- - 2023/05/15 (1.86.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin().
+ - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal. As the fields were added in 1.89 and expected to be left unchanged by most users, or only tweaked once during app initialization, we are exceptionally accepting the breakage.
+ - 2023/05/30 (1.89.6) - backends: renamed "imgui_impl_sdlrenderer.cpp" to "imgui_impl_sdlrenderer2.cpp" and "imgui_impl_sdlrenderer.h" to "imgui_impl_sdlrenderer2.h". This is in prevision for the future release of SDL3.
+ - 2023/05/22 (1.89.6) - listbox: commented out obsolete/redirecting functions that were marked obsolete more than two years ago:
+                           - ListBoxHeader()  -> use BeginListBox() (note how two variants of ListBoxHeader() existed. Check commented versions in imgui.h for reference)
+                           - ListBoxFooter()  -> use EndListBox()
+ - 2023/05/15 (1.89.6) - clipper: commented out obsolete redirection constructor 'ImGuiListClipper(int items_count, float items_height = -1.0f)' that was marked obsolete in 1.79. Use default constructor + clipper.Begin().
  - 2023/05/15 (1.89.6) - clipper: renamed ImGuiListClipper::ForceDisplayRangeByIndices() to ImGuiListClipper::IncludeRangeByIndices().
  - 2023/03/14 (1.89.4) - commented out redirecting enums/functions names that were marked obsolete two years ago:
