What is StataNow? First and foremost, StataNow is Stata. It is a continuous-release version of Stata that offers new features as soon as they are ready. StataNow is the result of our ongoing effort to deliver the best Stata—the most current Stata—to our users. StataNow provides access to new features as soon as they are certified ready by the development team. Those features are added to StataNow via free updates as soon as they are available. Thus, StataNow provides access to new features sooner. For instance, StataNow 19 contains features that will also be part of a future major release, Stata 20.
