Updating to Newest Version of Sylius - sylius

Question

Looking at the recent changes to Sylius and the new interface, as well as the Roadmap which has beta 1.0 out in November, I'd love to update my development project to the newest version, and continue updating until the beta in November, at which point I'll stop and use this as the version which I finish development on. I see an old post here on SO about updating Sylius, but it's from 2014 and almost every package referenced is out of date. I'm looking for a fresh copy of a recent composer.json requirements list, or instructions on the easiest way to get my project up to date (without a total reinstall) so I can keep up until Beta 1.0. I'll attach my current composer.json require list, in case it's pertinant. Thanks!
