// 2024-11-15: DirectX12: *BREAKING CHANGE* Changed ImGui_ImplDX12_Init() signature to take a ImGui_ImplDX12_InitInfo struct. Legacy ImGui_ImplDX12_Init() signature is still supported (will obsolete).
2728
// 2024-11-15: DirectX12: *BREAKING CHANGE* User is now required to pass function pointers to allocate/free SRV Descriptors. We provide convenience legacy fields to pass a single descriptor, matching the old API, but upcoming features will want multiple.

Other changes:
45+
46+
- ImDrawList: texture baked storage for thick line reduced from ~64x64 to ~32x32. (#3245)

- Examples: DirectX12: Reduced number of frame in flight from 3 to 2 in
48+
provided example, to reduce latency.

vkAcquireNextImageKHR() or vkQueuePresentKHR(). (#7825, #7831) [@NostraMagister]
51+
- Backends: DirectX12: Texture upload use the command queue provided in
