@ -47,6 +47,7 @@ Other Changes:
- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. This is designed to allow CTRL+TAB between Tabs in the future. (#787)
- Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909)
- Window: Added global io.OptResizeWindowsFromEdges option to enable resizing windows from their edges and from the lower-left corner. (#1495)
- Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well.
- Drag and Drop: Fixed an incorrect assert when dropping a source that is submitted after the target (bug introduced with 1.62 changes
related to the addition of IsItemDeactivated()). (#1875, #143)
- Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143)
