// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2024-02-14: *BREAKING CHANGE*: Moved RenderPass parameter from ImGui_ImplVulkan_Init() function to ImGui_ImplVulkan_InitInfo structure. Not required when using dynamic rendering.
// 2024-02-12: *BREAKING CHANGE*: Dynamic rendering now require filling PipelineRenderingCreateInfo structure.
// 2024-01-19: Vulkan: Fixed vkAcquireNextImageKHR() validation errors in VulkanSDK 1.3.275 by allocating one extra semaphore than in-flight frames. (#7236)
// 2024-01-11: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size (#3957). Fixed MinAllocationSize handing (#7189).

@ -43,6 +43,8 @@ Breaking changes:
- Backends: SDL2: removed obsolete ImGui_ImplSDL2_NewFrame(SDL_Window*) signature which
was obsoleted in 1.84. Calling ImGui_ImplSDL2_NewFrame() is fine.
- Backends: Vulkan: Moved RenderPass parameter from ImGui_ImplVulkan_Init() function to
ImGui_ImplVulkan_InitInfo structure. Not required when using dynamic rendering. (#7308) [@shawnhatori]
- Backends: Vulkan: Using dynamic rendering now require filling the PipelineRenderingCreateInfo
structure in ImGui_ImplVulkan_InitInfo, allowing to configure color/depth/stencil formats.
Removed ColorAttachmentFormat field previously provided for dynamic rendering.
