Rust 1.97 (releasing July 9, 2026) will raise the minimum baseline for the nvptx64-nvidia-cuda compilation target. The new minimums are PTX ISA 7.0 (requiring CUDA 11 drivers or newer) and SM 7.0 (Volta architecture or newer). GPUs with compute capability below 7.0 and CUDA 10-era drivers will no longer be supported. The change addresses existing compiler crashes and miscompilation bugs affecting older architectures, which date back to 2017 and are no longer actively supported by NVIDIA. Users targeting newer hardware and drivers should see no issues, but those specifying older -C target-cpu flags like sm_60 will need to update or remove them.
