@ -57,6 +57,7 @@ Other Changes:
- Menus: MenuItem() and BeginMenu() are not affected/overlapping when style.SelectableTextAlign is altered.
- Nav: Disabled items are not candidate for default focus. (#211, #787)
- Disabled: disabled mode more consistently release active id if the active item got disabled. (#211)
- Disabled: disabled mode doesn't prevent Selectable() from looking selected. (#211)
- Fixed printf-style format checks on non-MinGW flavors. (#4183, #3592)
- Fonts: Functions with a 'float size_pixels' parameter can accept zero if it is set in ImFontSize::SizePixels.
- Fonts: Prefer using U+FFFD character for fallback instead of '?', if available. (#4269)
