 ...........................
 - |Fix| Fixed a bug in :class:`linear_model.LogisticRegressionCV` where
   ``refit=False`` would fail depending on the ``'multiclass'`` and
   ``'penalty'`` parameters (regression introduced in 0.21). :pr:`14087` by
   `Nicolas Hug`_.
-- |Fix| Compatibility fix for :class:`ARDRegression` and Scipy>=1.3.0. Adapts to
-  upstream changes to the default `pinvh` cutoff threshold which otherwise results
-  in poor accuracy in some cases. :pr:`14067` by :user:`Tim Staley <timstaley>`.
