The version that causes problems for me is 3.3.004-324-g367f6b95

All modules are using a lot more cellular data but one in particular 
stands out. It's the one with the lowest wifi dBm but it's not *that* 
bad, but it makes me wonder if there is some kind of wifi power saving 
that's making wifi frequently unavailable causing cellular data usage 
(combined with something in this version that is 10X as chatty -- I 
suspect fixing this will get my usage back down).
