@ -40,6 +40,7 @@ Breaking Changes:
If for some reason your time step calculation gives you a zero value, replace it with a dummy small value!
Other Changes:
- Added .editorconfig file for text editors to standardize using spaces. (#2038) [@kudaba]
- ImDrawData: Added FramebufferScale field (currently a copy of the value from io.DisplayFramebufferScale).
This is to allow render functions being written without pulling any data from ImGuiIO, allowing incoming
@ -58,6 +59,7 @@ Other Changes:
- Tabs: Removed ImGuiTabBarFlags_NoTabListPopupButton which was available in 1.67 but actually had zero use.
- Tabs: Fixed a minor clipping glitch when changing style's FramePadding from frame to frame.
- Tabs: Fixed border (when enabled) so it is aligned correctly mid-pixel and appears as bright as other borders.
- Style, Selectable: Added ImGuiStyle::SelectableTextAlign and ImGuiStyleVar_SelectableTextAlign. (#2347) [@haldean]
- Menus: Tweaked horizontal overlap between parent and child menu (to help convey relative depth)
from using style.ItemSpacing.x to style.ItemInnerSpacing.x, the later being expected to be smaller. (#1086)
- RadioButton: Fixed label horizontal alignment to precisely match Checkbox().
