I’m getting

```julia
WARNING: could not import Base._rangestyle into ArrayLayouts

```

when I run CI for my package. This is new for 1.8.0-rc3. What does this mean? Is there something I need to do?

The problem is that ArrayLayouts.jl is importing a private method from `Base`. Are you developing ArrayLayouts.jl?

Thanks, that explains ti.

I work on [SIAMFANLEquations.jl](https://github.com/ctkelley/SIAMFANLEquations.jl) and I don’t directly use ArrayLayouts. I use [BandedMatrices.jl](https://github.com/JuliaMatrices/BandedMatrices.jl) and it does.

@dlfivefifty, is this a serious problem?

Updated my packages, which I should have thought of in the first place, and the problem went away.
