The twwFix addon restores several World of Warcraft API calls that were deprecated or removed in The War Within. By bringing back these functions, twwFix keeps older addons from erroring.

Key Features:

Restoring Common API Calls:
- Restores important API functions that were removed or deprecated in TWW, keeping older addons compatible with the latest game version.
- Notable API calls include:
  - GetAddOnMetadata: Allows addons to retrieve metadata again.
  - UnitAura, UnitBuff, UnitDebuff: Ensures compatibility for addons that track auras, buffs, and debuffs.
  - GetSpellTexture, GetSpellInfo: Keeps spell-related functions working for addons using spell visuals and data.
  - GetItemInfo, GetItemStats, GetItemIcon: Restores item-related APIs for addons that rely on item details and statistics.
Improved Compatibility With Older Addons:
- twwFix tries to keep older addons functional by restoring removed API calls and improving compatibility with game systems like items, spells, and buffs.
- This ensures you can keep using your older addons without needing rewrites.

However, it's not a fix-all and may not resolve every issue. It only restores the most commonly used API calls, so some older addons might still require manual fixes if the problem is elsewhere.
