 ## Breaking changes
 
 -   Refactored the `particle` submodel module, with the models having no size distribution now found in `particle.no_distribution`, and those with a size distribution in `particle.size_distribution`. Renamed submodels to indicate the transport model (Fickian diffusion, polynomial profile) and if they are "x-averaged". E.g., `FickianManyParticles` and `FickianSingleParticle` are now `no_distribution.FickianDiffusion` and `no_distribution.XAveragedFickianDiffusion` ([#1602](https://github.com/pybamm-team/PyBaMM/pull/1602))
--   Changed sensitivity API. Removed `ProcessedSymbolicVariable`, all sensitivity now handled within the solvers and `ProcessedVariable` ()  ([#1552](https://github.com/pybamm-team/PyBaMM/pull/1552))
+-   Changed sensitivity API. Removed `ProcessedSymbolicVariable`, all sensitivity now handled within the solvers and `ProcessedVariable` ([#1552](https://github.com/pybamm-team/PyBaMM/pull/1552),[#2276](https://github.com/pybamm-team/PyBaMM/pull/2276))
 -   The `Yang2017` parameter set has been removed as the complete parameter set is not publicly available in the literature ([#1577](https://github.com/pybamm-team/PyBaMM/pull/1577))
 -   Changed how options are specified for the "loss of active material" and "particle cracking" submodels. "loss of active material" can now be one of "none", "stress-driven", or "reaction-driven", or a 2-tuple for different options in negative and positive electrode. Similarly "particle cracking" (now called "particle mechanics") can now be "none", "swelling only", "swelling and cracking", or a 2-tuple ([#1490](https://github.com/pybamm-team/PyBaMM/pull/1490))
 -   Changed the variable in the full diffusion model from "Electrolyte concentration" to "Porosity times concentration" ([#1476](https://github.com/pybamm-team/PyBaMM/pull/1476))
