This release includes an exciting new option to turn on an agentic retrieval API from Azure AI Search (currently in public preview).
Read the docs about it here:

You can also watch this talk from @mattgotteiner and @pamelafox at Microsoft Build 2025 about agentic retrieval:

Please share your feedback in either the issue tracker or discussions here. Since the retrieval API is in public preview, this is a great time to give feedback to the AI Search team.
