I'm trying to get my development environment set up for the first time, but the newest version on the Rockit page is really old. Is there somewhere I can find a more up to date version? 

I tried installing the available version and then used the update feature within Rock, but it's forcing me to install each update one at a time. I'd really rather not have to manually install every version from 6.2 to 8.6 if I don't have to.
