- Update to 1.11.1
* Several scipy.sparse array API improvements, including sparse.sparray,
a new public base class distinct from the older sparse.spmatrix class,
proper 64-bit index support, and numerous deprecations paving the way
to a modern sparse array experience.
* scipy.stats added tools for survival analysis, multiple hypothesis
testing, sensitivity analysis, and working with censored data.
* A new function was added for quasi-Monte Carlo integration, and linear
algebra functions det and lu now accept nD-arrays.
* An axes argument was added broadly to ndimage functions, facilitating
analysis of stacked image data.
