Can we re-run the CI in order to test the hypothesis that https://github.com/JuliaDiff/ChainRules.jl/pull/633 fixed this? Locally, the cholesky tests pass on Julia 1.8.0-rc3, but there are plenty of other failures:...

What is the rationale for using an extension in this case, given that there is a standard for dates in Arrow? Shouldn't Arrow.jl just convert `Dates.Date` to that, and disguise...

> yup, this should definitely already work (if it doesn't, please file a ticket!) I believe that this works, but if it indeed does, using the extension when writing Dates...

We just did an experiment. When we write the following arrow file from Julia ``` arrow_dt = [convert(Arrow.Date{Arrow.Flatbuf.DateUnits.DAY, Int32}, Date(2022) + Day(i-1)) for i in 1:10] t = (; dt...

I reviewed the Arrow.jl source code and it seems to be fine. I believe the issue is that polars does not know anything about extension types. Doing `pl.read_ipc("tmp.arrow", use_pyarrow =...

The first case can certainly be fixed by a separate branch in `rand(::NegativeBinomial)` if `isone(p)`, but I'm not sure what should be done in the second one. What would you...

Should be solved by https://github.com/JuliaDiff/ForwardDiff.jl/pull/481

These tests pass with https://github.com/JuliaDiff/DiffRules.jl/pull/85 and https://github.com/JuliaStats/Distributions.jl/pull/1583.

Any thoughts on this?
