Power BI Weekly

Issue #325 - 16th September 2025

FabCon Europe has started this week, and the announcements are flowing in: make sure you keep track of the Fabric blog and Power BI blog for all the latest. On the Power BI side, we've just received the Power BI September 2025 Feature Summary, the most interesting updates (IMHO) being: the new Enhanced DAX Time Intelligence (Preview), giving you a method to create custom calendars over tables & columns in your data model and benefit from streamlined time-intelligence DAX functions; the preview of DAX User Defined Functions (both of which were teased at FabCon Vegas earlier in the year); and possibly the most exciting announcement is that we can now Download PBIX of XMLA altered semantic models. That is, no more "This file can't be downloaded yet" warnings in the Power BI Service (unless you're using incremental refresh, I'm sorry to say). There are plenty more announcements in that blog, such as the GA of Editing semantic models in the Power BI Service and Live editing Direct Lake semantic models with Power BI Desktop, but I'll let you browse the rest! The only separate announcement this week (so far) is the Deprecation of Power BI Integration within SharePoint Lists and Libraries.

Aside from FabCon and announcements this week, Mim is back talking about Power BI, taking a First Look at Incremental Framing in Power BI, explaining how it works and providing some benchmark use-cases, and Dane Belarmino has shown how we can use the Matrix visual in order to Visualize an Entire Year with a Power BI Calendar Heatmap.
