What does Shovel Knight Treasure Trove get me?

Ok thanks for answering my question. Why would anybody want to buy the campaigns seperately though? 

I'd assume because they're cheaper and that way you can pick and choose which ones you want to pay for... but for the price it is, it's more than worth buying Treasure Trove anyway!

So, I have the PS4 version, do I get all the expansions, or will there be more that I don't get?
