@ -74,11 +74,16 @@ Other Changes:
erroneously wrapped the value to one of the min/max edge. (#2024, #708, #320, #2075).
- DragFloat: Disabled using power curve when one edge is FLT_MAX (broken in 1.61). (#2024)
- DragFloat: Disabled setting a default drag speed when one edge is FLT_MAX. (#2024)
- Window: Resizing from edges (with io.ConfigResizeWindowsFromEdges Beta flag) extends the hit region
of root floating windows outside the window, making it easier to resize windows. Resize grips are also
extended accordingly so there are no discontinuity when hovering between borders and corners. (#1495, #822)
- Window, Inputs: Fixed resizing from edges when io.MousePos is not pixel-rounded by rounding mouse position input. (#2110)
- BeginChild(): Fixed BeginChild(const char*, ...) variation erroneously not applying the ID stack
to the provided string to uniquely identify the child window. This was undoing an intentional change
introduced in 1.50 and broken in 1.60. (#1698, #894, #713).
- BeginMenu(): Fixed menu popup horizontal offset being off the item in the menu bar when WindowPadding=0.0f.
- ArrowButton(): Fixed arrow shape being horizontally misaligned by (FramePadding.y-FramePadding.x) if they are different.
- Drag and Drop: Added GetDragDropPayload() to peek directly into the payload (if any) from anywhere. (#143)
- ImDrawList: Fixed AddConvexPolyFilled() undefined behavior when passing points_count smaller than 3,
in particular, points_count==0 could lead to a memory stomp if the draw list was previously empty.
