+In order to promote more consistency among the pandas API, we have added additional top-level
 functions :func:`isna` and :func:`notna` that are aliases for :func:`isnull` and :func:`notnull`.
 The naming scheme is now more consistent with methods like ``.dropna()`` and ``.fillna()``. Furthermore
 in all cases where ``.isnull()`` and ``.notnull()`` methods are defined, these have additional methods
 named ``.isna()`` and ``.notna()``, these are included for classes ``Categorical``,
 ``Index``, ``Series``, and ``DataFrame``. (:issue:`15001`).
 
-The configuration option ``mode.use_inf_as_null``is deprecated, and ``mode.use_inf_as_na`` is added as a replacement.
