The 8088 came out after the 8086. What advantages did it have over the 8086, if any?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
It was cheaper and allowed for overall cheaper system. Wikipedia has an exhausive article about the 8088:
In comparison, the 8086 has a 16-Bit data bus, which means that the accompanying system chips needed to be 16 Bits, which made them more complex and expensive.
There were some minor differences with the bus size and whatnot that made the 8088 less expensive to engineer interfaces for (e.g., for XT motherboards). The full details are explained here on these two pages:
I hope those two pages will answer your question completely.
