# CUDA Python 11.8.0 Release notes

Released on October 3, 2022

## Highlights
- Support CUDA Toolkit 11.8
- Source builds allow for missing types and APIs
- Resolves source builds for mobile platforms
- Resolves [issue #24](https://github.com/NVIDIA/cuda-python/issues/24)

### Source Builds

CUDA Python source builds now parse CUDA headers located in $CUDA_HOME directory, enabling/disabling types and APIs if defined. Therefore this removes the need for CTK headers to have all types defined. By allowing minor variations, previous [11.7.1 mobile platform workaround](https://nvidia.github.io/cuda-python/release/11.7.1-notes.html#source-builds) is no longer needed.

It's still required that source builds use the latest CTK headers (i.e. “$CUDA_HOME/include” has latest CTK headers).
