Release Notes

Welcome to the Flametree release notes! Here you’ll find detailed information about new features, improvements, and updates in each version of our AI platform.

Flametree 4.6​

May 18, 2026

Flametree 4.6 brings two major updates to the platform: a completely new visual AI campaign builder and a powerful tenant-wide Knowledge Sources system.

🎯 Visual Outbound Campaign Builder​

Create outbound campaign flows visually — no code needed.

What’s new:

• Visual workflow builder. Set up multi-step campaigns with triggers, conditions, and actions, including AI agent steps — no code required.
• Structured campaign data. Manage participant information across the campaign lifecycle, used for data upload, condition rules, AI agent communications, and more.
• Scheduling at the campaign level. Configurable timing, retry rules, and quiet hours, defined on the campaign itself rather than on each agent.
• AI agents as workflow steps. Plug agents into the workflow as steps, alongside waits and conditions.
• Live monitoring. Campaign progress, current statuses, and per-participant results in a single view.
• Analytics dashboards. Campaign efficiency and business outcomes aggregated across runs.

📦 Tenant-level Knowledge Sources​

Create knowledge sources of multiple types, connect them to AI agents, track usage, and surface missing knowledge.

What’s new:

• One source, many agents. Connections are editable from both sides: from an agent via the Manage modal, where each source has its own Connect / Disconnect action, or from the source itself via the connected-agents list in its Edit view.
• FAQs replace flat Q&A lists. Q&As are now organized into named FAQs. Add Q&As manually, or generate a batch from a file — the system extracts question-answer pairs from CSV, PDF, DOCX, XLSX, MD, or HTML.
• Vector Search toggle per FAQ. For every FAQ connected to an agent, you choose how it’s used: with Vector Search on, the agent retrieves relevant Q&As through semantic search (best for large FAQs); with it off, the entire FAQ is included in the system prompt (best for short FAQs where you want guaranteed wording).
• Unanswered Questions. A new card collects questions the agent couldn’t answer. From there, a question can be turned into a Q&A inside the chosen FAQ, with the link to the original incident preserved.
• Manual indexing control. Index and Stop buttons on every source, with status updating in real time.
• Usage visibility on the agent. On the Knowledge Base tab in an agent’s Simple mode, tab labels (Core, Q&A, Plain Text, Websites, Files, YouTube) show the number of sources of each type connected to the agent. The Q&A list has a new Usage Count column — how many times each question has been used to answer a conversation — sortable so you can quickly find Q&A entries that are working and ones that aren’t.

Migration note. Existing agents are not auto-migrated and continue to use their current Knowledge Base. New agents use Knowledge Sources. We recommend trying Knowledge Sources on a new or test agent first, then migrating production agents manually on your own timeline. Both systems run side by side.

💳 Billing page redesign​

One screen for plan options, current subscription, trial status, and session usage.

What’s new:

• Monthly session limit per tenant to cap your own spend.
• Full history of plan transitions (date, source plan, target plan) for audit.

🌐 Automatic Creation of Demo Web-page with Web-Widget for AI Agent​

You can now create a demo web page with your AI agent web-widget in the agent’s Simple mode → Channels → Web-widget via the Open demo page button.

• Share the page with others to preview and test your AI agent and web-widget.
• No platform account is required to interact with the agent.

🖼️ Filter sessions by attachment​

A new Only sessions with attachments toggle in the Sessions filter narrows the list to conversations that include images or files.

Flametree 4.5​

March 17, 2026

⚙️ Simplified AI Agent Configuration Interface​

Flametree introduces a redesigned AI agent configuration interface. The new interface simplifies how AI agents are created, configured, and tested within the Flametree platform.

Key capabilities include:

• A structured configuration model covering:

  • Identity & Role — the agent’s name and the company it represents
  • Speech Style & Tone — communication style, formatting rules, and response length
  • Primary Task — the core conversation logic, described in plain text step by step
  • Welcome Message — optionally predefine the first message the agent sends
  • Human Handoff — enable transfer to a live operator when needed

• An integrated Playground for real-time testing of agent behavior, always visible alongside the configuration.

• Multiple knowledge sources, including websites, files, structured Q&As, plain text content, and YouTube videos — each with real-time processing status.

• Built-in connectivity to web widgets (with customizable appearance), Telegram, and WhatsApp.

• Automated data capture from conversations — standard fields (Name, Email, Phone, Topic) toggled with one click, plus custom fields defined as named cards.

The update is designed to make agent configuration more transparent while enabling faster deployment and iteration. Additional settings are available in Advanced mode, which restores the full YAML-based editor via the toggle in the top right.

A short walkthrough video demonstrates the new configuration workflow.

📱 Mobile Support​

Flametree portal is now adapted for mobile devices. The mobile version includes:

• A step-by-step wizard for creating new agents
• A Playground for testing any running agent

Full platform functionality remains available in the desktop version.

Flametree 4.4​

February 23, 2026

This release introduces the Planning Agent, delivers enhancements to the Human Agent and 360 Customer View workspaces, enhances the Deep Analytics mechanism, adds Instagram as a supported communication channel, introduces a configurable tenant-level monthly session limit, and improves automated knowledge base generation from websites using the llms.txt mechanism.

🧠 Planning Agent​

A new type of AI agent designed to handle complex, multi-step tasks. The agent first generates an execution plan based on the customer request and then performs the steps sequentially, with the ability to dynamically re-plan based on execution progress and intermediate results.

💼 Human Agent Workspace and 360 Customer View Evolution​

The continuous customer communication feed has been extended with new event types, including:

• Operator transfer
• Operator assignment
• Session closure

Integration of the continuous communication feed (as in the 360 Customer View workspace) into the Human Agent workspace.

Ability to manually initiate outbound communications via:

• WhatsApp
• Telegram
• Email

For WhatsApp outbound messages sent after 24 hours, support for Meta-approved message templates.

📱 Instagram Direct Messaging Support​

Instagram Direct Messages are now supported as a communication channel.

⚙️ Tenant-Level Monthly Session Limit​

A configurable monthly session limit can now be set at the tenant level to enable better budget forecasting and usage control.

📊 Deep Analytics Enhancements​

Deep Analytics now supports the use of session parameters and communication channels during report generation, enabling more comprehensive insights.

🎨 Widget Design Enhancements​

The widget design has been enhanced to deliver a more modern, seamless, and consistent customer experience aligned with today’s leading chat platforms.

🌐 Web Knowledge Base Parsing via llms.txt​

The Web Knowledge Base source now supports parsing via llms.txt, enabling faster and more accurate extraction of website content.

A new checkbox Prefer llms.txt for website parsing is available (enabled by default).

If enabled:

• If an llms.txt file is present, it is used to determine which pages should be parsed instead of performing full website crawling.
• If an llms-full.txt file is present, only the content from this file is used, and the website itself is not crawled.

Flametree 4.3​

December 12, 2025

The Flametree 4.3 release focuses on simplifying AI agent creation, expanding segmentation and analytics capabilities, strengthening enterprise integrations, and improving messaging channel reliability and visibility.

🧙 Wizards for Fast AI Agent Creation​

Flametree now includes guided, step-by-step Wizards for AI agent creation.

With a Wizard, you can:

• Define the agent’s identity, goals, and behavior by answering a few simple questions
• Upload knowledge sources in text or video formats
• Review and fine-tune automatically generated prompts and settings

The platform then generates a ready-to-use AI agent, making it faster and easier to launch specialized agents with zero technical effort. Currently, wizards are available for creating a Website Sales Agent and an AI Twin, with more options coming soon.

🎯 Client Segmentation (360 View Upgrade)​

Client segmentation in 360 View has been significantly enhanced.

You can now:

• Build complex filters using AND / OR logic
• Use an expanded range of comparison operators
• Create queries from a new dedicated sidebar
• Save filter configurations and quickly access them from the Saved Filters tab

These improvements make it easier to identify target segments for analysis and outbound campaigns.

🔌 Model Context Protocol (MCP) Support​

Flametree 4.3 introduces support for the Model Context Protocol (MCP) — an open standard that allows AI systems to securely access tools, data sources, and enterprise services. MCP integrations can be configured in the Connectivity section.

MCP Capabilities​

• Automatic discovery of tools from remote MCP servers
• Ability to select only the required tools
• Ability to rename tools
• Support for connecting multiple MCP servers to a single AI agent

This feature reduces integration time and allows AI agents to evolve alongside your enterprise systems without hardcoded integrations.

📊 Deep Analytics Integration with 360 View​

Customer records in 360 View can now be enriched with insights generated by Deep Analytics.

How it works: If a field in 360 View matches the name of a Deep Analytics category, the analyzed value is automatically written to the customer record after session analysis.

Example: You can analyze which product categories prospects are interested in, store these insights in the customer profile, and use them for segmentation and outbound campaign launches.

🔄 Updating Customer Attributes from Session Parameters​

Customer records in 360 View can now be enriched using session input parameters.

How it works: If a field in 360 View matches a session input parameter name, the parameter value is automatically saved to the customer record.

Example: If a lead is acquired through advertising, UTM data (such as utm_source or utm_campaign) passed as session parameters is saved directly into the 360 View record. This enables segmentation by acquisition channels.

🚀 Campaign Result Standardization​

All campaigns now include two standardized fields — Result Flag and Result Datetime — to ensure consistent tracking and reporting of campaign outcomes across different campaigns.

📊 Improved Deep Analytics Reports​

You can now hide low-value metrics in Deep Analytics reports to focus on meaningful insights. Configure the min_value parameter in the report YAML (for example, min_value: 1.0), and rows below the specified threshold will be automatically excluded. This helps keep reports focused on the most meaningful insights.

👥 Expanded Contact Details Visibility​

The Contacts panel on the Sessions and Human Agents screens now displays additional customer fields.

In addition to the customer name, the panel may show:

• Email
• Phone
• WhatsApp / Telegram / LinkedIn
• Open in 360 button for direct profile access

Empty fields are automatically hidden to keep the interface clean.

💬 Messaging Channel Improvements​

📘 Facebook​

We have completely redesigned the integration for improved stability and added support for sending product images from the Catalog as carousel messages.

📱 WhatsApp​

Delivered and Read message statuses are now available for analytics and reporting.

Flametree 4.2​

November 17, 2025

The Flametree 4.2 release introduces a unified communication experience in Customer 360, updated Integration Settings, and several platform enhancements.

✉️ Unified Message Feed in Customer 360​

All customer communications with an AI agent now appear in a single continuous feed, similar to modern messaging apps. Live agents can start or continue conversations at any time. They can also view input and output details for every interaction, which update automatically as they scroll. This reduces switching between threads and makes information easier to find.

🔗 Integration Settings Redesign​

The Integrations section is now split into Connectivity (AI models and third-party services) and Channels (email, WhatsApp, voice, SMS, etc.). This structure makes configuration faster, clearer, and more intuitive.

📧📱 Multi-Account Channels (Email and WhatsApp)​

You can now connect multiple accounts to the same channel. AI agents and campaign stages can send outbound messages through several accounts. The system distributes traffic automatically while keeping each customer assigned to a single account. This “sticky” routing improves trust and reduces the risk of account blocking.

🖥️ New Start Screen​

A clean two-panel layout now displays agents and dashboards side by side. You can select items with a single click and open them for editing with a double click.

📊 WhatsApp Delivery Tracking​

Flametree now tracks the delivery status of every outgoing WhatsApp message. This provides clearer insight into communication performance.

✨ Additional Improvements​

• New health indicator showing real-time status of all connected accounts
• More accurate email threading for outreach communications
• Fixes for occasional attachment-sending errors in email and WhatsApp
• AI Copilot suggestions enabled by default when conversations are handed to a live agent

Flametree 4.1​

October 7, 2025

📚 Knowledge Base​

• Source filters: Now the system allows filtering by sources, shows progress of sources uploading, supports simultaneous uploads, adds corresponding name of source automatically while uploading file from filesystem
• Model health: Added health status markers for Speech-to-Text and Embedding models. Added possibility to upload video and audio files of various formats and encodings.
