@@ -41,6 +41,18 @@ HOW TO UPDATE?
 Breaking Changes:
 - Separator(): fixed a legacy quirk where Separator() was submitting a zero-height
   item for layout purpose, even though it draws a 1-pixel separator.
   The fix could affect code e.g. computing height from multiple widgets in order to
   allocate vertical space for a footer or multi-line status bar. (#2657, #9263)
   The "Console" example had such a bug:
      float footer_height = style.ItemSpacing.y + ImGui::GetFrameHeightWithSpacing();
      BeginChild("ScrollingRegion", { 0, -footer_height });
   Should be:
      float footer_height = style.ItemSpacing.y + style.SeparatorSize + ImGui::GetFrameHeightWithSpacing();
      BeginChild("ScrollingRegion", { 0, -footer_height });
   When such idiom was used and assuming zero-height Separator, it is likely that
   in 1.92.7 the resulting window will have unexpected 1 pixel scrolling range.
 - Combo(), ListBox(): commented out legacy signatures which were obsoleted in 1.90
   (Nov 2023), when the getter callback type was changed from:
      getter type:   bool (*getter)(void* user_data, int idx, const char** out_text)

+    deactivate/reactivate the item in order for e.g. IsItemDeactivatedAfterEdit()

 - Style:
  - Border sizes are now scaled (and rounded) by ScaleAllSizes().
  - When using large values with ScallAllSizes(), the following items thickness
    are scaled to integer amounts:
    - InputText Caret/cursor thickness. (#7031)
    - CloseButton() thickness.
    - TextLink() underline thickness.
    - ColorButton() border thickness.
    - Separator() thickness, via scaling newly added style.SeparatorSize. (#2657, #9263)
 - Clipper:
  - Clear `DisplayStart`/`DisplayEnd` fields when `Step()` returns false.
  - Added `UserIndex` helper storage. This is solely a convenience for cases where
    you may want to carry an index around.
 - Scrollbar:
  - Implemented a custom tweak to extend hit-testing bounding box when window is sitting
    at the edge of a viewport (e.g. fullscreen or docked window), so that e.g. mouse the
    mouse at the extreme of the screen will reach the scrollbar. (#9276)
 - Demo: fixed IMGUI_DEMO_MARKER locations for examples applets. (#9261, #3689) [@pthom]
 - Backends:
  - SDLGPU3: removed unnecessary call to SDL_WaitForGPUIdle when releasing
    vertex/index buffers. (#9262) [@jaenis]
  - WebGPU: fixed version check for Emscripten 5.0.0+.
  - WebGPU: removed support for Emscripten <4.0.10. (#9281) [@ypujante]
 - Examples:
  - Emscripten: added `tabindex=-1` to canvas in our shell_minimal.htm. Without it,
    the canvas was not focusable in the DOM, which in turn make some backends
    (e.g. pongasoft/emscripten-glfw) not receive focus loss events. (#9259) [@pthom]
-  - WGPU: fixed undefined behaviors in example code for requesting adapter
+  - Emscripten: fixed minor rendering issues with our HTML shell. (#9281) [@ypujante]
    - hidden small blue outline when canvas is focused on Chrome.
    - hidden scrollbar in Firefox.
  - Vulkan: added ImGui_ImplVulkan_PipelineInfo::ExtraDynamicStates[] to allow specifying
    extra dynamic states to add when creating the VkPipeline. (#9211) [@DziubanMaciej]

- - 2026/02/27 (1.92.7) - Commented out legacy signature for Combo(), ListBox(), signatures which were obsoleted in 1.90 (Nov 2023), when the getter callback type was changed.
+ - 2026/02/26 (1.92.7) - Separator: fixed a legacy quirk where Separator() was submitting a zero-height item for layout purpose, even though it draws a 1-pixel separator.
                         The fix could affect code e.g. computing height from multiple widgets in order to allocate vertical space for a footer or multi-line status bar. (#2657, #9263)
                         The "Console" example had such a bug:
                            float footer_height = style.ItemSpacing.y + ImGui::GetFrameHeightWithSpacing();
                            BeginChild("ScrollingRegion", { 0, -footer_height });
                         Should be:
                            float footer_height = style.ItemSpacing.y + style.SeparatorSize + ImGui::GetFrameHeightWithSpacing();
                            BeginChild("ScrollingRegion", { 0, -footer_height });
                         When such idiom was used and assuming zero-height Separator, it is likely that
                         in 1.92.7 the resulting window will have unexpected 1 pixel scrolling range.
 - 2026/02/23 (1.92.7) - Commented out legacy signature for Combo(), ListBox(), signatures which were obsoleted in 1.90 (Nov 2023), when the getter callback type was changed.
