What's New in Version 0.671.0

Released on February 22, 2026

This release introduces enhanced agentic tooling with interleaved thinking, streamlined external model management, voice agent channel integrations, and important platform fixes! 🚀

🎯 Enhanced Agentic Tooling & MCP Handling​

Interleaved Thinking for Smarter Tool Calling​

We've significantly enhanced our agentic tooling capabilities by implementing interleaved thinking for tools calling and MCP (Model Context Protocol) handling. This breakthrough approach allows agents to think and act in a more fluid, adaptive manner.

Key Improvements:

  • Interleaved Reasoning - Agents can now interleave thinking processes with tool invocations for more intelligent decision-making
  • Enhanced MCP Integration - Improved handling of MCP servers with better context awareness and error recovery
  • Smarter Tool Selection - More accurate and contextually appropriate tool selection during complex workflows
  • Adaptive Execution - Dynamic adjustment of tool calling strategies based on real-time feedback

This enhancement delivers more capable and responsive agents that can handle complex multi-step tasks with greater precision and adaptability.

🤖 Expanded External Model Management​

Instant Access to Latest Models from Leading Providers​

We've improved our external model management system to ensure new models from OpenAI, Anthropic, and Vertex AI are immediately available to our users upon release.

🎙️ Voice Agent Channel Integrations​

Native Communication via Email, SMS & WhatsApp​

Voice agents can now communicate through multiple channels, enabling them to send messages via email, SMS, and WhatsApp. This opens up entirely new use cases for voice-enabled automation.

Channel Capabilities:

  • Email Integration - Voice agents can send emails using your custom configured channels or the default ToothFairyAI generated email addresses
  • SMS Messaging - Send text messages directly from voice agents to any mobile number
  • WhatsApp Support - Native WhatsApp Business API integration for instant messaging
  • Simple Configuration - Enable channels by simply configuring custom credentials or using our default email service

This integration transforms voice agents from standalone interfaces into comprehensive communication hubs.

🛠️ Improvements & Fixes​

Knowledge Hub Document Title Editing​

We've fixed an issue where editing a knowledge hub file or document title would incorrectly append the file extension in a loop when refreshing the page.

Fix Details:

  • Proper Extension Handling - File extensions are now correctly managed when editing document titles
  • No Duplicate Extensions - Resolved the loop that caused extensions to be repeatedly appended
  • Better Title Persistence - Titles now save and display correctly across page refreshes

Your knowledge hub documents now maintain clean, properly formatted titles without any extension-related issues.

📋 Summary​

This update includes:

  • Enhanced Agentic Tooling - Interleaved thinking for smarter tool calling and MCP handling
  • External Model Management - Immediate availability of new models from OpenAI, Anthropic, and Vertex AI
  • Voice Agent Channels - Native email, SMS, and WhatsApp integration for voice agents
  • Knowledge Hub Fix - Resolved document title editing issue with file extensions
