Release notes


  • When you create a set of search filters in Catalog, the URL will update based on the search. This means you can easily share filtered view of Catalog with your team.
  • With the new asset proxy feature, security-conscious customers can restrict access to specific assets shared by labelers. Labelbox uses cookies to restrict access, ensuring that only authorized users can access specified links to assets and attachments.
  • In the editor, you can now use common undo & redo shortcuts when creating classifications. Visit this page to see a list of all available shortcuts.
  • The natural language search filter in Catalog now supports text assets. This means you can describe the data you are looking for with words and Labelbox will surface the corresponding text assets in Catalog.
  • Our new pricing model introduces three limits to the free and starter tiers: 30 users, 25 ontologies, 50 projects. Visit this page to view all platform limits.
