Has :auto been removed as an argument to DataFrame? It no longer seems to work:
```julia
> DataFrame([1 2; 3 4], :auto)
ERROR: MethodError: no method matching DataFrame(::Matrix{Int64}, ::Symbol)

Huh, weird. I’m can run this on my machine using DataFrames v1.6.1
```julia
julia> DataFrame([1 2; 3 4], :auto)
2×2 DataFrame
Row │ x1 x2
│ Int64 Int64
─────┼──────────────
1 │ 1 2
2 │ 3 4
```
What version of DataFrames do you have?

Perhaps that is my problem: Here’s the result of `] status DataFrames`:
Status `~/.julia/environments/v1.9/Project.toml`
⌅ [a93c6f00] DataFrames v0.21.8
Yours is a major version ahead of mine. This is strange, because I updated the packages
`(] up)` only yesterday. It was after that update that the problem appeared.

Ah maybe there is another package that is preventing DataFrames from updating because of a conflict.

The arrow symbol next to DataFrames in the status output indicates that about dependency is preventing it from upgrading to a newer version.

Yes, DataFrames v0.22 is **really** old. You can see what’s holding it back with `status --outdated`. For a contrived example, you can see here that this very old version of CSV is what’s holding back DataFrames:
```julia
(@v1.10) pkg> status --outdated
Status `~/.julia/environments/v1.10/Project.toml`
⌃ [336ed68f] CSV v0.7.10 (

It appears that I added a package that required many other packages to downgrade. There was no warning about this–at least none that I recall. Is there a setting that will cause Pkg to warn before downgrading in this fashion?

There’s no specific warning but you will see downgraded packages highlighted in purple:
