DEPRECATED

This version is missing a few key features of the 1.3.0 update, lost during the porting process. Recommended to use the later 'hotfix' version.

Latitude 1.3.0 for Minecraft 1.21.1

This is a backport of Latitude 1.3.0 to Minecraft 1.21.1, bringing the current climate/worldgen improvements and bespoke UI work to the older 1.21.1 line.

Highlights

• Added support for Minecraft 1.21.1.
• Added Latitude’s bespoke create-world flow for the 1.21.1 version.
• Improved first-world loading behavior.
• Fixed a major first-join stall that could leave players staring into the void for a long time after the loading screen.
• Removed the fake second Latitude “Loading terrain / Preparing the frontier” overlay phase.
• Aligned in-game latitude zone titles with the canonical five-band climate model.
• Added compatibility fixes for 1.21.1 worldgen/snow-guard behavior.
• Removed a newer-version Pale Garden tag reference that does not exist in Minecraft 1.21.1.

World generation and loading

• Fixed a spawn-selection issue where Latitude could force too much chunk generation during player join.
• Fresh world entry should now feel much closer to normal Minecraft loading speed.
• Preserved Latitude’s latitude-driven climate behavior while adapting the port to the 1.21.1 runtime path.
• Added gated biome-cost diagnostics for future performance debugging without changing normal gameplay behavior.

UI and player experience

• Added the bespoke Latitude create-world screen and world-launch flow.
• Added a planisphere-style visual preview in the create-world experience.
• Cleaned up loading-screen handoff behavior so Latitude no longer shows a second branded terrain-loading screen over an already-entering world.
• Zone-title logic now follows the canonical Latitude band system more consistently.

Known notes

This is a backport of the 1.3.0 line, so some content available in newer Minecraft versions is not present in 1.21.1. The release has been cleaned so it no longer references Pale Garden in the 1.21.1 biome tags.
