💬 Web Console Improvements

This release adds several visual management capabilities to the Web Console, so more configuration can be done in the UI without editing files:

• Scheduled task management: View, edit, enable/disable, and delete any scheduled task directly in the console. The task list is sorted by enabled status first, then by next run time. Thanks @HnBigVolibear (#2892)
• Knowledge base categories and document management: The knowledge base can now be organized by category, with documents under each category managed in the UI. Thanks @yangziyu-hhh (#2893)
• Multiple custom model providers: Configure multiple OpenAI-compatible providers and switch the active one with a single click, fully compatible with existing configuration. Thanks @kirs-hi (#2877)
• Session renaming: Rename sessions manually to tell parallel tasks apart (#2897)
• Bash streaming output: Long-running Bash commands now stream their progress in real time. Thanks @yangziyu-hhh (#2879)

🧬 Self-Evolution Improvements

Building on the Self-Evolution introduced in the previous release, this version refines it further:

• Lower trigger thresholds: The default review thresholds are lowered, so everyday collaboration turns into improvements sooner
• No concurrent reviews: When a single turn runs long, the idle review no longer fires by mistake, avoiding interference with the active conversation
• Better review summary: Refined the summary prompt to keep summaries concise, raise their information density, and output them in the conversation language

Documentation: Self-Evolution

🤖 New Models

• kimi-k2.7-code: Added and set as the default Kimi model, with kimi-k2.7-code-highspeed also available
• glm-5.2: Added and set as the default GLM model

Documentation: Models Overview

🏢 WeCom Smart-Bot Callback Mode

The WeCom smart-bot channel adds an HTTP callback mode alongside the existing long connection, so deployments that cannot keep a long connection open can still connect reliably:

• Mode switching: Switch between websocket (long connection) and webhook (callback) via wecom_bot_mode
• Encrypted transport: Callback mode fully supports URL verification, message decryption, and passive-reply encryption
• Stability fixes: Fixed reply interruption, premature stream termination, and temporary image file leaks

Thanks @6vision (#2896 #2869)

🔒 Security Hardening

• Vision tool SSRF protection: Validates the target address before resolving an image URL, blocking requests to internal, loopback, and cloud server metadata endpoints. Thanks @kirs-hi (#2886)
• Web fetch SSRF protection: web_fetch validates the target address before fetching and re-validates every redirect hop, preventing redirects from bypassing the check to reach internal addresses. Thanks @christop (#2900)
• Skill install path traversal protection: Validates the path when installing a skill, preventing a malicious skill name from escaping the skills/ directory through path traversal and writing to an unauthorized location. Thanks @kirs-hi (#2886)

🛠 Improvements & Fixes

• CLI self-restart: Added the self-restart command so the agent can restart its own process
• Windows compatibility: Persist the cow CLI directory to the user PATH; fixed python -c long commands exceeding the cmd.exe length limit; avoid building greenlet from source during install
• Custom roles: The role plugin supports customization via standalone prompt files under roles/*.json. Thanks @sufan721 (#2891)
• Stability fixes: Fixed a KeyError on /cancel and an infinite loop in image compression (Thanks @kirs-hi #2888)
• Install improvements: Updated the startup script and default config; fixed ASR/TTS defaults, the self-evolution flag, and install hangs
• Vision tool stability: Increased the vision tool timeout and max_tokens
• Memory distillation: Removed the output length cap in deep-dream distillation to avoid truncating a large MEMORY.md

📦 Upgrade

Source-code deployments can run cow update for a one-click upgrade, or pull the latest code and restart manually. See the Upgrade Guide for details.
