New Features in v4.8.6
This release introduces several key new capabilities for self-hosted FastGPT deployments:
- App permission inheritance: Added support for inheriting access permissions across linked application workflows.
- Individual dataset collection disabling: Administrators can now disable specific collections within a dataset, rather than only toggling the entire dataset's availability.
- Updated system plugin architecture: Launched two official built-in plugins: Link Reader and Math Calculator. Official documentation for creating custom system plugins will be publicly released alongside this update.
- Code sandbox runtime parameters: New configurable runtime parameters for isolated code execution sandboxes.
- Mobile-optimized header toggle: Added an optional setting to hide the conversation interface header, optimized for mobile device viewing experiences.
Performance and Stability Enhancements
Several improvements were made to reduce resource load and improve system reliability:
- Database load optimization: File reading operations now default to connecting to MongoDB secondary nodes, reducing unnecessary operational load on the primary database instance.
- Redundant resource fix: Resolved an issue where MongoDB models were loaded multiple times during runtime, cutting down on redundant memory and CPU usage.
- Prompt template improvements: Updated core prompt template functionality to resolve consistent edge-case behavior during template rendering.
