@ -60,6 +60,8 @@ Breaking Changes:
See https://github.com/ocornut/imgui/issues/3361 for all details.
Kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar().
For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used.
- DragInt, DragFloat, DragScalar: Obsoleted use of v_min > v_max to lock edits (introduced in 1.73, this was not
demoed nor documented much, will be replaced a more generic ReadOnly feature).

- if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiDragFlags_Logarithmic or ImGuiSliderFlags_Logarithmic flag to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.

- obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiDragFlags_ReadOnly internal flag in the meantime.
- 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete).
- 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
