Lecterns have the books & carpet removed, so you can use them in more situations!
The most notable change, would be the Yellow Glazed Terracotta! Made to fit honey & hives! More like it soon! Nether Brick & Red Nether Brick also have had their textures slightly changed, to match most other bricks just a tiny bit better.
New grass, and soul sand textures! Perfect for little rivers like this! Grass also has little things under it, so you don't dig into the surface unexpectedly when building underground.
Iron bars, blocks, kelp, coal & campfires, improved for building!
Paper lanterns! Any lanterns in birch boimes, jungle biomes, or gravel mountains, will become a Paper lantern!
Nuggets replaced with Coins, and ingots now actually match them!
Lanterns have a new model, again inspired by the beautiful Excalibur!
Not really, but it's really rare! Rose variations, with red being most common, then pink & red, then all pink, then last, pink and white!
I saw the Sign! Signs are now updated to match planks, and be smoother for text.
Overused joke, I know, but doors now have fancy textures! As well as trapdoors, better for building!
Granite, Diorite, and Smooth Stone have better textures, and Andesite's also got slabs to match, even though no texture change.
Composter sides no longer have dirt! Petrified wood uses Composter palette! Farmland now has sides to match the top! All the little details.
