@ -36,10 +36,12 @@ HOW TO UPDATE?
Breaking Changes:
- Examples: Vulkan: Added extra parameter to ImGui_ImplVulkan_RenderDrawData(). Engine/app is
in charge of owning/storing 1 ImGui_ImplVulkan_FrameRenderBuffers per in-flight rendering frame.
(The demo helper ImGui_ImplVulkanH_WindowData structure carries them.) (#2461, #2348, #2378, #2097)
(The demo helper ImGui_ImplVulkanH_Window structure carries them.) (#2461, #2348, #2378, #2097)
- Examples: Vulkan: Added MinImageCount field in ImGui_ImplVulkan_InitInfo, required during
initialization to specify the number of in-flight image requested by swap chains.
(was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). (#2071, #1677) [@nathanvoglsam]
- Examples: Vulkan: Tidying up the demo/internals helpers (most engine/app should not rely
on them but it is possible you have!).
