Tableau Next: Visualisation enhancements
Drive more accurate business decisions with flexible, high-precision forecasting and real-time granular analysis. Tableau Next enhances your visualisations, allowing you to project revenue and KPIs across any mark type – from bars to doughnuts – without redesigning your dashboards. Instantly pinpoint peak performance patterns by drilling into real-time data at the minute level, with precise time-based insights reflected across every axis and tooltip.
Visualisation date-time support and forecasting for all mark types are generally available in Tableau Next.
Tableau Pulse: Enhanced Q&A improvements
Visualise the "Why" behind your metrics instantly with Enhanced Q&A insight briefs. Now, the most impactful visualisation is automatically rendered beneath its referenced insight, so you can see the data exactly as it's described. Plus, the ‘Analyse with AI' entry point is now available on mobile, so you can ask your own questions first from any device. Together, these updates streamline and clarify critical insights for all users.
Enhanced Q&A insight briefs with visuals are generally available in the Tableau+ edition of Tableau Cloud.
Enhanced Q&A custom homepage queries (mobile) are generally available across all Tableau Cloud editions.
Starburst connector JWT auth update
Unlock Starburst Galaxy connectivity with JWT auth for Galaxy servers. The modern auth method accelerates connection initialisation by eliminating validation queries, supports flexible server addressing through IP input and enables workload attribution through client tags. With JWT auth, users can analyse data across multiple sources faster and more securely.
The Starburst connector is generally available in Tableau Server, Tableau Desktop and Tableau Prep.
IP filtering self-service
Enhance site security by defining approved IP addresses or ranges to ensure only authorised locations can access your data. Administrators can now directly manage these restrictions within site settings to protect inbound traffic and maintain strict governance.
IP filtering self-service is generally available across all Tableau Cloud editions, with the exception of South Korea, Switzerland and India, which are scheduled to be added by the end of March
