Light - Use light mode.
Dark - Use dark mode.

!!! note Dark mode is not available for environments that use white labeling.

New Label Studio Home page

When you open Label Studio, you will see a new Home page. Here you can find links to your most recent projects, shortcuts to common actions, and links to frequently used resources

!!! note The home page is not available for environments using whitelabeling.

Annotator Evaluation settings

There is a new Annotator Evaluation section under Settings > Quality.

When there are ground truth annotations within the project, an annotator will be paused if their ground truth agreement falls below a certain threshold.

For more information, see Annotator Evaluation.

New Insert Plugins menu and Testing interface

There are a number of new features and changes related to plugins:

There is a new Insert Plugins menu available. From here you can insert a pre-built plugin that you can customize as necessary.
When you add a plugin, you will see a new Testing panel below the plugin editing field. You can use this to verify what events are triggered, manually trigger events, and modify the sample data as necessary.
To accompany the new Insert Plugins menu, there is a new Plugins gallery in the documentation that discusses each option and has information on creating your own custom plugs.
There is also a new setting that allows you to restrict access to the Plugins tab to Administrator users. By default, it is also available to Managers. This can be set through the Django admin panel.

Export underlying data from the Annotator Performance dashboard

There is a new Export Underlying Data action for the Annotations chart.

Annotators can now view their own performance dashboard metrics

When logging in, annotators will now see a link to the Annotator performance dashboard, where they can see their own performance metrics.

Improved drop-down selectors

When there are a large number of options in a drop-down menu, you can now search through the list of available options.

Label Studio Converter CLI

When you install the Label Studio SDK, you can now use the label-studio-converter command from your terminal.

Miscellaneous

Performance enhancements around how membership API requests are made.
Added a new API call to rotate JWT tokens: POST api/token/rotate

Security

Addressed a CSP issue by removing unsafe-eval usage.
Added a rule that password resets will be limited to 5 per hour.
Upgraded Babel to address vulnerabilities.
Improved security on CSV exports.
Removed an unused endpoint.
By default, CORS is permissive. However, you can now set an environment variable to ensure it is in strict mode. Set one of the following:
- CORS_ALLOWED_ORIGINS
  A comma-separated list of Origin header values the Label Studio server will receive, e.g. https://example.org,https://example.net
- CORS_ALLOWED_ORIGIN_REGEXES
  Same as above, except using regex.
- CORS_ALLOW_ALL_ORIGINS
  Set to false or 0 to reject all Origin header values (that is, allow no cross-origin requests). By default this is set to true.
