GetNumStationAmmo(), GetStationAmmoInfo(index), GetNumStationSellableInventory(), GetStationSellableInventoryInfo(index) functions have been removed. The new way to iterate through player-owned station sellable inventory and ammo are as follows:

for itemid,iteminfo in StationSellableInventoryPairs() do
end

for ammoid,ammoinfo in StationPlayerAmmoPairs() do
end

I'm saying this because I've seen lua errors from plugins trying to reference the removed functions.
