This is a minor release pre-empting some upstream deprecations in `numpy` and `pandas`.

* Avoid using deprecated `is_categorical_dtype` from `pandas` at all in pandas >=0.25. (thanks EpigeneMax, lesteve, bashtage)
* Avoid using deprecated `numpy.row_stack` in favor of `numpy.vstack` in preparation from numpy 2.0. (thanks bashtage)

This is a minor release fixing compatibility with upstream pandas and numpy changes:

* Handle deprecation of `_is_categorical_dtype` in `pandas`.
* Replace `numpy.issubsctype` usage with `numpy.issubdtype` for compatibility with `numpy` 2.0.

This is a minor release that adds support for Python 3.12. No other changes were made.

This release is a minor patch release adding formal support for Python 3.10 and 3.11, and fixing a bug in the handling of future interpreter features that are no longer guaranteed to be delivered.

This is a patch release fixing some deprecation warnings associated with importing from the `collections` module (rather than `collections.abc`) in Python 3.7+.
