Next, the number 41000. That could be a model number, a price point (unlikely, since it's free), or perhaps a version number. If it's free, that's a key point. Maybe it's a beta version given at no cost to users, encouraging them to test and provide feedback. The term "alpha" in software or product development usually refers to a preliminary stage before beta. So, "alpha free" might mean it's in the very early testing phase and offered for free in exchange for user input.
