Why don't you see Cíao anymore?
When looking for "cíao" (I don't know if the accent is correctly placed) all I could find is chao and other variations.
Why the sudden change?
Last year I was able to use cíao!

In Spanish the italian expression ciao is used as "chao". Some countries use "chau"
I am not really sure how it came to be that you were able to find "ciao" in the dictionary. I'd say that if it was there, it probably was a mistake. The correct word in Spanish, as pointed out by Farallon, is Chao. Chau is also used informally.
"Ciao", again as correctly pointed out by Farallon, is the Italian spelling of the expression.
