 // CHANGELOG
-//  2025-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
+//  2026-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
 //  2025-11-26: macOS version can use MSL shaders in order to support macOS 10.14+ (vs Metallib shaders requiring macOS 14+). Requires calling SDL_CreateGPUDevice() with SDL_GPU_SHADERFORMAT_MSL.
 //  2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
 //  2025-08-20: Added ImGui_ImplSDLGPU3_InitInfo::SwapchainComposition and ImGui_ImplSDLGPU3_InitInfo::PresentMode to configure how secondary viewports are created.
