Most updates are related to decorations. Earlier diorite, andesite, granite. Then terracotta. I saw on youtube talking about next update which will be again only related to decorations. The only good decoration for me which doesn't exists would be triangular (diagonal half or cube) blocks and ability to place cube blocks 45 degrees rotated. This would give much more possibilities for shape decorations.
Equipment for combat is still the same. We don't have new tools, nor new materials for tools, weapons, armors. The only metal we have is iron, we should be able to convert it to steal.
