• Item "Vial of the Sunwell" (ID:34471) will now be automatically cached by the client if it hasn't been seen, ensuring valid (~40y) information for C_UnitInRange (compactraidframe-3.3.5#30).
  
• C_UnitInRange function will now fallback to the original Blizzard UnitIsInRange (~36y) when playing on 3.3.5 Vanilla.
  
• AsyncCallbackSystemMixin:ItemEventListener has been rewritten, fixing numerous issues, also now less reliant on Private.Tooltip.
  
• Miscellaneous clean-up.
