Version 8.0 Auto Updater Tool?

I read on the blog https://www.premiumpress.com/blog/responsive-update-version-8-0/ that there will be a auto updater tool for version 8.0? is this tool a plugin? is it available now? If so where is it or how do I get it? I would like to update to the newest version for my auction theme. I now have the Version 6.6.7 responsive auction theme. I appreciate the help thank you!
