• CUDA 13.1.1 is now available (https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html#). This updates CUDA 13 images to use it.

Contributes to rapidsai/build-planning#246

• RAPIDS has dropped Python 3.10 support in 26.04... this drops it here as well

Oops, thanks for catching the extraneous Python 3.10 builds here, @jameslamb !

Thanks James! 🙏

CI will be blocked until this cuGraph / cuDF incompatibility is fixed: rapidsai/cugraph#5415 (comment)

Oy sorry, I'd mean to click to update the branch, not merge the PR over failing CI 🙃

But anyway, I wanted to merge this to fix the forward merger, which has test failures on Python 3.10 only: #849

We can continue on that PR.
