Concurrent Chunk Management Engine (Fabric)

• Enables ioSystem.replaceImpl by default
• Fixes thread count calculation for threaded worldgen

C2ME 0.2.0+alpha.8 for Minecraft 1.19 is released

This release improves overall performance and stability and fixes some bugs.

Changelog:

• Updates to 1.19
• Makes C2ME modular
• Optimizes sync loads a bit with priority system
• Implements chunkload cancellation mechanism
  • Makes teleporting lag less
  • Improves server shutdown times
  • .. and more
• Improves the handling of async chunkload requests on WorldGen threads to fix some rare deadlock issues
• Some micro-optimizations for math used by world generation
• Improves mobcaps consistency by filtering out mobs in no-tick chunks when calculating mobcaps
• Makes the new IO system implementation priority-aware
  (the new IO system can be enabled manually with ioSystem.replaceImpl in config)
• Client: The default max view distance is now determined by the JVM type and the memory allocated to Minecraft.

Notes:

• The calculation of default parallelism has been changed to be more reasonable.
  This means that some features may get re-enabled again by default if you are on a relatively lower-end devices

Fixes mobcaps with notickvd

Fixes POI not loading correctly in 22w19a

C2ME 0.2.0+alpha.7 for Minecraft 1.18.2 is released

This release improves overall performance and stability and fixes some bugs.

Changelog:

• Optimizes entity filtering in no-tick chunks to reduce lag when tons of entities in no-tick chunks
• Disables perlin noise vectorization with Vector API due to performance issues in JDK17
• Optimizes perlin noise with 25% speedup over vanilla
• Optimizes aquifer without changing vanilla behavior
• Rewrites chunk IO system focused on overall throughput
  (can be enabled manually with ioSystem.replaceImpl in config)
• Adds parallel scheduling to further reduce server thread load
  (can be enabled manually with asyncScheduling.enabled in config)
• Re-enabled noise caching in The End dimension when lithium is present
• Allows changing auto-save behavior
  Now defaults to saving chunks after ticking with periodical saving
  You can still use the original vanilla behavior or revert to pre-1.18 behaviors in config
• Fixes high cpu usage on scheduler thread when idle
• Fixes large lag in singleplayer creating world screen.
• Fixes compatibility issues with lithium 0.7.8 and later
• Fixes some crashes with certain datapacks and mods

Notes:

• The calculation of default parallelism has been changed to reduce stuttering in singleplayer worlds.
  This means that some features may get disabled if you are on a relatively lower-end devices.
  You can always re-enable them manually in config.
