When I run the tests of KiteModels.jl I get the warning:

```julia
┌ Warning: Using a `Bool` for keyword argument `autodiff` is deprecated. Please use an `ADType` specifier.
│ caller = _process_AD_choice(ad_alg::Bool, chunksize::Val{0}, diff_type::Val{:forward}) at misc_utils.jl:147
└ @ OrdinaryDiffEqCore ~/.julia/packages/OrdinaryDiffEqCore/3Talm/src/misc_utils.jl:147

```

In which package can this be fixed?

If you run with `depwarn=error` you will get stacktraces (if the OrdinaryDiffEq side implemented the warning correctly). That said, it looks like the problem is in KiteModels: [KiteModels.jl/src/KiteModels.jl at 37536ee062b65eed57b2e89b168d1d26c35a61e0 · ufechner7/KiteModels.jl · GitHub](https://github.com/ufechner7/KiteModels.jl/blob/37536ee062b65eed57b2e89b168d1d26c35a61e0/src/KiteModels.jl#L558) this should now be `DImplicitEuler(autodiff=AutoFiniteDiff())` etc…

I tried that, and I get:

```julia
ERROR: LoadError: UndefVarError: `AutoFiniteDiff` not defined

```

Any idea?
