The versions of everything in the docs is getting a bit old. Also i want to see if docs are working. I have also regenerated the doctest outputs. I want...

This is a follow up to https://github.com/JuliaDiff/ChainRulesCore.jl/issues/105#issuecomment-1655958008 Right now, using https://github.com/JuliaDiff/ChainRulesCore.jl/pull/626 if you want to test something that MutableTangent that does work e.g.: `test_frule(setfield!, MDemo(3.5)⊢MutableTangent{MDemo}(x=2.0), :x, 5.0)` But if you...

occured to me during https://github.com/JuliaDiff/ChainRules.jl/pull/717 that there are like 3 states we really care about: 1. Doesn't infer at all, so infers to `Any` or some `UnionAll` or abstract type...

This closes https://github.com/JuliaDiff/ChainRulesTestUtils.jl/issues/269 It was always intended that out settings more or less matched isapprox up to some level of scaling so I am happy to call this a bug...

default test tolerances assume Float64 precision and numbers ~ 1

1

The default test tolerances here seem wrong: https://github.com/JuliaDiff/ChainRulesTestUtils.jl/blob/6925da14c12e3d743c8d3620db8a8bee1433d5c3/src/testers.jl#L17 1. The default `rtol = 1e-9` assumes double precision. Better to follow `isapprox` here and use `sqrt(eps(float(T)))`? 2. By setting a nonzero...

Limitations of `FiniteDifferences.to_vec` for `Tangent()`

1

`to_vec` is great for working on complex structures but it has the limit of only reconstructing the primal representation. For example, related to #270 , if I had a `to_vec(x::AbstractVector{T,Missing})...
