V4.8.22 (Includes Migration Script)

Upgrade Guide

1. Back up your database

2. Update images:

• Update the fastgpt image tag to v4.8.22
• Update the fastgpt-pro commercial edition image tag to v4.8.22
• Sandbox image update is not required

3. Run migration script

Only required for commercial edition users providing SaaS services.

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/initv4822' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'

This migrates contact information to the corresponding user table.

New Features

1. AI chat node parses <think></think> tag content as chain-of-thought, enabling thinking process output for various models. You need to manually enable model thinking output.
2. Chat API optimization: conversation logs are now saved regardless of whether a chatId is provided. If no chatId is passed, a random one is generated for storage.
3. PPIO model provider.

Improvements

1. Better prompts when models are not configured, reducing conflicting messages.
2. Usage record code improvements.
3. Content extraction node: long field descriptions now wrap. Output names now use key instead of description.
4. Team management interaction improvements.
5. Chat API non-stream responses now include error fields.

Bug Fixes

1. Thinking content not counted toward output tokens.
2. Thinking chain stream output sometimes out of order with main content.

4. Some template marketplace templates had errors.
5. Guest window unable to correctly detect whether language recognition is enabled.
6. Chat log export not compatible with sub-path deployments.
7. Member list not refreshing when switching teams.
8. List API null pointer possibility when joining member data.
