@ -51,6 +51,7 @@ Other changes:
- Drag and Drop: Fixed drop target highlight on items temporarily pushing a widened clip rect
(namely Selectables and Treenodes using SpanAllColumn flag) so the highlight properly covers
all columns. (#7049, #4281, #3272)
- Debug Tools: Added DebugFlashStyleColor() to identify a style color. Added to Style Editor.
- Misc: Added extra courtesy ==/!= operators when IMGUI_DEFINE_MATH_OPERATORS is defined.
- Misc: Fixed text functions fast-path for handling "%s" and "%.*s" to handle null pointers gracefully,
like most printf implementations. (#7016, #3466, #6846) [@codefrog2002]
