     and relied on ambiguously defined design. Use 'SetNextItemAllowOverlap()' before item instead.
   - Renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap'.
   - Renamed 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'
-  - IsItemHovered: Changed behavior to return false when querying an item using AllowOverlap mode
-    which is being overlapped. Added ImGuiHoveredFlags_AllowWhenOverlappedByItem. (#6512, #3909, #517)
-  - Selectable, TreeNode: When using ImGuiSelectableFlags_AllowOverlap/ImGuiTreeNodeFlags_AllowOverlap
-    and holding item held, overlapping widgets won't appear as hovered. (#6512, #3909)
-  - Most item types should now work with SetNextItemAllowOverlap(). (#6512, #3909, #517)
-  - Fixed first frame of an overlap highlighting underlying item if previous frame didn't hover anything.
   - Kept redirecting enums (will obsolete).
 
 Other changes:
 
 - Tooltips/IsItemHovered() related changes:
-  - IsItemHovered: Added ImGuiHoveredFlags_Stationary to require mouse being
-    stationary when hovering a new item. Added style.HoverStationaryDelay (~0.15 sec).
-    Once the mouse has been stationary once the state is preserved for same item. (#1485)
-  - IsItemHovered: Added ImGuiHoveredFlags_ForTooltip as a shortcut for pulling flags
-    from style.HoverFlagsForTooltipMouse or style.HoverFlagsForTooltipNav. (#1485)
-    - style.HoverFlagsForTooltipMouse defaults to ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort
-    - style.HoverFlagsForTooltipNav defaults to ImGuiHoveredFlags_NoSharedDelay | ImGuiHoveredFlags_DelayNormal
   - Tooltips: Added SetItemTooltip() and BeginItemTooltip() functions.
     They are shortcuts for the common idiom of using IsItemHovered().
     - SetItemTooltip("Hello")   == if (IsItemHovered(ImGuiHoveredFlags_Tooltip)) { SetTooltip("Hello"); }
     - BeginItemTooltip()        == IsItemHovered(ImGuiHoveredFlags_Tooltip) && BeginTooltip()
-    The newly added ImGuiHoveredFlags_Tooltip is meant to standardize mouse hovering
-    delays and rules for a whole application.
-    The previously common idiom of using 'if (IsItemHovered()) { SetTooltip(...); }' won't
-    use delay or stationary test.

   - Tooltips: Tweak default offset for non-drag and drop tooltips so underlying items
     isn't covered as much. (Match offset for drag and drop tooltips)
   - IsItemHovered: Tweaked default value of style.HoverDelayNormal from 0.30 to 0.40,
     Tweaked default value of style.HoverDelayShort from 0.10 to 0.15. (#1485)

 - Combo: Made simple/legacy Combo() function not returns true when picking already selected item.
   This is consistent with other widgets. If you need something else, you can use BeginCombo(). (#1182)
