+- Internals: changed/inverted ImGuiItemFlags_SelectableDontClosePopup (default==false) to

   - Added ImGuiItemFlags_NoNav to disable any navigation and focus of items. (#787)
   - Added ImGuiItemFlags_NoNavDefaultFocus to disable item being default focus. (#787)
   - Added ImGuiItemFlags_ButtonRepeat to enable repeat on any button-like behavior.
-  - (previously in imgui_internal.h)
+  - Added ImGuiItemFlags_AutoClosePopups to disable menu items/selection auto closing parent popups.
+    Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().

 - Debug Tools: Added IMGUI_DEBUG_LOG(), ImGui::DebugLog() in public API. (#5855)
   Debug log entries add a imgui frame counter prefix + are redirected to ShowDebugLogWindow() and
   other configurable locations. Always call IMGUI_DEBUG_LOG() for maximum stripping in caller code.
