Minecraft wiki entry for After_Beta_1.8, associated text: The Fartherer Lands, without occlusion from any previous sets of Far Lands, generates a terrain that are stretched out to the extent that they are thinner and flatter than the Farther Lands, similar to transitioning Far Lands in Bedrock Edition. Due to how Fartherer Lands generates their terrain, the lands are reduced into flat panels, cuboids and strips of blocks (which was generating into some extent in Farther Lands, but exacerbated in Fartherer Lands). Because of this, Fartherer Lands marks the end of "Swiss cheese" terrain (solid wall and infinite tunnels) of both Far Lands and the Farther Lands.[3]
