FastGPT v4818 Upgrade Feature and Fix Summary

New Functional Additions

This release introduces five core new capabilities for self-hosted and commercial FastGPT deployments:

  1. Direct application creation via JSON configuration: Users can build FastGPT applications using JSON configuration files instead of the standard visual UI workflow.
  2. Rapid HTTP plugin creation via CURL scripts: The platform now supports generating HTTP plugins quickly using pre-written CURL scripts, reducing setup time for custom integrations.
  3. Department-based permission structure (Commercial edition): Commercial tier deployments gain access to a hierarchical departmental access control system for granular permission management.
  4. Custom CORS security policies: Administrators can configure custom cross-origin resource sharing rules. The default policy allows fully open access, with the following default settings:
Configuration SettingDefault Value
Allowed Origins*
Permitted HTTP MethodsAll
Permitted Request HeadersAll
  1. Private deployment model troubleshooting documentation: Official troubleshooting guides are now available for self-hosted private FastGPT model deployments.

System and Security Improvements

Twelve operational and security enhancements were implemented to improve reliability and user experience:

  • Enhanced HTTP body parsing to resolve newline handling issues in string variables
  • Updated share links to generate random user avatars for improved visual consistency
  • Strengthened image upload security validation, including unique avatar image storage to prevent cumulative storage bloat
  • Separated MongoDB full-text index tables to optimize database query performance
  • Merged dataset search queries to reduce unnecessary database calls
  • Improved CSV file encoding detection to reduce garbled text in uploaded CSV files
  • Implemented asynchronous file content reading to minimize process blocking during file uploads
  • Updated the file viewer to download HTML files directly instead of rendering them inline in the browser

Resolved Bug Fixes

Two critical bugs were resolved in this release:

  1. Fixed an issue where Base64-encoded embedded images in uploaded HTML files failed to auto-convert to public image URLs
  2. Resolved incorrect plugin billing calculation errors for commercial deployments
