 ## Features
 
+- Renamed "electrode diffusivity" to "particle diffusivity" as a non-breaking change with a deprecation warning ([#3624](https://github.com/pybamm-team/PyBaMM/pull/3624))
 - Add support for BPX version 0.4.0 which allows for blended electrodes and user-defined parameters in BPX([#3414](https://github.com/pybamm-team/PyBaMM/pull/3414))
 - Added the ability to specify a custom solver tolerance in `get_initial_stoichiometries` and related functions ([#3714](https://github.com/pybamm-team/PyBaMM/pull/3714))
