// 2026-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2026-01-19: DirectX11: Added 'SamplerNearest' in ImGui_ImplDX11_RenderState. Renamed 'SamplerDefault' to 'SamplerLinear'.
// 2026-01-19: DirectX10: Added 'SamplerNearest' in ImGui_ImplDX10_RenderState. Renamed 'SamplerDefault' to 'SamplerLinear'.
// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
// 2025-06-11: DirectX10: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
// 2025-05-07: DirectX10: Honor draw_data->FramebufferScale to allow for custom backends and experiment using it (consistently with other renderer backends, even though in normal condition it is not set under Windows).

Breaking Changes:
- Backends:
- Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. (#914)
This change allows us to facilitate changing samplers, in line with other backends. [@yaz0r, @ocornut]
- When creating your own descriptor pool (instead of letting backend creates its own):
- Before: need at least IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER.
- After: need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE.
+ IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
- When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
- Before: ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)
- After: ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)
- Kept inline redirection function that ignores the sampler (will obsolete).
- Vulkan: with the change above it is now possible to change the current Sampler during
rendering, by poking into ImGui_ImplVulkan_RenderState's SamplerCurrentDS. (#914)

- Tweaked assert triggering when first item height measurement fails, and made it

- DrawList:
- Made AddCallback() user data default parameter.
- Misc:
- Minor optimization: reduce redudant label scanning in common widgets.
- Added missing Test Engine hooks for PlotXXX(), VSliderXXX(), TableHeader().
- Backends:
- GLFW: added a Win32-specific implementation of `ImGui_ImplGlfw_GetContentScaleXXXX`
functions for legacy GLFW 3.2. (#9003)
- Metal: avoid redundant vertex buffer bind in `SetupRenderState()`, which leads
to validation issue. (#9343) [@Hunam6]

- SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()`
helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value
and this breaks scaling border size. (#9369)
- Examples:
- Update VS toolset in all .vcxproj from VS2015 (v140) to VS2017 (v141). The later is the
first that supports vcpkg. Onward we will likely stop testing building the library with VS2015.
- GLFW+Vulkan, SDL2+Vulkan, SDL3+Vulkan, Win32+Vulkan: reworked to create a descriptor pool with:

- IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.

- likewise io.MousePos and GetMousePos() will use OS coordinates.
If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos.
- 2026/04/22 (1.92.8) - Backends: Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler.
- When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
- When creating your own descriptor pool (instead of letting backend creates its own): need at least IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE + IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE descriptors of type VK_DESCRIPTOR_TYPE_SAMPLER.
- 2026/03/19 (1.92.7) - MultiSelect: renamed ImGuiMultiSelectFlags_SelectOnClick to ImGuiMultiSelectFlags_SelectOnAuto.
- 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)
