Notable changes

Starting in this version, when you add an ML backend, a webhook is created to send an event to your ML backend each time an annotation is updated or created. Alongside this change, the following has also changed:

  • The completions parameter of the fit() method is deprecated and will be removed in the next release.
  • "Start model training after any annotations are submitted or updated" is now unchecked by default.
  • Requests to the /train API endpoint now include a timeout.

See train a model with your ML backend for more details about this change.

  • Fixed issues with permissions when setting up local file storage connections.
  • Fixed issues with building and installing Label Studio taking a long time due to resolving various google dependencies.
  • Fixed an issue where the selected=true option for the Choices tag wasn't being used. Thanks to @DougTrajano for reporting in issue #1848.
  • Fixed issue #1757 reported by @uriel-tannen that prevented saving a labeling configuration without existing labels.
