 - Drag and Drop: Fixed drop target highlight on items temporarily pushing a widened clip rect

   all columns. (#7049, #4281, #3272)
+- Menus: Tweaked hover slack logic, adding a timer to avoid situations where a slow vertical
+  movements toward another parent BeginMenu() can keep the wrong child menu open. (#6671, #6926)
+- Debug Tools: Added DebugFlashStyleColor() to identify a style color. Added to Style Editor.
+- Misc: Added IMGUI_USER_H_FILENAME to change the path included when using
+  IMGUI_INCLUDE_IMGUI_USER_H. (#7039) [@bryceberger]
+- 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]
 - Misc: Renamed some defines in imstb_textedit.h to avoid conflicts when using unity/jumbo builds
