- Misc: Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769)
- Misc: Fix to allow compiling in unity builds where stb_rectpack/stb_truetype may be already included in the same compilation unit.
- Demo: Fixed Overlay: Added a context menu item to enable freely moving the window.
+- Demo: Added demo for DragScalar(), InputScalar(), SliderScalar(). (#643)
- Examples: Calling IMGUI_CHECKVERSION() in the main.cpp of every example application.
- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices).
- Examples: Allegro 5: Renamed bindings from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.

+ // The DragScalar, InputScalar, SliderScalar functions allow manipulating most common data types: signed/unsigned int/long long and float/double
