Power BI Copilot News: Every Major Update Through September 2026

By Akshay Pol, Co-Founder & Lead AI Strategist. Last reviewed by Nakul Joshi, CTO. Updated October 2026.

Microsoft ships Power BI Copilot updates monthly across scattered blog posts, community forums, and Microsoft Learn documentation. This page collects what actually shipped, what it does, and who it affects through the September 2026 release cycle.

The September 2026 release cycle marks a turning point: Microsoft is transitioning Copilot from a side-panel drafting assistant into an autonomous, agentic system deeply grounded in the semantic model and the wider Microsoft 365 ecosystem. According to the Microsoft Fabric Feature Summary, several core capabilities reached general availability or expanded preview this month.

BI developers can now delegate work to an agent — whether building from scratch or extending existing solutions — review the result, and refine it rather than starting from scratch every time.

The powerbi-authoring plugin was recently updated to support report authoring for remote semantic models in the Power BI service and an expanded range of supported visuals, including custom visuals.

This matters most for BI developers who spend significant time on the initial authoring pass. The agent handles that pass; the developer reviews and refines.

A preview of Microsoft 365 Copilot integrated directly into Power BI is rolling out. Users get shared conversation history across M365 Copilot experiences instead of starting a new conversation each time they switch applications.

In practice: A sales leader can use Fabric IQ to identify which regions are behind plan, then use Work IQ to connect those results with customer emails, meetings, and account plans — and kick off follow-up tasks in Cowork, all from inside Power BI.

Admin note: This is off by default. A new setting in the Fabric admin portal controls whether the integration is available, giving administrators time to evaluate before introducing it to users. It requires a Microsoft 365 Copilot license during the preview period.

Users can find and ask questions about Power BI reports and semantic models directly from Microsoft 365 Copilot Chat. They can search for content, attach a report, or paste a link and ask in natural language.

Powered by Fabric IQ, responses use the data, measures, relationships, and business logic already defined in your semantic model. The experience now also supports Microsoft Purview DLP policies, so existing data classification controls apply to conversational analytics without separate configuration.

This is the September update almost no coverage has mentioned.

Semantic model editors can now block read-only users from accessing a model through Copilot and Microsoft’s remote MCP tools. The setting applies across Power BI Copilot, M365 Copilot Chat and Cowork, data agents, remote Fabric MCP servers, and Power BI MCP servers.

That is the ability to enforce: Copilot can query this model, but only for users with edit access — not all report consumers.

For organizations with sensitive financial, executive compensation, or HR models, this is the control they have been waiting for.

The Power BI Authoring MCP now runs remotely, enabling AI applications to create and modify semantic models in Fabric workspaces without installing anything locally. This also unblocks Mac users, since the server no longer requires local binaries.

To understand the full Copilot landscape, several key updates from earlier in 2026 and late 2025 set the foundation:

Copilot in Power BI requires a Fabric capacity workspace (F64 or higher, or equivalent Premium capacity P1+) and Copilot enabled at the tenant level.

The M365 Copilot integration additionally requires a Microsoft 365 Copilot license per user. The standalone and report pane Copilot experiences do not require a separate per-user Copilot license beyond standard Power BI licensing.

The Q&A visual is being retired.

The Q&A natural language experience for creating dynamic values in the Narrative visual is being replaced with a deterministic value selection UI, tied to the broader Q&A tool deprecation. If your reports use Q&A-authored values, plan to migrate.

Retirement timeline: The official retirement timeline is February 2027.

Power BI is being engineered to behave less like a standalone BI tool and more like a governed, AI-capable layer within a broader data platform. The Copilot updates push it toward embedded intelligence that business users can rely on without technical mediation.

The immediate action for most organizations:
