New Features 🚀​

Agentic RAG​

The new Agentic RAG knowledge integration mode gives agents more control over how they use knowledge sources. Agents can refine search queries, filter documents using metadata tags, and perform multiple search strategies before responding.

This improves context awareness and helps retrieve more relevant sections before the final answer is generated.

Chat Completion Preview​

The new Chat Completion preview in Agent Design Studio makes it easier to test full chat history management. You can edit existing messages, add new ones, and manually shape the conversation history before running the agent.

This gives you a clearer way to understand how chat history affects agent behaviour and how to reproduce that behaviour in your own client implementation.

Enhancements ✨​

Agent Subtenant Change​

Agents can now be moved between subtenants more easily. Select the new target subtenant from the General Configuration panel in Agent Design Studio, and the agent will be migrated with the required data.

Connections, API keys, and other configurations tied to the original subtenant are not transferred automatically and must be reconfigured if needed.

Chat Widget​

Specific Agent Version​

You can now specify which version is executed when using the Chat Widget, allowing for better version management and control.

Fully customizable CSS​

We have released a new resource for configuring the Chat Widget with fully customizable CSS classes. This gives you more direct control over the widget's visual style when you want to manage its appearance through your own CSS.

Azure Safety Guardrails Provider​

Azure Safety can now be used as a guardrails provider for your agents, expanding the available options for safety and response control.
