Important
Edge RAG Preview, enabled by Azure Arc is currently in PREVIEW. See the Supplemental Terms of Use for Microsoft Azure Previews for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.
February 2026
Release of extension version 0.8.5
This release focuses on reliability, stability, and security improvements for Edge RAG. These updates make the system more robust and predictable, with better error handling and enhanced security protections.
Enhanced search reliability
Search operations are more dependable with improved deep search accuracy for complex queries. You get clearer error messages that tell you whether the system is unavailable or the knowledge base is empty, so you know exactly what's happening and can take the right action.
More robust data ingestion
Data ingestion now handles edge cases gracefully, including files without extensions and empty folders. The system reports which files it skipped and why, giving you full visibility into the ingestion process. NFS connections validate accessibility, sockets, and permissions upfront, with clear error messages when problems occur.
Improved system reliability
Configurable timeouts for document conversion, SharePoint connections, LLM inference calls, and database operations prevent indefinite hangs and resource exhaustion. Operations fail predictably with clear diagnostics, so you can tune settings for your environment.
Better troubleshooting
Deployment failures now provide accessible logs, so you can identify root causes faster without escalating to support. This improvement reduces time to resolution and helps you get Edge RAG running smoothly.
Critical security updates
This release addresses two important vulnerabilities: a critical Next.js Denial-of-Service vulnerability (GHSA-5j59-xgg2-r9c4) and a high-severity Langchain XXE vulnerability that could allow unauthorized file access. Dependency updates also resolve version conflicts and improve overall system stability.
November 2025
Release of extension version 0.8.2
This release of Edge RAG introduces several new features, enhancements, and improvements designed to expand capabilities, improve performance, and streamline the user experience.
Deep search
Find the most relevant information with the new deep search model. Deep search uses production-class LazyGraph RAG with industry-leading RAG inferencing quality. Edge RAG now explores and connects data across sources at query time, so you get comprehensive answers without heavy upfront processing. For more information, see Search types in Edge RAG.
High-fidelity parsing
Choose between basic text extraction or advanced parsing to capture tables, images, and more. By using advanced parsing, Edge RAG offers OCR-enabled support for documents, tables, and images. Tailor data ingestion to your needs for more accurate results. For more information, see Configuring the chat solution for Edge RAG and Advanced data parsing for Edge RAG.
Performance and scale
Experience up to 5× faster query performance for hybrid search and 100× faster ingestion of live-streamed images from the previous Edge RAG extension version 0.1.5.
Advanced search and chat experience
Edge RAG now offers a more powerful and flexible search and chat experience, making it easier to find information and interact with your data through new capabilities and interface improvements.
- Use hybrid multimodal search to retrieve images and deliver responses with rich visual content. For more information, see Search types in Edge RAG.
- Enjoy markdown-formatted responses that support images and rich text for responses that are easier to read and interpret.
- Chat directly with the language model, without using your organization’s data as context. Use the model only option to ask general questions, test the model’s capabilities, or get responses that aren’t influenced by your ingested data. Switch between knowledge-based chat and model-only chat to fit your needs. For more information, see Configuring the chat solution for Edge RAG.
Preview support for disconnected scenarios
Edge RAG is supported as part of a preview for disconnected operations for Azure Local.
