argument instead of defaulting to using the first dimension unless there is only
one dimension ([#24684], [#25457]).

* `cumsum` and `cumprod` have the same promotion behaviour for small integer types as `sum` and
`prod`. Use `accumulate(+, x)`/`accumulate(*,x)` to get non-promoting behaviour ([#25766]).

* The `sum_kbn` and `cumsum_kbn` functions have been moved to the
[KahanSummation](https://github.com/JuliaMath/KahanSummation.jl) package ([#24869]).
