+
+* :cpp:func:`CoordinateOperationFactory`: deal with CompoundToCompound with a horizontal similarity transformation and a ballpark vertical (`#3881 <https://github.com/OSGeo/PROJ/issues/3881>`_)
+
+* :cpp:func:`Ellipsoid::_isEquivalentTo()`: fix so that an ellipsoid of semi-major axis A (and non-zero inv flattening) isn't equivalent to a sphere of radius A (`#3882 <https://github.com/OSGeo/PROJ/issues/3882>`_)
+
+* :cpp:func:`isEquivalentTo()`: make a datum name 'unknown' equivalent to another one (`#3883 <https://github.com/OSGeo/PROJ/issues/3883>`_)
