Hi,  
I’ve just realized that CuArrays seems to be deprecated in favour of CUDA.jl.  
Now I tried

```julia
add CUDA

```

and failed, but did work

```julia
add CUDA.jl

```

why the .jl? Anyway it is not critical… Still I have lots of code lines written  
with CuArrays, and was wondering if sentences like

```julia
CuArrays.zeros(100)

```

will cease to work. If that was the case I’ll be in big trouble…  
Hopefully somebody can explain the status of things now?

Thanks in advance,

Ferran.

`add CUDA` should work, just tried it locally. I would try it in a fresh project and post any errors here/on GitHub if you still run into them.

I believe most all of the CuArrays interface should be exported under the CUDA namespace now. Porting should be a simple find-and-replace (e.g. just tested `CuArrays.zeros` → `CUDA.zeros`)

You can safely get rid of CuArrays, CUDAnative, CUDAdrv and CUDAapi now! See [this announcement](https://discourse.julialang.org/t/psa-cuda-jl-replacing-cuarrays-jl-cudanative-jl-cudadrv-jl-cudaapi-jl-call-for-testing/40205).
