V4.8.17 (Includes Migration Script)

Upgrade Guide

1. Update images:

• Update the fastgpt image tag to v4.8.17-fix-title
• Update the fastgpt-pro commercial edition image tag to v4.8.17
• Sandbox image update is not required

2. Run migration script

From any terminal, send an HTTP request. Replace {{rootkey}} with the rootkey from your environment variables, and {{host}} with your FastGPT domain.

curl --location --request POST 'https://{{host}}/api/admin/initv4817' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'

This migrates user-bound OpenAI accounts to the team level.

Completions API response changes

The /api/v1/chat/completions endpoint response has been updated. Nodes that use models (chat nodes, tool nodes, etc.) will no longer return a tokens field. Instead, they return inputTokens and outputTokens fields representing the input and output token counts respectively.
