Changelog

What's new in this build

Added

• Windows MMap prefetch via PrefetchVirtualMemory (FFM) in MadviseHelper.
  • Linux continues using posix_madvise (WILLNEED / DONTNEED).
  • Windows DONTNEED is intentionally a no-op; the OS manages page lifetime.

Changed

• Status now lists MMap prefetch on both Windows and Linux.
• Removed the old "Windows PrefetchVirtualMemory fallback" backlog item.
• Corrected output jar name to zeroseek-1.0.0.jar.
• MmapRegionIo debug log messages now use generic "MMap prefetch" wording.
• ZeroSeekConfig: added FUTURE comments for maxMappedBytes and chunkLoaderThreads.
• AsyncChunkService: added a FUTURE comment for the reserved loaderPool.

Removed

• Dead AsyncChunkService.prefetchChunk(ServerLevel, ChunkPos) method.
• Unused RegionFileVersion import in RegionFileMixin.
• Unused WeakReference import in EntityHibernation.

Fixed

• MadviseHelper: corrected Linux advice constants and separated platform logic into clean Linux / Windows / no-op paths.
• MadviseHelper: Windows PrefetchVirtualMemory binding now works correctly with MemorySegment.ofAddress(...) for the WIN32_MEMORY_RANGE_ENTRY layout.

Infrastructure

• Added this changelog file.
