Is this new? I just went to download it and it wants to replace my 2.0 version that I installed months ago. Does Opera Mini have automatic update or something?

I intstalled this on my Macbook mainly to open Stuffit files without haveing to install Sutffit Expander. Howerver, whenever I click on the archive, it just creates an empty folder and that is it. I tried a few files to know avail. Kinda a bummer, I was excited!
