Power BI Desktop Update - September 2019

You'll notice one of our exciting updates right away when creating new reports with the September update of Power BI Desktop, a new, modern default theme! Not only do we have a new default theme, but we've more than doubled the number of built-in theme options for your report. Thanks to an intern project, we're also releasing a frequently requested modeling feature: custom format strings. And of course, we have plenty of incremental improvements this month, with some performance improvements, more dynamic formatting options, updates to our personalized visualization pane, and more.
