The update refactors chat interactions to the C_ChatInfo namespace (AceComm-3.0), modernizes hyperlink handling by using ChatFrameMixin:OnHyperlinkClick, and adds safe wrappers for message event filtering with ChatFrameUtil.AddMessageEventFilter. All changes were verified against the WoW UI source 2.5.5 to ensure compatibility and reduce risk for future patches. This work enhances reliability for players and simplifies ongoing maintenance by aligning with updated UI APIs.
