v0.9.2 delivers major under-the-hood performance optimizations, significantly cutting down memory allocation and world-scan overhead through smart loot modifier caching and leaner recipe graph structures. Expect faster startup analysis passes, zero Netty buffer leaks, and a noticeably smoother profiling experience on heavy modpacks.

🔥 What's New for Modpack Developers

• Smart Loot Modifier Cache (LootOptimizer):
  • Adaptive Bypass: Probes loot tables during automated scans and identifies tables unmodified by modded hooks. Once verified, it completely bypasses redundant CommonHooks.modifyLoot passes, drastically cutting CPU overhead during UniversalLootSource and mob drop generation.
  • Configurable Sampling: Evaluates loot modifications dynamically across an initial 30-call sample threshold before marking tables as safe to skip.
• Modernized Recipe Serialization:
  • Migrated item cache serialization in RecipeGraphCache to vanilla's ItemStack.OPTIONAL_STREAM_CODEC (bumped cache format to VERSION = 5).
  • Yields faster disk serialization, cleaner cache loads, and tighter consistency with vanilla component data.

⚡ Performance & Stability

• Recipe Graph Memory Optimization (RecipeGraph): Replaced bloated ConcurrentHashMap structures with high-performance FastUtil collections (Reference2ObjectOpenHashMap, ObjectArrayList). This optimizes item lookups and substantially reduces memory overhead when indexing massive recipe registries.
• Resource Leak Prevention via RAII (Scope): Standardized lock acquisition, thread cleanup, and Netty ByteBuf release routines across AnalysisEngine, cache I/O, and ScanExecutor using an AutoCloseable scope pattern, eliminating edge-case buffer leaks on cancelled tasks or crashed workers.
• Context-Aware Log Silencing (LogFilter): Unified log interception into a scoped auto-closing filter. Silences known synthetic loot simulation noise (such as unsmeltable drops, missing enchantments, and DISTXFORM markers) without hiding real runtime errors.
• Null-Safe Component Matching (ItemStackIdentity): Relocated identity checks to core utilities and hardened stack comparisons against null references, preventing unexpected NPE crashes during item parsing.
• Internal Engine Refactoring: Streamlined reflection scanning in MachineReflectionScanner, extracted dynamic registry argument resolution in RecipeMetadata, and simplified path resolution algorithms in the machine controller scanner.
