## 🖥 Desktop Client
|
|
|

|
|
|
Highlights:
|
|
|
|
- **Out of the box**: the full Agent runtime is bundled — launch right after install, no need to set up Python or other dependencies
|
|
- **Full chat experience**: streaming replies, session management, tool-call step display, Markdown rendering, plus sending and previewing images / videos / files
|
|
- **Visual management**: configuration, models, knowledge base, scheduled tasks, skills, and memory pages mirror the Web console, all manageable in the native UI
|
|
- **Channel onboarding**: connect messaging channels by scanning a QR code right inside the app
|
|
- **Auto update**: automatic version checks and one-click updates, with download speed optimized across regions
|
|
- **Native experience**: first-run onboarding, follows the system language, and platform-adaptive window interactions
|
|
|
|
|
|
## 📚 Knowledge Base
|
|
|
|
- **Create & import documents**: create new documents or import external ones directly from the UI
|
|
- **Automatic index maintenance**: the knowledge base index is rebuilt automatically from the actual directory tree, preventing index drift or lost documents
|
|
- **Vectorization fix**: the index now reuses the unified embedding provider, ensuring real semantic vectors instead of falling back to keyword search
|

## 🔌 On-demand MCP Tool Retrieval
|
|
|
|
To address context bloat when many MCP tools are connected, we added **on-demand tool retrieval**: relevant MCP tools are loaded on demand via RAG vector search based on the current task, reducing the context taken up by irrelevant tools. Thanks @fengyl07
|
|
|
|

|
|
|
|
## 🌏 Traditional Chinese Support
|
|
|
|
The Web console, logs, and documentation now support **Traditional Chinese (zh-Hant)**; the interface language can follow the system or be switched manually. Thanks @anomixer (#2935)
|
|
|
|
## 🤖 New Models
|
|
|
|
- Added support for **claude-sonnet-5** and **claude-fable-5**
|
|
- Added support for **doubao-seed-2-1-pro** and **doubao-seed-2-1-turbo**
|
|

|
|
## 🔒 Security Hardening
|
|
|
|
- **Sensitive file read protection**: hardened access to credential and other sensitive files to prevent bypass reads. Thanks @fengyl07 (#2913)
|
|
- **Browser access protection**: blocks browser requests targeting internal network and cloud server internal endpoints, reducing the risk of being tricked into reaching internal services. Thanks @Jiangrong-W
|
|
- **Safer config parsing**: config content is parsed in a safer way to avoid potential code execution risks. Thanks @shunfeng8421
|
|
|
|
## 🛠 Improvements & Fixes
|
|
|
|
- **Custom provider support**: embedding and vision models can now use custom providers; also fixed a memory query issue on Windows. Thanks @HnBigVolibear
|
|
- **More reliable file editing**: better preserves original indentation, and fuzzy matching no longer touches unrelated content. Thanks @weijun-xia (#2942)
|
|
- **Command output encoding fix**: fixed garbled Chinese characters when a command produces large output. Thanks @weijun-xia (#2941)
|
|
- **Azure OpenAI fixes**: fixed streaming output and related configuration issues for Azure OpenAI. Thanks @Tunnello
|
|
- **WeCom Smart Bot**: added channel docs for the webhook (callback) mode. Thanks @6vision
|
|
