@ -122,6 +122,8 @@ Other changes:
- Windows: Layout of Close/Collapse buttons uses style.ItemInnerSpacing.x between items,
stopped incorrectly using FramePadding in a way where hit-boxes could overlap when
setting large values. (#6749)
- TabBar, Style: added style.TabBarBorderSize and associated ImGuiStyleVar_TabBarBorderSize.
Tweaked rendering of that separator to allow thicker values. (#6820, #4859, #5022, #5239)
- InputFloat, SliderFloat, DragFloat: always turn both '.' and ',' into the current decimal
point character when using Decimal/Scientific character filter. (#6719, #2278) [@adamsepp]
- ColorEdit, ColorPicker: Manipulating options popup don't mark item as edited. (#6722)
