🖥 Desktop Client
Following the desktop client launched in the previous release, this version further improves browser capabilities, system compatibility, and overall experience:- Browser tool support: the client bundles browser capabilities and prefers reusing the system’s installed Chrome / Edge, with optimized browser startup and access performance.
- UI polish: refined visuals and interactions for the chat view, message bubbles, tool-call steps, and channel pages.
- Windows code signing: Windows installers are now code-signed, reducing security warnings during installation.
- Windows 7/8 support: added client support for legacy systems such as Windows 7/8, covering more environments.
- Knowledge base link fix: fixed in-document links in the desktop knowledge base that failed to navigate.
- Password login: the desktop client supports setting a login password, and fixes an issue where the window failed to load after a password was set.
🔌 MCP Remote Server OAuth Authorization
Remote MCP servers now support OAuth authorization. When connecting to third-party MCP servers that require login, authentication can be completed via the standard OAuth flow — no more manually configuring and maintaining tokens. Docs: MCP Tools⏰ Scheduled Tasks
- Silent mode: create silently-running scheduled tasks that execute in the background without pushing messages — ideal for undisturbed scenarios like data organization or periodic archiving. (#2954)
- Manual run: manually trigger an existing task to run immediately from the console, without waiting for the next schedule. (#2958)
- Preserve config on edit: fixed an issue where editing a task in the Web console could drop hidden fields such as the mode type. (#2959)
- Cross-channel task command: added the
/tasksmanagement command, compatible across channels. (#2965)
💬 Feishu Channel Improvements
The Feishu channel gains a series of message-display and interaction enhancements for a better experience.- Streaming card polish: streaming cards add collapsible panels showing the thinking process, tool calls, and execution time. (#2963)
- Markdown formatting: for non-streaming replies and scheduled pushes, messages containing Markdown are rendered as cards for clearer display. (#2962)
- Scheduler cards: the
/taskscommand is presented as cards, with the ability to enable or disable tasks right from the card. (#2961) - Quoted message context: when a user quotes a message, the quoted content is automatically added to the context sent to the Agent. (#2966)
- Remote image rendering: remote image links can now be rendered inside Feishu cards. (#2967)
- Cancel on message recall: recalling a Feishu message automatically cancels its corresponding running or queued task. (#2978)
