Unified Xaero Worldmap

Changelog v1.0.0

First public release.

• Shared, server-side canonical map merged additively from every player's explored tiles.
• Live push of newly-explored tiles to all other online players, typically within seconds.
• Automatic catch-up sync on join, on dimension change, and periodically thereafter.
• All cave layers and all dimensions synced, not just the overworld surface.
• Tile-level merge granularity: nothing a client sends can delete or overwrite-away another player's data.
• Adaptive save interval — Xaero saves map regions faster only while another synced player is online, keeping the cost near zero when playing alone.
• Server-side configuration for sync rate, catch-up bandwidth, upload limits, and persistence interval.
• Automatic import of pre-release map data on first startup, with the original data preserved untouched in a backup folder.
• Singleplayer worlds are completely unaffected.
• Automated end-to-end test coverage across surface, cave, Nether, rejoin, and bulk-load scenarios, plus a unit test suite.
