PBIX Is Not Going Away - But PowerBI Will Never Work the Same Again

"PBIX" packaged PowerBI reports into a single binary file, which worked well for individual authors but struggled at scale. "PBIR" replaces that model with a structured, project-based format that makes report changes explicit, improves collaboration and enables better governance. This shift doesn’t require immediate rewrites, but it does change how teams should think about building and managing Power BI reports long term.
