How do you keep your Power BI skills current given how often it changes?

How you keep up: Power BI ships monthly, so the release blog is the primary source. Beyond that, the community — the Power BI community forums, SQLBI for DAX and modelling depth, and Guy in a Cube for practical walkthroughs. Most usefully, rebuilding something you already made using a new capability, because reading about a feature rarely tells you where it breaks.

How you filter:

• Modelling and DAX fundamentals repay study far more than new visuals. Filter context, relationships, and star schema design are what determine whether a report is correct and fast — and they change slowly.
• Preview features are not for production. They can change or disappear, and reports built on them can break.
• Does it solve a problem you have? A new visual type is irrelevant if your reports are slow because the model is wrong.

Note: Being able to say you deepened your understanding of a fundamental — filter context, or the difference between calculated columns and measures — rather than only collecting features, is the more impressive answer. Most Power BI problems in the wild are modelling problems, not feature gaps.
