3.0.0-alpha.2 — 2026-06-03

Fixed

• Accept MSL alpha versions in dependency constraint. Previously MNS required MSL >=3.0.0 which rejected 3.0.0-alpha.X per semver pre-release ordering, causing a Fabric Loader incompatibility error at startup. Constraint relaxed to >=3.0.0-alpha.1.

---

[3.0.0] - 2026-05-27

Adds the Mega Fortress and requires Moog's Structure Lib 3.0.0 or newer.

Added

• Mega Fortress - a large new nether structure assembled from a jigsaw layout: roofed and roofless corridors, crossings from small up to mega, forks, corners, staircases, a raised upper level, dedicated spawner rooms, and matching dead-end caps.
• Fortress garrison - themed inhabitants including fortress guards, archers, black guards, blaze sentinels, champions, and a warden of the keep.

Changed

• Now requires Moog's Structure Lib 3.0.0 or newer.
• Structure density - merged 5 groups of variant structures into shared weighted sets, reducing overall nether structure density.

---

[2.1.0] - 2026-05-22

Fixed

• Versioned structures now have a defined path for Minecraft 26.1–26.1.2, so the game stops logging "no version mapping matched" warnings and no longer falls back to an older structure template.

---

[2.0.4] - 2026-05-06

Added

• Empty barrels in nether structures now contain loot

Fixed

• Fixed very small nether brick ruins not generating correctly due to a misconfigured template pool
• Fixed chain blocks breaking in the giant skull, large house, smoking shrine, and train on 1.21.9+ (chain was renamed to iron_chain in that update)
• Updated piglins and piglin brutes in the medium houses to use the new 1.21 item format

---

[2.0.31] - 2026-02-01

Changed

• Updated for 1.21.11
