DOC: `scipy.stats.skew` no longer returns 0 on constant input
See original GitHub issueDescribe your issue.
The documentation of scipy.stats.skew states
Returns: skewness ndarray The skewness of values along an axis, returning 0 where all values are equal.
However, while this used to be the case for scipy < 1.9, it is no longer the case for scipy 1.9.
Reproducing Code Example
In [1]: import scipy
In [2]: scipy.stats.skew([0, 0])
Error message
Out[2]: nan
Expected Outcome
Out[2]: 0.0

We usually don’t update the changelog during PR development but when we do create a release (we keep a wiki page for that but for backporting there are only a few items to look at so not needed and we address manually).
Just checking, this means that this change will not be featured in the changelog?
