You can download the archive from our Official Site.
You can also download it from our ModDB download page.
Download, unzip and try it. Then tell us if you think this release should be the final one.
Before posting your comments or report your problem, don't forget to check previous candidate release topic.
Also I just renamed the old "SG 1.1 beta testing" forum to Release so you can continue to check relevant topic and eventually open new topic for this RC.
