@ -44,6 +44,8 @@ Other Changes:
- Fixed InputFloatX, SliderFloatX, DragFloatX functions erroneously reporting IsItemEdited() multiple
times when the text input doesn't match the formatted output value (e.g. input "1" shows "1.000").
It wasn't much of a problem because we typically use the return value instead of IsItemEdited() here.
- Fixed uses of IsItemDeactivated(), IsItemDeactivatedAfterEdit() on multi-components widgets and
after EndGroup(). (#2550, #1875)
- Scrollbar: Very minor bounding box adjustment to cope with various border size.
- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. (#2545)
Combine with RasterizerFlags::MonoHinting for best results.
