New Features πŸš€β€‹

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.

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.

πŸ›‘οΈ Improved Guardrails Message Handling​

Guardrails message handling has been improved to reduce repeated violations from historical messages.

Messages that trigger violations are now replaced with placeholders so past chat history does not re-trigger rules, and violation metadata and context are available in the conversation details pane for faster investigation.

πŸ” Replace Knowledge​

You can now replace knowledge sources used by agents without losing associated metadata such as annotations, attribution, tags, and mappings.

Background validation runs during replacement to ensure the new source is compatible before the swap is finalized.
