To address this, we've added a new report-level setting that lets you restore the pre-July 2025 behavior for field parameters' expansion and collapse of hierarchy levels. By default, hierarchy levels remain persistent, but you can switch off this feature for a report using the Persist Hierarchy Level setting. The following examples are where to find it:
In the following example, Category is selected, and the Categories are expanded, so you can see values broken down by Year:
Power_BI_January_2026_Feature_Summary
Now, when you change the field parameter from Category to Class, what happens depends on the Persist hierarchy level setting. If it's on, the matrix remains expanded, keeping the Year column visible; If it's off, the matrix collapses and displays only values for Class. The following table provides a comparison showing both behaviors based on whether the toggle is enabled or disabled.
| On | Off |
To learn more about the toggle and its impact, refer to the documentation on Let report readers use field parameters to change visuals.
Improved Color Picker Experience in Power BI
Power BI report creators can customize colors in visuals with a theme color picker and custom color picker. We have added additional capabilities to this release.
This enhancement makes color customization more intuitive and efficient, helping you design reports with confidence and ease.
Learn more about color formatting your visuals in the Tips and tricks for formatting color in reports documentation.
Granular Reset Options in the Format Pane
Format pane reset to default quickly let’s report creators undo customizations made to a visual. With this release, you can now reset default with finer control, for a single formatting group in the format pane. This is in addition to the existing functionality of reset to default for the whole visual and each section of the format pane.

This enhancement delivers greater flexibility and usability, making it easier to fine-tune your report formatting with confidence.

New reports get updated styling and the Actions footer by default. Existing reports keep their previous customizations, and you can enable or disable the Actions footer anytime via the Format pane.
Modern visual tooltips in Power BI reports enhance usability and interactivity by allowing users to drill down, up, or through data directly from the tooltip Actions footer. These tooltips automatically adopt report theme colors, offer customization options, and provide updated styling by default for new reports, with flexibility to enable or disable the Actions footer as needed in the Format pane.
To learn more, refer to the Create Visual Tooltips documentation.
With this month’s release, that behavior has changed. In reports created from this release onward, columns are once again sized by default based on the content they contain. This makes tables and matrices more compact, easier to read, and better aligned with the actual data.
You can still manually adjust column widths, or use Grow to Fit to expand columns when needed. But by default, visuals now prioritize content-driven sizing, giving you cleaner and more predictable layouts right out of the box.
Here’s a before and after of the defaults:
| Before | After |
You can now seamlessly open and edit these models directly into the Power BI Service. However, note that semantic models with incremental refresh still cannot be downloaded as PBIX files, and you cannot use the Power Query editor when editing these models in the web experience.
To learn more about editing semantic models in the service, refer to the Edit semantic models in the Power BI service documentation.
Starting with this release, Power BI can be configured to respect GB18030‑2022 encoding using the UnicodeCharacterBehavior setting. This setting is set to CodeUnits by default. To ensure your model is compatible with GB18030-2022, you’ll need to execute a specific XMLA command to set UnicodeCharacterBehavior to CodePoints:<Alter AllowCreate="true" ObjectExpansion="ObjectProperties" xmlns="http://schemas.microsoft.com/analysisservices/2003/engine"> <Object> <DatabaseID>[your database id]</DatabaseID> </Object> <ObjectDefinition> <Database ....> <ID>[your model id]</ID> <Name>[your model name]</Name> <Language>[your language code]</Language> <ddl200:CompatibilityLevel>[your model compatibility level]</ddl200:CompatibilityLevel> <ddl200_200:StorageEngineUsed>[your storage engine]</ddl200_200:StorageEngineUsed> <UnicodeCharacterBehavior xmlns="http://schemas.microsoft.com/analysisservices/2025/engine/924/924">CodePoints</UnicodeCharacterBehavior> ... </Database> </ObjectDefinition> </Alter>
The UnicodeCharacterBehavior influences any DAX function that determines the length of a text string, which include FIND, LEFT, LEN, MID, REPLACE, RIGHT. These functions will exhibit different behaviors when working with text strings that contain Unicode characters.
Let's look at how this works in practice. Here’s a measure that uses LEN to calculate the length of a text string:
StringLength = LEN ( SELECTEDVALUE ( 'Table'[Column1] ) )
| UnicodeCharacterBehavior = CodeUnits (default) | UnicodeCharacterBehavior = CodePoints |
Notice how on the left each Unicode character has length 2, where on the right, each Unicode character has length 1.
To learn more, refer to the documentation.
PBIR will be activated by default in the Power BI service as part of a phased rollout, with full availability anticipated by the end of February. Beginning with the March release, PBIR will be set as the default format in Power BI Desktop.
PBIR is currently in Preview with an opt-out option. Switching to PBIR is the last step before its General Availability, planned for Q3 2026. Any issues found now will be prioritized and addressed. Any issues identified during this period will be prioritized and addressed by our support team.
We recommend preparing for this transition ahead of GA, as PBIR will be the only supported report format once it becomes generally available.
