Minecraft is so popular, and so dear to so many of its players, that I think I'd be terrified with each new update. The chance for potential upset seems enormous. In most instances, anyway. I'm looking at the patch notes for 1.10 - which adds polar bears, a new "Structure Block," and "A rare chance to find lonely trees in plains" among other things.
The structure block seems the fanciest addition in the sense that I don't understand what it does and would likely never use it. "This block allows map makers to store templates of structures and place them dynamically with the help of Redstone trickery," explains the above linked blog post, which suggests you might be able to build something, store it and then use redstone machinery to rebuild it in new places? I'm not sure!
I am sure about the polar bears however, which look lovely. In fact this update seems particularly high on loveliness. Aside from the lonely trees, there's also the news that "Some huge mushrooms can be even larger" and that there are now "Underground fossils made from bone blocks". It seems like a fair antidote to the recent combat update, which I know has rubbed some people up wrong, or the legal grey areas created by recent changes to the game's terms of service.
