The last update (Hearth and Home) did make significant changes and added a number of things. What your friend is saying is it didn't add new biomes or bosses. If they're telling you that the H&H update didn't add any content then they are clearly only looking for progression beyond the Plains, which hasn't been added yet. Many players are whining about that because the only "update" they want is for progression so they can "beat" the game. While this can be an "achiever" game, if that's your only preference then maybe you should just wait for the game to be officially released. But if you like exploration, crafting and base building, then it's already a pretty good game which will only get better as more updates come out. For the amount of game play you can get for the EA price, it's well worth it. Try it yourself and form your own opinion, relying on the biased opinions of others takes your own objectivity out of the equation.
