- Fixed a bug where :func:`sklearn.model_selection.train_test_split` raised
an error when ``stratify`` is a list of string labels. :issue:`7593` by
`Raghav RV`_.

- Fixed a bug where :class:`sklearn.model_selection.GridSearchCV` and
:class:`sklearn.model_selection.RandomizedSearchCV` were not pickleable
because of a pickling bug in ``np.ma.MaskedArray``. :issue:`7594` by
`Raghav RV`_.

- All cross-validation utilities in :mod:`sklearn.model_selection` now
permit one time cross-validation splitters for the ``cv`` parameter. Also
non-deterministic cross-validation splitters (where multiple calls to
``split`` produce dissimilar splits) can be used as ``cv`` parameter.
The :class:`sklearn.model_selection.GridSearchCV` will cross-validate each
parameter setting on the split produced by the first ``split`` call
to the cross-validation splitter. :issue:`7660` by `Raghav RV`_.
