I was watching the great presentation from @marination of the updated E-Commerce features at the conference, and I wanted to check out the code. I assumed that the latest code would be on the develop branch, but it looks like, that for this feature it was only pushed to the version-13 branch.
Is this the case? If yes, is it a one time thing or it is usual, that features are only pushed to v13, so develop is lagging behind in some features, but is ahead in others? If yes, is there a list of such differences somewhere?
