 # This repository is actively being fixed and maintained by Bluewhale.
 
 ## Changelog
+- **Fix:** Fixed global ID Lua 5.0 varargs crash across all Tooltip functions.
 - **Fix:** Fixed a Lua 5.0 syntax error in `AceConfigDialog-3.0.lua` where the `#` length operator was used instead of `table.getn`, preventing ElvUI_Config from loading.
 - **Fix:** Fixed nil ID formatting crash in Tooltip's SetHyperlink.
 - **Fix:** Removed implicit `arg` table memory leaks in high-frequency oUF element updates by replacing varargs (`...`) with static parameters.
