 ## Bug fixes
 
+-   Pass the correct dimensional temperature to open circuit potential ([#702](https://github.com/pybamm-team/PyBaMM/pull/702))
 -   Adds missing temperature dependence in electrolyte and interface submodels ([#698](https://github.com/pybamm-team/PyBaMM/pull/698))
 -   Fix differentiation of functions that have more than one argument ([#687](https://github.com/pybamm-team/PyBaMM/pull/687))
 -   Add warning if `ProcessedVariable` is called outside its interpolation range ([#681](https://github.com/pybamm-team/PyBaMM/pull/681))
