This release upgrades the "from_dtype()" strategy to pass optional
"**kwargs" to the inferred strategy, and upgrades the "arrays()"
strategy to accept an "elements=kwargs" dict to pass through to
"from_dtype()".
"arrays(floating_dtypes(), shape, elements={"min_value": -10,
"max_value": 10})" is a particularly useful pattern, as it allows for
any floating dtype without triggering the roundoff warning for smaller
types or sacrificing variety for larger types (issue #2552).
The canonical version of these notes (with links) is on readthedocs.
