"Skype is modern technology."
Translation:Скайп - це сучасна технологія.
Yes, новітній is a synonym.
If I have time, I can add it to alternative translations. I'd have to go through every exercise that has this word and add it.
Or, you can just remember that in this section you learned the word "сучасний" in the hints, and only use it :) You can freely use новітній when speaking with Ukrainians, though, of course!
