@ -145,6 +145,8 @@ Other Changes:
Docking+Viewports Branch:
- Docking: Revert removal of io.ConfigDockingWithShift config option (removed in 1.83). (#4643)
- Docking: Fixed a bug undocking windows docked into a non-visible or _KeepAliveOnly dockspace
when unrelated windows submitted before the dockspace have dynamic visibility. (#4757)
- Viewports: Made it possible to explicitly assign ImGuiWindowClass::ParentViewportId to 0 in order
to ensure a window is not parented. Previously this would use the global default (which might be 0,
but not always as it would depend on io.ConfigViewportsNoDefaultParent). (#3152, #2871)
