  - 2024/01/15 (1.90.2) - commented out obsolete ImGuiIO::ImeWindowHandle marked obsolete in 1.87, favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'.
  - 2023/12/19 (1.90.1) - commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter.
  - 2023/11/06 (1.90.1) - removed CalcListClipping() marked obsolete in 1.86. Prefer using ImGuiListClipper which can return non-contiguous ranges.
