I'm not sure if it's something I've missed on an update note, I've tried my best to read through and can't see anything when I updated but I was upgrading from 3.01 RC5 as I'd had a series of work going on that I didn't want to interupt. I've returned to 3.01 RC5 and dependencies for now and so far everything is working.
[EDIT: I will happily update again if you want me to test anything]
