Every month, Microsoft ships improvements to Power BI. But the April 2026 release feels different — it is one of those updates where several threads that have been developing for months finally come together into something you can actually feel in your daily workflow. Whether you’re a data analyst stitching together dashboards, a developer writing DAX, or a business user glancing at reports on your phone during a commute, this release has something meaningful for you.
So what are the new product updates for Power BI this month? In short: a much smarter Copilot on mobile, major jumps in modeling flexibility with Direct Lake, a modernised visual layer, and important deprecation notices that admins really should not ignore.

Let’s walk through each area properly.
Desktop version released: v2.153.910.0 on April 21, 2026. If you haven’t updated your Power BI Desktop yet, now is a good time to do that before diving into any of the new features below.
Copilot & AI Updates — Power BI Gets Conversational on Mobile
This is arguably the headline feature of the April 2026 Power BI new updates. Copilot has been slowly expanding its reach across the Power BI surface area, and this month it takes a big step forward on the mobile front.
In-Report Copilot Chat Now Available in Power BI Mobile Apps
For a while, Copilot on mobile was mostly a standalone experience. You could ask questions about a semantic model, but you couldn’t have a flowing conversation while you were inside a specific report. That changes now. With the April update, users can open a report on their phone or tablet, tap Copilot, and start chatting — asking follow-up questions, drilling into specific data points, or requesting a plain-language summary of what a chart is telling them.
This matters more than it sounds. A lot of real business decisions happen away from a desk — in a meeting room, between flights, or during a quick check before a call. Being able to interrogate a live report conversationally, on the device you already have in your hand, closes a gap that’s been there for some time.
Modern Visual Defaults and Theme Customisation Improvements
On the reporting side of Copilot and AI, Microsoft has introduced a base theme switcher inside the Customize current theme dialog. If you’ve been using custom themes and found that the newer modern defaults broke your visual styling, this gives you a clean escape — you can revert to the previous base theme and take your time updating. Equally, older reports can now be promoted to the latest modern defaults from within the same dialog, without rebuilding from scratch.
Copilot Chat in Reports (Mobile)
Conversational AI directly inside mobile reports. Ask follow-up questions, get summaries, and explore data in natural language — on the go.
Base Theme Switcher
Revert to older base themes or upgrade existing reports to the latest modern defaults — all from the Customize Theme dialog.
Canvas Preset Sizes
New common page sizes per aspect ratio in Canvas Settings. No more manual sizing for standard report dimensions.
Reporting Enhancements — Layouts, Slicers & Visual Labelling
April’s Power BI product updates deliver a set of reporting refinements that, individually, seem small — but together, they make the daily act of building and consuming reports noticeably smoother.
Fixed Size Layout for Card, Button Slicer & List Slicer Visuals
This one is a gift for anyone who has spent time wrestling with visuals that resize when the data changes. Card visuals, button slicers, and list slicers can now be set to a fixed size layout, giving you consistent, predictable spacing across all report pages regardless of the content inside them. It sounds like a small QoL improvement, and it is — but it’s the kind of thing that saves you ten minutes of repositioning per report.
Scatter Chart Autofit Markers and Axis Padding Controls
Scatter charts now include autofit markers so that data points don’t run over each other when the visual is small. Meanwhile, bar and column charts have gained axis padding controls, giving you tighter control over the white space between your chart bars and the axis lines. These are the sorts of formatting options that experienced report builders have been asking for, and they are now natively available without workarounds.
Preview Visual Labelling in the Visualizations Pane
A subtle but useful addition: visuals that are still in preview are now clearly labelled inside the Visualizations pane. Before, you had to hover or guess. Now, if you’re building a report and want to know whether a visual is production-ready or experimental, the pane tells you upfront. This is especially useful in enterprise settings where report governance matters.
Azure Maps Visual — Map Style Picker Sync
The Azure Maps visual now keeps its style picker in sync across interactions. Previously, the selected map style would sometimes reset when the report refreshed or when cross-filters were applied. That inconsistency is now resolved, making Azure Maps a more reliable choice for geospatial storytelling.
Power BI Modeling Updates — Direct Lake, DAX & User Context Awareness
This is where the April 2026 update really earns its place in the record books. Three preview features have landed in the modeling space that meaningfully expand what is possible in large-scale, enterprise-grade semantic models.
Direct Lake Calculated Columns & Tables
Direct Lake mode has been one of the most powerful additions to the Power BI / Microsoft Fabric story over the last couple of years. It lets you query data directly from a Lakehouse without importing it, delivering near-real-time freshness without the cost of duplication. Until now, one limitation was that you couldn’t add calculated columns or tables in Direct Lake mode — you had to fall back to Import mode to do that kind of in-model transformation.
That limitation is now being addressed. Direct Lake calculated columns and tables are in preview, and for teams managing large datasets, this is genuinely significant. You can now define model-level transformations and still keep the performance and freshness benefits of Direct Lake connectivity.
User Context-Aware Calculated Columns
Hand in hand with the above, Power BI is also previewing user context-aware calculated columns. This means your calculated column logic can now be influenced by who is viewing the report, not just what the underlying data says. If you are building personalised analytics experiences — where different users should see differently attributed metrics — this opens up possibilities that previously required complex row-level security workarounds.
DAX User-Defined Functions
DAX developers have been asking for this for a long time. User-defined functions in DAX allow you to define reusable logic blocks that can be called across multiple measures or calculated columns, much like functions in any proper programming language. Instead of copying and pasting the same complex DAX pattern five times across a model and then updating it in five places when business logic changes, you define it once. This is a meaningful step towards making DAX a more maintainable, scalable language for complex models.
Direct Lake Calc Columns
Add calculated columns & tables in Direct Lake mode — no more falling back to Import just for in-model transformations.
User Context Columns
Calculated columns that respond to the identity of the current viewer. Personalised analytics just became far simpler to build.
DAX User-Defined Functions
Write reusable DAX logic blocks. No more duplicating complex expressions — define once, call everywhere across your model.
New Visualizations — Third-Party Additions in April 2026
Two notable third-party visuals were added to the Power BI marketplace alongside this month’s updates:
- Date Picker by Powerviz brings a polished, calendar-style date selection experience to reports — a much cleaner alternative to the default date slicer for scenarios where the end user needs to pick specific dates rather than ranges.
- Drill Down Waterfall PRO by ZoomCharts extends the classic waterfall chart concept with interactive drill-down capability. For financial reporting and variance analysis, the ability to click into a waterfall bar and immediately explore the drivers behind a number is genuinely useful, and ZoomCharts have built a solid implementation here.
Pro tip: When using preview visuals, always label them clearly in internal reports. The new Visualizations pane labelling in this update helps — but communication with stakeholders about preview stability is still on you.

Deprecations in April 2026 — What Power BI Admins Need to Act On
No Power BI new updates summary would be complete without flagging the deprecations. April 2026 brings two that admins and developers should note.
Old File Picker Removed (SU04): The legacy file picker in Power BI Desktop is now gone. The updated file picker — introduced in preview in January 2026 — is now the only option. No action is needed, but teams with documentation or training materials referencing the old UI should update those assets.
Built-In Netezza ODBC Driver Deprecated: Microsoft is retiring the built-in Netezza ODBC driver in favour of the IBM Netezza ODBC driver which has been generally available for several weeks. Existing connectors do not need replacement, but you will need to install the new ODBC driver. Check your gateway data source settings if you connect to Netezza environments.
Wrapping Up — What the April 2026 Power BI Updates Mean for You
It’s worth stepping back and seeing what this update says about where Power BI is heading. The investments in Copilot are clearly maturing — we’re moving from novelty to genuinely integrated AI assistance across reporting and mobile. The modeling preview features, particularly Direct Lake calculated columns and DAX user-defined functions, suggest that Microsoft is serious about making Power BI’s semantic layer a first-class engineering environment, not just a business user’s tool.
If you are someone who keeps an eye on Power BI new updates each month, April 2026 is one to bookmark. Several of these previews will graduate to general availability over the coming months, and getting familiar with them now means you’ll be ahead when that happens.
