 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
+//  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)
 //  2025-01-09: Vulkan: Added IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE to clarify how many image sampler descriptors are expected to be available in descriptor pool. (#6642)
 //  2025-01-06: Vulkan: Added more ImGui_ImplVulkanH_XXXX helper functions to simplify our examples.
 //  2024-12-11: Vulkan: Fixed setting VkSwapchainCreateInfoKHR::preTransform for platforms not supporting VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR. (#8222)
