.. _whatsnew_0250.api_breaking.MultiIndex._names:


``MultiIndex.levels`` do not hold level names any longer
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A :class:`MultiIndex` previously stored the level names as attributes of each of its
:attr:`MultiIndex.levels`. From Pandas 0.25, the names are only accessed through
:attr:`MultiIndex.names` (which was also possible previously). This is done in order to
make :attr:`MultiIndex.levels` more similar to :attr:`CategoricalIndex.categories`.

``MultiIndex.levels`` do not hold level names any longer
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- A :class:`MultiIndex` previously stored the level names as attributes of each of its
:attr:`MultiIndex.levels`. From Pandas 1.0, the names are only accessed through
:attr:`MultiIndex.names` (which was also possible previously). This is done in order to
make :attr:`MultiIndex.levels` more similar to :attr:`CategoricalIndex.categories` (:issue`27242`:).

.. _whatsnew_1000.api.other:

- :class:`pandas.core.groupby.GroupBy.transform` now raises on invalid operation names (:issue:`27489`).
