- |Fix| Fixed a regression in v0.12.0 where manually-added labels could have duplicate legend entries (:pr:`3116`).

- |Fix| Normed properties using a :class:`objects.Continuous` scale no longer raise on boolean data (:pr:`3189`).

- |Fix| Fixed a bug in :func:`histplot` with `kde=True` and `log_scale=True` where the curve was not scaled properly (:pr:`3173`).

- |Fix| Fixed a bug in :func:`relplot` where inner axis labels would be shown when axis sharing was disabled (:pr:`3180`).
