@ -44,6 +44,7 @@ Other Changes:
- Examples: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized
GL function loaders early, and help users understand what they are missing. (#2421)
- Examples: OpenGL3: Minor tweaks + not calling glBindBuffer more than necessary in the render loop.
- Examples: Vulkan: Added missing support for 32-bit indices (#define ImDrawIdx unsigned int).
- Examples: DirectX9: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects(). (#2454)
- Examples: FreeGLUT: Made io.DeltaTime always > 0. (#2430)
