Looks like it’s the 2015 discovery:
It was a handful of extra lines that described the Cedar Forest being much more lively and noisy, acting like a whole royal court, than previous versions. It also showed that the whole tablet was much more recent than previously thought.
Pretty sure it’s this one from 2015
