This pack aims to take the feel of 1.19 Minecraft, and put it into legacy versions, such as 1.8.9. All textures (blocks, mobs, items, etc.) are from the latest version. This makes the game look a lot better, because (in my opinion) the legacy textures are horrible. Because this texture pack is 16x, you shouldn't experience any extra lag.
Please comment other versions you would like to see backported to!
