FarLands

In 1.7.10 the Far Lands appeared at a fixed distance from the world origin, a glitch that was present by default until the Beta series. FarLands brings that behavior back for players who want it, and the mod is built for 1.7.10 on Forge.

Its configuration sets how far from spawn a player can start before reaching the Far Lands, so a server or single-player world can match the distance the author intends without traveling 12,550,820 blocks. The mod runs on the client and the server together, and both sides need it for the setting to apply.

The mod also contacts a version-check URL when it starts. Each request increments a counter on that address, which gives the author a rough count of how many times the mod has been requested. The author notes that the mod does not collect player data beyond that count, and that the author would like to know which modpacks include it. The code is open source under the MIT License.
