## Upgrade Guide
|
|
|
|
### 1. Environment Variable Updates
|
|
|
|
1. Rename the following FastGPT environment variables — `SANDBOX_URL` and `SANDBOX_TOKEN` are now `CODE_SANDBOX_URL` and `CODE_SANDBOX_TOKEN`:
|
|
|
|
```bash
|
|
# Old
|
|
SANDBOX_URL=<code sandbox address>
|
|
SANDBOX_TOKEN=<code sandbox credential (can be empty; auth was added in 4.14.8)>
|
|
# New
|
|
CODE_SANDBOX_URL=<code sandbox address>
|
|
CODE_SANDBOX_TOKEN=<code sandbox credential>
|
|
```
|
|
|
|
2. Internal-network security checks are now disabled by default. To re-enable them, set the environment variable `CHECK_INTERNAL_IP=true` (applies to fastgpt, fastgpt-pro, and fastgpt-sandbox).
|
|
|
|
### 2. Update Images
|
|
|
|
- FastGPT image tag: v4.14.9.1
|
|
- FastGPT Commercial Edition image tag: v4.14.9.1
|
|

|
|
|
|
## API Changes
|
|
|
|
The `/api/core/chat/getPaginationRecords` endpoint now returns a `useAgentSandbox: boolean` field indicating whether the AI sandbox tool was used in the current conversation turn. The `llmModuleAccount` and `historyPreviewLength` fields will be removed soon — please migrate away from them as soon as possible.
|
|
|
|
## New Features
|
|
|
|
1. Added AI Sandbox — attach a sandbox tool to the AI for richer operations. (Currently available on the cloud service only; a lightweight self-hosted deployment will ship in the next release.)
|
|
2. Publish channels now support WeChat personal accounts.
|
|
3. AgentV2 context now adapts to the paused state.
|
|
4. Introduced a logger SDK with Metrics tracking.
|
|
5. Updating a single Knowledge Base entry now also refreshes the collection's update timestamp.
|
|
6. Form file inputs now support opening files for preview.
|
|
|
|
## Improvements
|
|
|
|
1. API-based Knowledge Base sync now has additional fallback methods for retrieving file names.
|
|
2. Added SSRF protection to the HTTP tool.
|
|
3. Improved compatibility with more MCP JsonSchema fields — older versions could not handle mixed-type fields.
|
|
4. Optimized parts of the workflow runtime pool logic to reduce computational complexity.
|
|
5. Replaced DFS with Tarjan's SCC algorithm for edge grouping in the workflow runtime, resolving issues where complex cyclic workflows failed to run.
|
|
6. System toolsets no longer display a version number (since they have no selectable versions).
|
|
|
|
## Bug Fixes
|
|
|
|
1. When a workflow nested a plugin, plugin execution details were not properly preserved. Also cleaned up all tool-type prefixes.
|
|
2. Updating and saving an MCP toolset could prevent it from being called correctly (due to an incorrect toolId lookup).
|
|
3. The search box was missing from the API Knowledge Base file list.
|
|
4. Workflow variable values containing special characters (`$.`) caused incorrect value substitution.
|
|
5. Referencing an agent tool in a workflow caused a version retrieval error.
|
|
6. When switching from a model that supports certain parameters to one that does not, the unsupported parameters were not removed, causing model invocation failures.
|
|
7. Closing a shared link's display status caused AI responses in the chat history to render incorrectly.
|
|
8. Re-opening the preview dialog in workflow preview mode lost form input content.
|
|
9. Custom fields in subscription plans were not applied.
|
|
10. The login endpoint had an async session issue that produced error logs.
|
|
12. The condition evaluator was missing selectable conditions for the `arrayAny` type.
|
|
13. Video/audio custom file type workflows were missing file link variables at the start node.
|
|
14. User input messages were not escaped to Markdown format.
|
|
15. Fixed partial context concatenation errors in AgentV2.
|
|
|
|
## Code Improvements
|
|
|
|
1. Fixed a monorepo issue in Commercial Edition development where different React references required a full package reinstall.
