Seems to work 🙂 On Julia 1.0 and 1.6, PDMats depends on SparseArrays and SuiteSparse (https://github.com/JuliaStats/PDMats.jl/actions/runs/6404900221/job/17386347115?pr=188#step:5:36, https://github.com/JuliaStats/PDMats.jl/actions/runs/6404900221/job/17386347711?pr=188#step:5:27) and on Julia 1.9 and nightly neither SparseArrays nor SuiteSparse are dependencies (https://github.com/JuliaStats/PDMats.jl/actions/runs/6404900221/job/17386348265?pr=188#step:5:24,...

I'll update the PR once the other PRs (non-breaking bugfixes and possibly a new feature) are merged.

The PR is the result of some discussions I had with @andreasnoack about `PDSparseMat` and the SparseArrays dependency of PDMats, so I'd prefer to wait for his review.

This workaround might not be necessary: https://github.com/JuliaDiff/ForwardDiff.jl/pull/743

Kristoffer is fine with the ForwardDiff PR and I just increased the test coverage, so I'll merge and release once codecov confirms that all changes are covered.

The BigFloat fix is released in ForwardDiff 1.0.2: https://github.com/JuliaRegistries/General/pull/137312 Edit: Since the Julia compat bound was updated to 1.10, it had to be released as version 1.1.0. The new release...

I agree, I also just ran into this with CategoricalArrays 1.0 - tests were still running on an older version and CompatHelper didn't notify me about the release. @DilumAluthge what's...

I extended the PR in https://github.com/JuliaRegistries/CompatHelper.jl/pull/528 along these lines.

No, I have never seen this error. I wonder if it could be related to either the GHA update or the 1.12.2 release.
