And thats why I stopped using it. I hate alphas.

Were 7-Zip's alphas unstable for you or do you just hate the fact that you are using an alpha software? I haven't had any issues with the alpha versions.

What's up with this program and alphas? Last stable release was in 2010.

Yes, and what's the point in using a version nomenclature which states year and month of release when that's not actually taken in consideration after one release...
