Changelog

[Unreleased] — changes since v1.8.9-preview

Architecture

• Break Application::getInstance() singleton from GameHandler via GameServices struct
• EntityController refactoring (SOLID decomposition)
• Extract 8 domain handler classes from GameHandler
• Replace 3,300-line switch with dispatch table
• Multi-platform Docker build system (Linux, macOS arm64/x86_64, Windows cross-compilation)

Bug Fixes (v1.8.2–v1.8.9)

• Fix VkTexture ownsSampler_ flag after move/destroy (prevented double-free)
• Fix unsigned underflow in Warden PE section loading (buffer overflow on malformed modules)
• Add bounds checks to Warden readLE32/readLE16 (out-of-bounds on untrusted PE data)
• Fix undefined behavior: SDL_BUTTON(0) computed 1 << -1 (negative shift)
• Fix BigNum::toHex/toDecimal null dereference on OpenSSL allocation failure
• Remove duplicate zone weather entry silently overwriting Dustwallow Marsh
• Fix LLVM apt repo codename (jammy→noble) in macOS Docker build
• Add missing mkdir in Linux Docker build script
• Clamp player percentage stats (block/dodge/parry/crit) to prevent NaN from corrupted packets
• Guard fsPath underflow in tryLoadPngOverride

Code Quality (v1.8.2–v1.8.9)

• 30+ named constants replacing magic numbers across game, rendering, and pipeline code
• 55+ why-comments documenting WoW protocol quirks, format specifics, and design rationale
• 8 DRY extractions (findOnUseSpellId, createFallbackTextures, finalizeSampler, renderClassRestriction/renderRaceRestriction, and more)
• Scope macOS -undefined dynamic_lookup linker flag to wowee target only
• Replace goto patterns with structured control flow (do/while(false), lambdas)
• Zero out GameServices in Application::shutdown to prevent dangling pointers

[v1.8.1-preview] — 2026-03-23

Performance

• Eliminate ~70 unnecessary sqrt ops per frame; constexpr reciprocals and cache optimizations
• Skip bone animation for LOD3 models; frustum-cull water surfaces
• Eliminate per-frame heap allocations in M2 renderer
• Convert entity/skill/DBC/warden maps to unordered_map; fix 3x contacts scan
• Eliminate double map lookups and dynamic_cast in render loops
• Use second GPU queue for parallel texture/buffer uploads
• Time-budget tile finalization to prevent 1+ second main-loop stalls
• Add Vulkan pipeline cache persistence for faster startup

Bug Fixes

• Fix spline parsing with expansion context; preload DBC caches at world entry
• Fix NPC/player attack animation to use weapon-appropriate anim ID
• Fix equipment visibility and follow-target run speed
• Fix inspect (packed GUID) and client-side auto-walk for follow
• Fix mail money uint64, other-player cape textures, zone toast dedup, TCP_NODELAY
• Guard spline point loop against unsigned underflow; guard hexDecode/stoi/stof
• Fix infinite recursion in toLowerInPlace and operator precedence bugs
• Fix 3D audio coords for PLAY_OBJECT_SOUND; correct melee swing sound paths
• Prevent Vulkan sampler exhaustion crash; skip pipeline cache on NVIDIA
• Skip FSR3 frame gen on non-AMD GPUs to prevent driver crash
• Fix chest GO interaction (send GAMEOBJ_USE+LOOT together)
• Restore WMO wall collision threshold; fix off-screen bag positions
• Guard texture log dedup sets with mutex for thread safety
• Fix lua_pcall return check in ACTIONBAR_PAGE_CHANGED

Features

• Render equipment on other players (helmets, weapons, belts, wrists, shoulders)
• Target frame right-click context menu
• Crafting sounds and Create All button
• Server-synced bag sort
• Log GPU vendor/name at init

Security

• Add path traversal rejection and packet length validation

Code Quality

• Packet API: add readPackedGuid, writePackedGuid, writeFloat, getRemainingSize, hasRemaining, hasData, skipAll (replacing 1300+ verbose expressions)
• GameHandler helpers: isInWorld, isPreWotlk, guidToUnitId, lookupName, getUnitByGuid, fireAddonEvent, withSoundManager
• Dispatch table: registerHandler, registerSkipHandler, registerWorldHandler, registerErrorHandler (replacing 120+ lambda wrappers)
• Shared ui_colors.hpp with named constants replacing 200+ inline color literals
• Promote 50+ static const arrays to constexpr across audio/core/rendering/UI
• Deduplicate class name/color functions, enchantment cache, item-set DBC keys
• Extract settings tabs, GameHandler::update() phases, loadWeaponM2 into methods
• Remove 12 duplicate dispatch registrations and C-style casts
• Extract toHexString, toLowerInPlace, duration formatting, Lua return helpers
