  • Restrict sample email sending to users with Cluster Admin or Workspace Admin role.

  • Restricted list users and list groups endpoints to users with project management permissions (Cluster Admins and Cluster Users).

  • List users and list groups access extended to Project Admins.

Known Issues#

  • In specific scenarios, cross-lingual information retrieval for semantic search may deliver lower-than-expected quality (SQ-28171).

Breaking Changes#

  • Introduction of nutrient_pdf_viewer.license_key configuration to frontend.ini, required for PDF viewing to work properly.

  • The migrated PDF viewer requires additional Content Security Policy directives. Add the following to security.content-security-policy in the server configuration:

    worker-src blob:
img-src blob:
script-src 'wasm-unsafe-eval'

    The PDF viewer does not load without those directives.quest
