the labeling configuration are taken into consideration.

For example, the following result set would previously be considered 0% agreement between the two annotators, as only choices group 1 would be included in the agreement calculation.

Now it would be considered 50% agreement (choices group 1 has 0% agreement, and choices group 2 has 100% agreement).

Annotator 1

Choices group 1

A ✅
B ⬜️

Choices group 2

X ⬜️
Y ⬜️

Annotator 2

Choices group 1

A ⬜️
B ✅

Choices group 2

X ⬜️
Y ⬜️

Notes:

This change only applies to new projects created after November 13th, 2025.

Only visible tags are taken into consideration. For example, you may have tags that are conditional and hidden unless certain other tags are selected. These are not included in agreement calculations as long as they remain hidden.

Support for GPT-5.1

When you add OpenAI models to Prompts or to the organization model provider list, GPT-5.1 will now be included.

Bug fixes

Fixed an issue where the full list of compatible projects was not being shown when creating a new prompt.
Fixed an issue with the drop-down height when selecting columns in Data Manager filters.
Fixed an issue in the agreement matrix on the Members dashboard in which clicking links would open the Data Manager with incorrect filters set.
Fixed an issue in which long URLs would cause errors.
Fixed an issue with the Agreement (Selected) column in which scores were lower than expected in some cases.
Fixed an issue where low agreement strategies failed to execute properly if the threshold was set to 99%.

November 12, 2025

October 29, 2025

New Agreement (Selected) column

There is a new Agreement (Selected) column that allows you to view agreement data between selected annotators, models, and ground truths.

This is different than the Agreement column, which displays the average agreement score between all annotators.

Also note that now when you click on a comparison between annotators in the agreement matrix, you will be taken to the Data Manager with the Agreement (Selected) column pre-filtered for those annotators and/or models.

October 8, 2025

New Markdown tag

There is a new <Markdown> tag, which you can use to add content to your labeling interface.

For example, adding the following to your labeling interface:

<View>
<Markdown>
## Heading 2
    
### Heading 3
    
- bullet point one
- bullet point two
    
**Bold text** and *italic text*
    
`inline code`

```
    
[Link](https://humansignal.com/changelog/)

![image](https://upload.wikimedia.org/wikipedia/commons/2/27/Opossum_2.jpg)
</Markdown>
</View>

Produces this:

JSON array input for the Table tag

Previously, the Table tag only accepted key/value pairs, for example:

{
  "data": {
    "table_data": {
      "user": "123456",
      "nick_name": "Max Attack",
      "first": "Max",
      "last": "Opossom"
    }
  }
}

It will now accept an array of objects as well as arrays of primitives/mixed values. For example:

{
  "data": {
    "table_data": [
      { "id": 1, "name": "Alice", "score": 87.5, "active": "true" },
      { "id": 2, "name": "Bob",  "score": 92.0, "active": "false" },
      { "id": 3, "name": "Cara", "score": null, "active": "true" }
    ]
  }
}

Create regions in PDF files

You can now perform page-level annotation on PDF files, such as for OCR, NER, and more.

This new functionality also supports displaying PDFs natively within the labeling interface, allowing you to zoom and rotate pages as needed.

The PDF functionality is now available for all Label Studio Enterprise customers. Contact sales to request a trial.

New parameters for the Video tag

The Video tag now has the following optional parameters:

defaultPlaybackSpeed - The default playback speed when the video is loaded.
minPlaybackSpeed - The minimum allowed playback speed.

The default value for both parameters is 1.
