so he must have went from 0 compression to as much as he could then, some say old one was 3.6 so that's a huge difference.It's weird. I extracted the archive from this smaller, new version, and the 1.8 3GB old one, and they are identical, other than this smaller 1.9 version having additional files. Seems the files are just very compressed, but the quality is more or less the same.
