@ -215,6 +215,7 @@ Other changes:
- Demo: Added "Drag and Drop -> Tooltip at target location" demo.
- Demo: Added "Layout -> Child Windows -> Manual-resize" demo. (#1710)
- Demo: Added "Layout -> Child Windows -> Auto-resize with constraints" demo. (#1666, #1395, #1496, #1710)
- Demo: Partly fixed "Examples -> Constrained-resizing window" custom constrains demo. (#6210) [@cfillion]
- Backends: Vulkan: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own
command-buffer to upload fonts. Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unecessary.
No need to call ImGui_ImplVulkan_CreateFontsTexture() as it is done automatically in NewFrame().
