@ -50,6 +50,7 @@ Other Changes:
after EndGroup(). (#2550, #1875)
- Fixed crash when appending with BeginMainMenuBar() more than once and no other window are showing. (#2567)
- Scrollbar: Very minor bounding box adjustment to cope with various border size.
- Style: Made window close button cross is slightly smaller.
- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. (#2545)
Combine with RasterizerFlags::MonoHinting for best results.
- ImFontGlyphRangesBuilder: Fixed unnecessarily over-sized buffer, which incidentally was also not
