Atlas

Atlas 0.2.0-alpha — Changelog

• Added ChunkNoiseSamplerMixin — density function evaluation now routes through the vectorized noise pipeline, enabling SIMD-accelerated terrain generation on Java 21
• Added DensityFunctionCompiler and VecNoiseRouter — full vectorized noise path active when jdk.incubator.vector is available
• Added ChunkyBatchModeMixin — Atlas batch mode now automatically activates when Chunky starts a generation task and deactivates when it finishes, maximising pre-generation throughput without manual intervention
• Fixed memory leak in HOCSArenaManager — off-heap budget now correctly decrements when region arenas are released, preventing silent fallback to on-heap memory during long pre-generation sessions
• Fixed unpooled direct buffer allocations in NIO2Backend — I/O now reuses pooled 1MB direct buffers instead of allocating on every read/write, significantly reducing GC pressure and JNI overhead
• Added physical-core-aware thread scaling — generation pool size now respects physical core count rather than logical thread count
• Fabric Loader requirement raised to >=0.16.7
