Performance and stability update for WoW 3.3.5a.

Highlights

• improved Lua Phase 2 runtime discovery across world transitions and reloads
• added string.match partial fast path for safe common patterns
• retained hardened Lua VM internals:
  • per-VM string interning cache
  • validated cache hits
  • SEH-guarded concat fast path
• improved long-session smoothness and addon-heavy runtime behavior
• preserved public-safe defaults by keeping historically risky features disabled

Included optimizations

• mimalloc CRT and Lua allocator replacement
• adaptive multi-mode Lua GC
• string table pre-sizing
• Lua fast paths for common string, math, and conversion functions
• combat log optimization
• GetItemInfo cache
• QPC-based timer improvements
• file I/O, networking, and synchronization improvements

Notes

• public-safe builds still keep MPQ memory mapping, UI widget cache, GetSpellInfo cache, dynamic unit API caching, and GlobalAlloc fast path disabled
• custom or HD clients may still behave differently from stock 3.3.5a clients, especially in multi-client setups

Recommended setup

Use together with !LuaBoost for the best overall Lua and addon-side results.
