[1.15.2-1.0.6]

I consider the mod finished. I don't think there will be new features in the future.

Added

• Trapdoor variant for most of the vanilla blocks. To not interfere with vanilla recipes, trapdoor recipes from this mod are like this :
  ###
...
###
  Where # is the block you want convert in trapdoor (. is empty).
• Grass Path Slab, Stairs, Fence, Wall and Trapdoor
• Log and Wood can be stripped to get the stripped version of the block. Work with stairs, slabs, fences, walls and trapdoors.
• Secret advancements
• You can convert Coarse Dirt Blocks to Dirt Blocks with a Hoe.
• Grass Block and Mycelium Block variants can spread to all Dirt Blocks.
• Iron Ore Stairs & Wall blasting recipe

Changed

[1.15.2-1.0.5]

Added

  If you have the mod Patchouli in you modpack, a book which describe some recipes/loot_tables from Vanilla Extension will be possible to craft (book+stick).
  Patchouli is not required to launch my mod. It is only required if you want the guide book.
• Farmland Slab & Farmland Stairs.
  You can have them by tilling grass/dirt slab/stairs crops on Farmland Stairs are kinda glitchy, but I can't really do something for it.

Changed

• better textures for Grass Block Slab & Mycelium Slab. The side of the block is now aligned like normal block.
• recipes for plank walls (like oak_plank_wall) don't conflict with trapdoors anymore. The recipes are like :
  .#.

  Where # is a plank (. is empty).
  And that give 7 walls.
