## 2.1.8

- Updated TOC game version for midnight

## 2.1.7

### Fixed
- Added nil guards to AddMessage hooks (chat frames and Communities/Guild frames) to prevent crash if original handler is unexpectedly nil
- Added nil guard in SetItemRef wrapper to prevent silent click-drop when original handler is missing
- Wrapped ItemRefTooltip:SetHyperlink hook in existence check to prevent load-time crash on clients without ItemRefTooltip
- Fixed ItemRefTooltip:SetHyperlink error handling to always return instead of falling through when original handler errors
- Fixed misleading comment on string-type safety check that incorrectly referenced hyperlinks
- Fixed inconsistent indentation in AddMessage hook function body
