 Breaking Changes:
 
- - Removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor `io.OptResizeWindowsFromEdges=true` to enable the feature globally. (#1495)
-   The feature is not currently enabled by default because it is not satisfying enough.
  - Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
  - Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.

  - Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "...". (#1725)
+ - Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143).
  - IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211)
  - Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut] 
  - Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
  - Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987)
+ - Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive).  
  - Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)
