 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  2025-05-07: Vulkan: Load dynamic rendering functions using vkGetDeviceProcAddr() + try both non-KHR and KHR versions. (#8600, #8326, #8365)
 //  2025-04-07: Vulkan: Deep-copy ImGui_ImplVulkan_InitInfo::PipelineRenderingCreateInfo's pColorAttachmentFormats buffer when set, in order to reduce common user-error of specifying a pointer to data that gets out of scope. (#8282)
 //  2025-02-14: *BREAKING CHANGE*: Added uint32_t api_version to ImGui_ImplVulkan_LoadFunctions().
 //  2025-02-13: Vulkan: Added ApiVersion field in ImGui_ImplVulkan_InitInfo. Default to header version if unspecified. Dynamic rendering path loads "vkCmdBeginRendering/vkCmdEndRendering" (without -KHR suffix) on API 1.3. (#8326)

+Docking+Viewports Branch:

+- Backends: Win32: Viewports: fixed an issue when closing a window from
+  the OS close button (with io.ConfigViewportsNoDecoration=false) while
+  user code is discarding the 'bool *p_open=false output' from Begin().
+  Because we allowed the Win32 window to close early, Windows destroyed
+  it and our imgui window became not visible even though user code was
+  still submitting it.
+- Backends: SDLGPU3 for SDL3: added multi-viewport support. (#8573) [@Lekoopapaul]
+- Backends: SDL2, SDL3: revert updating monitors and work areas info every
+  frame. Only do it on Windows to detect task-bar resize until we get an
+  adequate event for it. (#8415, #8558)
+- Backends: SDL3: macOS: Fixed secondary-viewports not appearing on a different
+  monitor than the main viewport. Because SDL_SetWindowParent() seems to restrict it.
+- Backends: GLFW: Disable multi-viewports under Wayland (require GLFW 3.4). (#8587)
