CompatHelper submitted a PR to my package to allow the latest version of Symbolics, but [the build](https://github.com/moble/PostNewtonian.jl/actions/runs/10414493180/job/28862776448) is failing for reasons that I just don’t understand.

With the PR [my package (PostNewtonian)](https://github.com/moble/PostNewtonian.jl/pull/57/files) lists in its `compat` section

```
DataInterpolations = "5.1, 6"
Symbolics = "5.25, 6"

```

(among others). DataInterpolations v6.1.0 lists

```
Symbolics = "5.29, 6"

```

(among others), and Symbolics v6.0.0 doesn’t list either of these. So it seems like there shouldn’t be any conflict just installing the latest versions of each. But I’m getting this error, which seems to be suggesting that Symbolics restricts DataInterpolations to “0.1.0-3.6.1 or uninstalled”. Where is that coming from?!

This doesn’t seem to be true:

> <https://github.com/SciML/DataInterpolations.jl/blob/v6.1.0/Project.toml#L42>

In master it’s already `Symbolics = "5.29, 6"`, but not in v6.1.0. So DataInterpolations.jl should release a new version, I guess.

Ah, you’re right! And DataInterpolations v3.6.1 was the last version that didn’t depend on Symbolics, which is why that came up. Thank you!
