   - `ROS34PW2` - A 4th order stiffy accurate Rosenbrock-W method for PDAEs.
   - `ROS34PW3` - A 4th order strongly A-stable (Rinf~0.63) Rosenbrock-W method.
 
+!!! note
+
+  `Rosenbrock23` and `Rosenbrock32` have a stiff-aware interpolation but this interpolation is not safe for the algebraic variables.
+  Thus use the interpolation (thus `saveat`) with caution if the default Hermite interpolation is used.
