The application version number applies to the software as a whole. It changes often as we update the application to add new features and ensure compatibility with the latest hardware. We recommend using the latest application version.

A benchmark version number—for example, Photo Editing Benchmark v1.0—is specific to a test. Benchmark version numbers change rarely and only when absolutely necessary to accommodate changes in third-party applications or bug fixes.
