Hypothesis: Property-Based Testing for Python

MacIver, David R.; Hatfield-Dodds, Zac; many other contributors

In preparation for future versions of the Array API standard, "make_strategies_namespace()" now accepts an optional "api_version" argument, which determines the version conformed to by the returned strategies namespace. If "None", the version of the passed array module "xp" is inferred.

This release also introduces "xps.real_dtypes()". This is currently equivalent to the existing "xps.numeric_dtypes()" strategy, but exists because the latter is expected to include complex numbers in the next version of the standard.

The canonical version of these notes (with links) is on readthedocs.
