cudajit 0.7.2 is now available in the opam repository. It’s a bug-fix release. Note that a salient missing feature of cudajit is CUDA graphs, if you want them I’m eager to add them, let me know!
Edit: API documentation
OCANNL 0.6.0 is also available in the opam repository. However, I only expect OCANNL to become usable at version 0.8 due to how I decided to prioritize things. The upshot is that the front-end should become pretty stable starting with version 0.7.
