7Rename first argument to ``subplot_mosaic``
8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

10Both `.FigureBase.subplot_mosaic`, and `.pyplot.subplot_mosaic` have had the
11first position argument renamed from *layout* to *mosaic*.  This is because we
12are considering to consolidate *constrained_layout* and *tight_layout* keyword
13arguments in the Figure creation functions of `.pyplot` into a single *layout*
14keyword argument which would collide.

16As this API is provisional, we are changing this with no deprecation period.
