Before I downloaded the update, you could just press and hold down on the block of inventory and let go after a few seconds to transfer it from your inventory to a chest and from the chest to your inventory. Now it will only transfer one item at a time. So if I have 64 cobble stones, I have to press it 64 times to transfer all of them, instead of just pressing and hold. The version I updated to was 1.2.9
don’t know if you need this as well
