🧬 Self-Evolution

CowAgent introduces Self-Evolution, letting the agent go beyond completing a single task and keep improving through everyday collaboration with you:

• Automatic review after idle: Once a conversation goes idle, the agent reviews it in the background to fix problems a skill exposed in use, create reusable new skills, follow up on unfinished tasks, and record important information into memory and the knowledge base
• Silent by default, notify on demand: It reports what it changed only when it actually made a change, and stays silent otherwise
• Safe and reversible: Every review is backed up beforehand and can be undone at any time. Built-in skills are protected, and all reads and writes stay within the workspace

Enabled by default for new installs. Existing users can turn it on with a single click in the Web Console under Settings → Agent Config.

💬 Web Console Upgrades

The Web Console chat experience gets several enhancements:

• Message management: Edit, delete, and regenerate both user and bot messages; code blocks now include language labels and a one-click copy button
• Parallel sessions: Run multiple sessions at the same time without interference, with live streaming automatically resumed when you switch back to a session
• Refinements: Drag and drop files anywhere in the chat view; automatically switch to a sibling session after deleting the active one

Thanks @core-power (#2865)

🧩 Cross-platform MCP Enhancements

• Windows compatibility fix: Fixed stdio communication failing on Windows, and made the server timeout configurable via mcp.json
• Concurrent calls: The sse and streamable-http transports now support concurrent calls across sessions for faster multi-tool responses

🛠 Improvements & Fixes

• More reliable cancellation: Fixed cases where a streaming reply could not be interrupted
• CLI: cow status now shows the current project path
• Hardened deployment security: The credential-file block is narrowed to ~/.cow/.env so other directories are no longer affected (Thanks @orbisai0security #2863); the WeChat Official Account now rejects webhook requests when wechatmp_token is empty
• Group task board plugin: Added the group task board plugin source. Thanks @Wyh-max-star (#2853)
