 ## Features
 
 - Steps in `Experiment` can now be tagged and cycle numbers be searched based on those tags ([#2593](https://github.com/pybamm-team/PyBaMM/pull/2593)).
-- New `contact resistance` option and corresponding parameter `Contact resistance [Ohm]` ([#2598](https://github.com/pybamm-team/PyBaMM/pull/2598)).
+- New `contact resistance` option, new parameter `Contact resistance [Ohm]` and new variable `Contact overpotential [V]` ([#2598](https://github.com/pybamm-team/PyBaMM/pull/2598)).
