- - 2018/05/03 (1.61) - DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", we are not using integers internally any more. 
+ - 2018/05/03 (1.61) - DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. 
                        If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
                        To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
                        If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. 
- - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", consistent with other functions. Kept redirection functions (will obsolete).

  - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
- - 2018/03/20 (1.60) - Renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some binding ahead of merging the Nav branch).
