@ -42,6 +42,10 @@ Breaking Changes:
Other Changes:
- Debug: Stack Tool: Added "Stack Tool" available in "Demo->Examples->Stack Tool", "Metrics->Tools",
or by calling the ShowStackToolWindow() function. The tool run queries on hovered id to display
details about individual components that were hashed to create an ID. It helps understanding
the ID stack system and debugging potential ID collisions. (#4631) [@ocornut, @rokups]
- Windows: Fixed background order of overlapping childs submitted sequentially. (#4493)
- IsWindowFocused: Added ImGuiFocusedFlags_NoPopupHierarchy flag allowing to exclude child popups
from the tested windows when combined with _ChildWindows.
