5) Average price gets set to the "median feed"
I think this really means "the JSON-RPC field and the spot in the GUI that previously displayed the average price now display the median feed price but have not been relabeled." If this is, in fact, what it actually means, then I think we should relabel them before we drop the release candidate status.
BitShares has enough confusing, technical, somewhat poorly documented terminology as it is. There's absolutely no need to go re-defining terms like "average price" to mean something completely different from what people expect it to mean!
