April 27, 2026 - Power BI, Sigma, and Tableau AI Updates
In the last 14 days, I found clear qualifying BI/AI feature updates for Power BI, Sigma, and Tableau. For the other platforms, the latest public release material I found was either outside the Apr 13–27, 2026 window or limited to minor fixes that I excluded. (powerbi.microsoft.com [https://powerbi.microsoft.com/sv-se/blog/power-bi-april-2026-feature-summary/])
Looker
- No qualifying updates found in the last 14 days. In Google’s public Looker release notes, the surfaced entries I found were older, with no Apr 13–27, 2026 analyst-facing feature items visible. (docs.cloud.google.com [https://docs.cloud.google.com/looker/docs/release-notes?utm_source=openai])
Power BI
- Apr 22, 2026: In-report Copilot on Power BI mobile now supports open-ended follow-up chat against the current report, can generate AI-created visuals, includes citations back to report visuals, and adds voice dictation on iPhone/iPad. (powerbi.microsoft.com [https://powerbi.microsoft.com/sv-se/blog/power-bi-april-2026-feature-summary/])
- Apr 22, 2026: The modern visual defaults preview adds a base-theme switcher for updating or reverting report themes, plus preset canvas sizes for common aspect ratios. (powerbi.microsoft.com [https://powerbi.microsoft.com/sv-se/blog/power-bi-april-2026-feature-summary/])
- Apr 22, 2026: Card, button slicer, and list slicer visuals now support a fixed-size layout mode, so authors can specify exact pixel dimensions instead of auto-fitting items. (powerbi.microsoft.com [https://powerbi.microsoft.com/sv-se/blog/power-bi-april-2026-feature-summary/])
- Apr 22, 2026: The April modeling preview adds Direct Lake calculated columns/tables and user-context-aware calculated columns for scenarios like data translations. Microsoft says Direct Lake service rollout is still deploying over the next few weeks, so availability may lag the announcement. (powerbi.microsoft.com [https://powerbi.microsoft.com/sv-se/blog/power-bi-april-2026-feature-summary/])
Tableau
- Date note: Tableau’s public materials identify this as the April 2026 release, and Tableau was still promoting that release on Apr 25, 2026; the exact ship date is not shown on the main feature page, so inclusion in the 14-day window is a best-effort inference from Tableau’s own release surfacing. (tableau.com [https://www.tableau.com/blog/datafam-roundup-april-2026?utm_source=openai])
- April 2026 release: Tableau Next MCP is generally available, allowing MCP-compatible AI apps to query Tableau data and metadata through Tableau’s analytics engine. (tableau.com [https://www.tableau.com/products/new-features])
- April 2026 release: Inspector in Slack is in beta, sending natural-language metric-threshold alerts into Slack DMs and allowing follow-up questions from there. (tableau.com [https://www.tableau.com/products/new-features])
- April 2026 release: Tableau added agent-governance controls in Concierge: semantic-model scoping and page-filter visibility are GA, while Q&A Calibration is beta for testing and tuning agent responses. (tableau.com [https://www.tableau.com/products/new-features])
- April 2026 release: The Tableau App for Microsoft 365 is GA for Tableau Cloud and Server, letting users embed dashboard/Pulse snapshots in Word and PowerPoint and refresh them later. Tableau’s March 16 blog described Word/PowerPoint support as public preview, so GA status appears to be new in the April release. (https://www.tableau.com/products/new-feature
