Just upgraded a client to 4.0.4 on a basically unmodified cart and it seems that the mini cart is not updating the total correctly. If you add a product to the cart, it won't update the price in the mini cart the total number of items seems to update though. Will update if you view the cart, but that's pointless. Anyone else seeing this? I'm going to send this off to X-cart and see what they say.
