BI-WEEKLY NEWS DIGEST

Latest news

	• DAX Studio 3.5.1 release The latest version of DAX Studio brings interesting new features to query plan and storage engine events. It also better supports user-defined functions and calendar-based time intelligence. Mandatory update! Mar 23, 2026 · Darren Gosbell
	• NYC Fabric Community - Kickoff Event A free community event on April 9 at 6PM in New York City, where Marco Russo will be presenting a session about DAX User-Defined Functions after Kim Manis (from Microsoft) recaps the news announced at Fabcon in Atlanta. This is also the kickoff event for the New York City Power BI and Fabric community. If you are in the area, spread the word, volunteers for future events are needed and welcome! Mar 20, 2026 · NYC User Group
	• Power BI March 2026 updates In this newsletter we have chosen to limit the news section because of the large number of announcements made by Microsoft at Fabcon in Atlanta. Direct Lake in OneLake is generally available, we have TMDL View in web modeling, and, last but not least, we have new features for DAX user-defined functions (UDF). Good news! Mar 18, 2026 · Microsoft
	• Fabric IQ: Plan or Planning? Microsoft must have seen "big tokens" try to take away its primacy of confusion in product names, so the Fabric IQ Plan (preview) is called Planning in Fabric IQ in the announcement. We are sure they will also change some caps before GA to make sure they keep the podium. We love this company! Besides, you should pay attention to this service: so many Power BI users will want it. Mar 18, 2026 · Microsoft
	• What is a semantic layer? One of the buzzword at Fabcon is "semantic layer". Is it a semantic model? Yes. Every vendor has different names for the same thing. This article is a good starting point to get more clarity. Mar 17, 2026 · Ruben Van de Voorde
	• DaxLib.SVG 1.0.1 Creating visuals using SVG in Power BI is cool, and it's simpler if you have this library that is now no longer in beta! Mar 20, 2026 · Jake Duddy
