What's New

Upgrade from DSPy-centric 3.4.0 to 4.17.1 with merged admin features and file-level permissions

Breaking Changes

  • Old admin paths (/admin/settings/*) are no longer retained; use new paths.
  • RLM interpreter API changes (keyword-only interpreter_factory) from underlying DSPy 3.4.0.
  • File permission switch is off by default; enabling it changes behavior for existing knowledge bases.

New Features

  • Commercial admin features merged into the main application.
  • File-level permissions for knowledge bases with inheritance and ownership transfer.
  • System model health monitoring with 48-hour visualization and Webhook alerts.
  • Batch operations support for Apps, Agents, and Skills.
  • Token statistics dashboard for apps.

Improvements

  • Automated migration scripts for data updates and cleanup.
  • Agent V2 citations display actual retrieved content in chat.
  • Unified password change flow supporting third-party authentication.

Bug Fixes

  • Fixes for workflows, tools, and document parsing.
  • Fixes for resource permission calculations in collaborative apps.

Upgrade Notes

Update Docker image tags to v4.17.1 and run automated migration scripts which do not block service startup. Update health check paths to /api/health if using Pro, and migrate to new admin paths (/admin/settings/*).
