Great benchmarking tool and stability tester for overclockers.
Much of the FFT assembly code has been rewritten for better speed on newer CPU architectures. There are also many more FFT sizes supported. The net result is significantly faster test times for most users! To upgrade from version 25, simply exit Prime95, download the new version, and unzip the new version replacing the old version.
