Personally, I kinda liked how it is… We can download the more stable releases if you want, or you can download ‘preview’ releases when they are avail, which just like they are called, are preview releases to give you an idea of whats to come(and help Epic with bug fixes so YOU get to help and let them know your bugs, to help make the stable release, well more stable) You don’t have to download the preview ones 
Either way, keep rockin’ Epic, you guys are great, love the new stuff(I do tend to work from either promoted or master branch though)
