If you work with data, build dashboards, or just rely on Power BI to make sense of your numbers, then May 2026 is a release worth reading about. Microsoft has packed in meaningful upgrades this month, and the best part? Most of them are built to make your day-to-day work noticeably easier.
Here’s everything new, in the order Microsoft rolled it out.
The bigger takeaway is that May 2026 improves Power BI adoption by making reports easier to use and insights easier to access.
Copilot & AI: Better Answers, Right Within
1. Explore improvements
What changed: With the May 2026 updates, Power BI makes the “Explore” experience more intuitive and user-friendly. Users can now filter to view only the relevant fields via perspectives, automatically expand new matrix data, turn on totals directly from the toolbar, and keep formatting when exploring.
Why it matters: Data analysis becomes faster, simpler, and more accessible for business users. No manual interpretation needed, just instant clarity at a glance. That’s the idea.
2. Copilot summary shortcuts
What Changed: The update introduces smarter Copilot summary shortcuts. A single click now allows users to get AI-powered summaries for full reports or specific visuals, with Copilot surfacing the key trends, changes, and insights automatically.
Why It Matters: By cutting down manual analysis, these smarter shortcuts help business users get to the key takeaways faster and with far less effort.
3. Copilot Narrative Visual: Embedding in Customer Applications (Preview)
What Changed: Businesses can now embed AI-generated report summaries directly into their own apps, with no Power BI sign-in required for end users.
Why It Matters: Contextual insights and conversational analytics can now live inside customer-facing experiences, thereby bringing data closer to the people who need it, without the friction of platform switching.
4. New Copilot Tooling Format (Preview)
What Changed: Copilot metadata is now stored in a Git-friendly, documented structure built for direct editing and source control, decoupled from Q&A and moved outside the Analysis Services database.
Why It Matters: Reduced memory load, better performance for metadata-only scenarios, and cleaner version control. This offers data teams more flexibility and efficiency when preparing data for AI.
Reporting Enhancements Designed for Daily Use
The strongest May 2026 improvements are the ones that reduce effort at every step, from report setup to exploration to everyday decision-making.
1. Visual Calculations and Custom Totals (Generally Available)
What Changed: Users can now add running sums, moving averages, percent of parent, and other calculations directly to a visual. So, no DAX measures or semantic model changes needed.
Why It Matters: Faster, lighter analysis without touching the data model. As a result, analysts can build context-aware calculations on the fly, right where the data is displayed.
2. Custom totals: None and Average (Generally Available)
What Changed: Table and matrix totals now include None and Average options, giving users more control over how totals appear in reports.
Why It Matters: Cleaner, more business-aligned reporting without workarounds. The totals reflect exactly what the audience needs to see.

Why It Matters: Less manual entry, faster execution. Workflows feel lighter and more intuitive for everyday business users.
6. Input slicer numeric column support (Generally Available)
What Changed: Input slicers now support advanced numeric filtering with expressions like ranges, greater-than, and less-than values for more precise data interaction.
Why It Matters: More filtering power directly in the report. Users get the specific data cuts they need without extra visuals or complexity.
7. Matrix auto-expand for embedded visuals and Explore (Generally Available)
What Changed: Matrix hierarchies now automatically expand in embedded visuals and Explore mode, removing the need for manual interaction to reveal data.
Why It Matters: Faster, uninterrupted data navigation means insights surface immediately without extra clicks getting in the way.
8. Text box list formatting improvements (Generally Available)
What Changed: Text boxes now correctly preserve list structures, indentation, and bullet formatting pasted directly from Word documents.
Why It Matters: Cleaner report design with less manual fixing because what you paste is what you get, every time.
9. Azure Maps formatting pane (Generally Available)
What Changed: The Azure Maps visual now features a redesigned formatting pane that aligns with Power BI’s modern, consistent customization experience.
Why It Matters: A familiar, unified interface means less time figuring out map settings and more time building meaningful spatial visuals.
10. Modern visual defaults improvements (Preview)
What Changed: Updates include a refreshed theme experience, more reliable slicer behavior, and improved canvas consistency across report pages.
Why It Matters: A smoother, more predictable development experience ensures fewer surprises when building and previewing reports.
11. Column fixed and default width for table and matrix (Generally Available)
What Changed: Report creators can now set fixed or default column widths for table and matrix visuals, with separate control for desktop and mobile layouts.
Why It Matters: Greater layout consistency and control, so reports look polished and intentional across every screen size.
12. Subscriptions support for Power BI reports in org apps (Preview)
What Changed: Users can now subscribe to Power BI reports within organizational apps, receiving scheduled snapshots and updates directly via email.
Why It Matters: Key insights reach stakeholders automatically. No need to log in and check manually, keeping everyone informed on schedule.
Modeling
Faster Access to Web Modeling for Semantic Model Authors
What Changed: Users with edit permissions are now taken directly to the web modeling experience, with most model details page actions integrated into the model view.
Why It Matters: Fewer clicks to get to work, now semantic model authors land where they need to be instantly, without navigating through an extra page.
Data Connectivity
New Get Data Experience in Power BI Desktop (Preview)
What Changed: A redesigned Power Query Get Data experience now offers a unified hub for discovering and connecting to data sources, with improved discoverability, a streamlined connection flow, keyboard navigation, and dark-mode support.
Why It Matters: Faster, more accessible data connection across Power BI Desktop, Microsoft Fabric, and Excel. The result? A consistent experience that reduces friction right at the start of every analysis.
