This is a big resource pack update with a lot of important changes. At some point I stopped recording all the changes, so there won't be a detailed changelog.

Main points:
- Gave up curved upper stairs and 1/4 slabs. They're cool, but they don't mate well with the absolutely terrible vanilla lighting engine + cause a lot of problems for players who are used to vanilla building patterns or for custom worlds. 
These things will come back, maybe in a separate addon, but most likely as part of some mod support.
(By the way, this change will help raise fps).
Stairs and Slabs affected for: Cobblestone, Mossy Cobblestone, Cobbled Deepslate, Prismarine, Bricks, Nether Bricks, Red Nether Bricks, Sandstone, Red Sandstone.

- Full support for new textures for Armor Trims

- MANY mobs texture. (some still WIP, CEM still WIP)

- Support for 1.20 update, except GUI changes in 1.20.4 (Mojang, fkng stop making structural changes in minor versions)

- Sandstone and Red Sandstone rework - more interesting and detailed textures

- Wooden Planks rework (again)

- Many CTM fixes

- Done missing particles

- Done missing enviroment textures (clouds, snow, moon, etc)

- Many other small changes
