 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  2026-08-05: Vulkan: Added optional VK_EXT_descriptor_heap support via ImGui_ImplVulkan_InitInfo::DescriptorHeapInfo (app-owned Register*/UnRegister* callbacks). ImTextureID is a GPU descriptor device address (like DX12). Requires IMGUI_IMPL_VULKAN_HAS_DESCRIPTOR_HEAP (headers with VK_EXT_descriptor_heap).
 //  2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. (#9378)
 //  2026-04-22: *BREAKING CHANGE* redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. This change allows us to facilitate changing samplers, in line with other backends.
 //              - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler.
