### Added
  • Minecraft 26.3 support
### Added
  • Optional setting to replace the vanilla nether fortress with the mega fortress. It is off by default and can be toggled from the Moogs Structures config (in game, or in the config file). Changes apply when you reload the world.
  • While it is on, the mega fortress counts as a nether fortress: the "A Terrible Fortress" advancement, wither skeleton and blaze spawning on nether bricks, /locate and other mods' fortress checks all work inside it.
  • The mega fortress generates about as often as the vanilla fortress would have while it is replacing it, instead of at its usual rarity.
  • Its common chests use the vanilla nether fortress loot so items other mods add to fortress chests still show up.
  • Each structure in the Moog's Structures config screen now has a preview button.

### Fixed
  • The chains that the mega fortresses upper walkways are hanging from no longer have missing sections.
  • Paintings and item frames no longer disappear from the mega fortress and the dragon arena on certain mc versions.
  • The mega fortress's painting now displays properly on every supported version, and has become
a collage of smaller paintings rather than a single large one.
  • The large arena's vaults now give their intended rewards instead of generic trial chamber loot.
  • Enchanted books in the fortress library are now actually enchanted.
  • Armour found in the ruined fortress chests is now enchanted as intended.
  • The arena bowman and the pit vanguard no longer wear damaged armour.
  • The spawners in the medium houses were doing nothing and now spawn piglins as intended
  • Spawners in the large house and the nether brick ruins now draw from a mix of mobs
instead of always spawning the same one
  • Chests and barrels that gave identical loot in every world now roll their loot properly
  • The large crossing and the lower walkways in the mega fortress are no longer cut short
when they run into terrain
  • Every structure has been rebuilt for each Minecraft version it supports, fixing a range of
small visual and loading problems.

### Changed
  • Now requires Moog's Structure Lib **v3.3.0** or newer.

### Changed
  • Now requires Moog's Structure Lib **v3.3.0** or newer.
### Added
  • Mega Fortress** - A massive new nether fortress made up of 207 pieces and packed with loot, mobs and traps. This is our best structure yet across all Moogs structure mods! The mega fortress is made up of various towers with dungeons hidden beneath the lava. Bridges stretch out in all directions with stairs and towers leading to a second floor suspended from the roof with chains.
  • Dragon Arena** - A dragon skeleton sitting in lava lakes. Here you will find the most challenging mobs from the 3 new arenas and therefore, the best loot.
  • Large Arena** - A combat focused arena that is mostly buried beneath the surface. Here you will find plenty of spawners, vaults and trial spawners.
  • Small Arena** - While the easiest of the 3 arenas, don't take it lightly. There are still powerful mobs here protecting loot that's worth the visit.

Good luck!

### Changed
  • Now requires Moog's Structure Lib **v3.0.0** or newer.

# Changelog


## 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

## [2.0.4] - 2026-05-06

### Added
  • Empty barrels in nether structures now contain loot
  • Structures now spawn in modded nether biomes on Fabric and NeoForge.
  • Added direct support for Better Nether and Incendium biomes.

### Changed
  • Improved terrain blending for larger structures.

### Fixed
  • Fixed very small nether brick ruins not generating correctly due to a misconfigured template pool.
  • Replaced 1.21 blocks that don't exist in 1.20: copper trapdoors → iron trapdoors, crafter → crafting table, waxed oxidized copper bulb → shroomlight.


## [2.0.3] - 2024-01-12

  • Added new structures.
