I've been a Soylent drinker since 1.0. I've had 1.0, 1.1, 1.3 and 1.4.
The biggest formula change in terms of flatulence for me was 1.3 -> 1.4. They dropped the fiber substantially and replaced some of the oats (and most of the maltodextrin) with isomaltulose. I'm still gassy but it's nothing like 1.0/1.1, where I had uncomfortable levels of gas approximately 100% of the time.
