Latitude

Latitude 1.3.0 (MC 1.21.11)

Latitude 1.3.0 is a major upgrade from the 1.2.x line. It makes the world read more like a coherent climate system, while also improving stability and the first-run player experience.

Major worldgen improvements

• Reworked the climate-band model and related biome policy so latitude structure reads more clearly and more naturally.
• Reduced scattered confetti biome placement and improved biome contiguity across the world.
• Strengthened regional biome identity so key biomes feel more intentional and less thin, noisy, or patchy.
• Improved high-value cases like badlands and Pale Garden so they form more convincingly as real places.
• Restored missing or underrepresented biome outcomes in the regions where players would expect to find them.
• Smoothed climate handoff behavior so transitions feel less arbitrary and less visibly synthetic.

Player-facing improvements

• Refined the create-world and loading flow so starting a world feels more intentional and less abrupt.
• Implemented bespoke Create New World screen and world loading screens for a little extra polish.
• Fixed the excessively long first-time world creation/loading delay from the 1.2.x line, so first entry now feels much closer to normal vanilla startup.
• Improved first-entry behavior after world creation and after upgrading an existing save.
• Improved the first-run experience so the mod feels smoother and more finished from the moment you create or open a world.

Existing-world compatibility

• Existing 1.2.x worlds keep their legacy worldgen policy when opened in 1.3.0.
• The upgraded-save crash caused by a missing worldgen_policy bootstrap path was fixed.

Validation

• Structural audits passed.
• Invariant scan passed.
• Release integrity checks passed.
• Live upgrade and save smoke checks passed.
