- IO: Added io.ClearInputMouse() to clear mouse state. (#4921)
- Inputs: fixed using Shortcut() or SetNextItemShortcut() within a disabled block bypassing
the disabled state. (#7726)
- Windows: BeginChild(): fixed a glitch when during a resize of a child window which is
tightly close to the boundaries of its parent (e.g. with zero WindowPadding), the child
position could have temporarily be moved around by erroneous padding application. (#7706)
- TabBar, Style: added ImGuiTabBarFlags_DrawSelectedOverline option to draw an horizontal
line over selected tabs to increase visibility. This is used by docking.
Added corresponding ImGuiCol_TabSelectedOverline and ImGuiCol_TabDimmedSelectedOverline colors.
