## Upgrade Guide

### 1. Update Images

- Update FastGPT image tag: v4.14.7.2
- Update FastGPT commercial edition image tag: v4.14.7.1
- Update fastgpt-plugin image tag: v0.5.4
- mcp_server: no update needed (4.14.7 image is not available; use the previous version)
- sandbox: no update needed
- Update AIProxy image tag: 0.3.15
- mongo: no update needed

### 2. Update System Environment Variables

The logging system has been updated, including log output, log collection, and log analysis.

```dotenv
# Remove these environment variables
LOG_LEVEL=
STORE_LOG_LEVEL=
SIGNOZ_BASE_URL=
SIGNOZ_SERVICE_NAME=
SIGNOZ_STORE_LEVEL=

# Add the following 6 variables (same variables for fastgpt, fastgpt-pro, fastgpt-plugin, and fastgpt-mcp-server)
LOG_ENABLE_CONSOLE=true # Enable console output
LOG_CONSOLE_LEVEL=debug # Minimum log level for console output
LOG_ENABLE_OTEL=false # Enable OTEL log collection
LOG_OTEL_LEVEL=info # Minimum log level for OTEL collection
LOG_OTEL_SERVICE_NAME=fastgpt-client # Service name passed to the OTLP collector
LOG_OTEL_URL=http://localhost:4318/v1/logs # Your OTLP collector URL. Do not omit /v1/logs
```

### 3. Update System Plugins

Go to the Plugin Marketplace and update the following system tools (skip this step if you already upgraded to 4.14.6). You can also directly download the [zip package](https://github.com/labring/fastgpt-plugin/raw/refs/heads/main/.github/assets/upgrade_pkg.zip) and install it.

* base64Decode: Base64 decode conversion
* dallle3: DALL-E 3 image generation
* docDiff: Document diff comparison
* drawing: BI charts
* gptImage: GPT image generation
* markdownTransform: Markdown file conversion
* mineru: MinerU PDF parsing
* minimax: MiniMax chat
* openrouterMultiModal: OpenRouter multimodal
* stability: Stability image generation

### 4. Run the Upgrade Script

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

```bash
curl --location --request POST 'https://{{host}}/api/admin/initv4147' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'
```

1. Adds chat log records containing errors to the statistics table.

### 5. API Changes

In the new version's chat records, the `type` field has been removed from the value. `/api/core/chat/getPaginationRecords` has temporary backward compatibility, but users of this API should update their value parsing logic as soon as possible -- simply check whether fields like `text`, `tools`, etc. exist.

## New Features

1. Context-engineering-based Agent mode, suitable for long task decomposition scenarios. (Beta)
2. Temporarily added LLM request tracing for debugging. All LLM request bodies and responses are retained (default retention: 6 hours, configurable via `LLM_REQUEST_TRACKING_RETENTION_HOURS`).
3. Knowledge base search now supports filtering by collectionIds.
4. Model monitoring now includes cache hit rate.
5. Share link with custom authentication: the finish event now transmits chatId.
6. Chat log list now includes an error-only filter option.
7. Chat log list now supports precise user filtering.
8. Dependency pre-check: validates infrastructure and sub-service availability at startup for easier troubleshooting.
9. MCP service parsing now supports `$ref` syntax in schemas.
10. Rebuilt the logging system using [LogTape](https://logtape.org/), covering log output, collection, and analysis. Mongo-based log storage has been removed -- use an OTEL collector instead.

## Improvements

1. Improved UX for tool selection and knowledge base selection in Chat Agent.
2. MCP now automatically filters out extraneous fields on save to maintain mongo 4.x compatibility.
3. Backend automatically filters out unconfigured tools to prevent model errors from calling unconfigured tools. Uses the same filter function to ensure frontend-backend consistency.
4. Added memory selection for workflow AI models in chat log mode.
5. Tool calls now auto-fill empty arguments with `"{}"` to prevent errors from providers that don't support empty strings.
6. Adapted for Kimi 2.5 tool calls in thinking mode.
7. Improved internal network domain validation.
8. Orphaned edges are removed before workflow execution.
9. When calling workflows via API with file links, the file type is now saved directly from the input instead of being inferred from the URL, ensuring 100% correct file types.

## Bug Fixes

1. Some global variable types had incorrect defaultValueType assignments in workflows.
2. Workflow AI node thinking output was not rendered correctly.
3. Precisely retrieves permissions for individual MCP sub-tools to prevent unauthorized access.
4. Toolset ToolName starting with a number caused tool call failures.
5. Converting a simple app to a workflow did not duplicate the avatar.
6. When importing workflows, reference-type model fields were incorrectly identified as invalid models and cleared.
7. On iPhone Safari, share links had a chance of triggering requests with an empty uid on first visit.
8. MCP could not pass file links when exposing an Agent.
9. Creating an HTTP tool with variables in the body caused JSON parsing errors.
10. Workflow canvas auto-positioning stopped working after switching tabs.
11. When a workflow node encountered an uncaught system error, it did not correctly follow the error capture branch.

## Plugin Updates

1. Added user info retrieval tool.
2. Added Kimi 2.5 model preset.

## Code Quality

1. Added vector database integration tests.
2. Improved packages/global unit test coverage to 90+.
