Power BI in Q3 and October 2026: Everything That Changed
Power BI moved fast in the third quarter of 2026. Really fast.
Between July and September, Microsoft pushed major changes across report design, semantic modeling, Power BI Service, Direct Lake, Power Query, developer workflows, Copilot, organizational apps, mobile reporting, and AI-assisted report development.
Then October arrived with a smaller update, but one that introduced something Power BI users have requested for years: a native Gantt visual.
If you missed a few monthly updates, it would be very easy to open Power BI today and wonder when half of these capabilities appeared.
So instead of looking at each announcement in isolation, let’s go through what happened across Q3 2026, what changed in October, and what all of this means for Power BI users going forward.
