 ## Breaking changes
 
+- `ElectrodeSOH.solve` now returns a `{str: float}` dict instead of a `pybamm.Solution` object (to avoid having to do `.data[0]` every time). In any code that uses `sol = ElectrodeSOH.solve()`, `sol[key].data[0]` should be replaced with `sol[key]`. ([#2779](https://github.com/pybamm-team/PyBaMM/pull/2779))
 - Renamed "Measured open circuit voltage [V]" to "Surface open-circuit voltage [V]". This variable was calculated from surface particle concentrations, and hence "hid" the overpotential from particle gradients. The new variable "Open-circuit voltage [V]" is calculated from bulk particle concentrations instead. ([#2740](https://github.com/pybamm-team/PyBaMM/pull/2740))
 - Renamed all references to "open circuit" to be "open-circuit" instead. ([#2740](https://github.com/pybamm-team/PyBaMM/pull/2740))
 - Renamed parameter "1 + dlnf/dlnc" to "Thermodynamic factor". ([#2727](https://github.com/pybamm-team/PyBaMM/pull/2727))
