ChunkManager

Performance

• Much lighter chunk cost tracking - scanning is now spread out instead of sweeping every loaded chunk at once
• Removed a per-tick scan that ran constantly and did nothing
• Chunk unloading no longer stalls the main thread
• Faster startup and shutdown, no more delay when stopping the server
• Chunk border particles are far cheaper on your client and network
• Lower memory use overall, especially on worlds with many loaded chunks

Fixes

• Frozen chunks now genuinely stay loaded
• Entity limiter no longer removes tamed pets, villagers, leashed or named mobs, or item frames
• Portal preloading works on servers with custom world names
• Pre-generation saves progress as it runs, so a crash no longer loses your work
• Large pre-generation radii no longer spike memory on start
• Scheduled optimisation no longer skips its run time
• Menus open correctly on Folia

Improvements

• The dynamic radius thresholds in config.yml now actually apply
• Entity limiter has new protected-types and protected-items lists
• Chunk tickets are now used to hold teleport destinations
• Messages support hex colours with &#RRGGBB
• The Nether and The End are no longer excluded by default
