Internals: Fixed DragInt* default format string. InputScalar(), InputScalarN(), removed InputFloatN(), InputInt(). Note that DragInt2/3/4 will %f format strings will currently be broken. (#320, #643, #708, #1011)

@ -64,6 +64,7 @@ Other Changes:
- DragFloat, SliderFloat: Fixes to allow input of scientific notation numbers when using CTRL+Click to input the value. (~#648, #1011)
- DragFloat, SliderFloat: Rounding-on-write uses the provided format string instead of parsing the precision from the string, which allows for finer uses of %e %g etc. (#648, #642)
- DragFloat: Improved computation when using the power curve. Improved lost of input precision with very small steps. Added an assert than power-curve requires a min/max range. (~#642)
- DragFloat: The 'power' parameter is only honored if the min/max parameter are also setup.
- Nav: Fixed hovering a Selectable() with the mouse so that it update the navigation cursor (as it happened in the pre 1.60 navigation branch). (#787)
- Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439)
- 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)
