 ## Breaking changes
 
+- The function `pybamm.Simulation.set_parameters`, `pybamm.Simulation.set_up_and_parameterise_experiment` and `pybamm.Simulation.set_up_and_parameterise_model_for_experiment` in `pybamm.simulation.py` is made private. ([#3752](https://github.com/pybamm-team/PyBaMM/pull/3752))
 - The parameters `GeometricParameters.A_cooling` and `GeometricParameters.V_cell` are now automatically computed from the electrode heights, widths and thicknesses if the "cell geometry" option is "pouch" and from the parameters "Cell cooling surface area [m2]" and "Cell volume [m3]", respectively, otherwise. When using the lumped thermal model we recommend using the "arbitrary" cell geometry and specifying the parameters "Cell cooling surface area [m2]", "Cell volume [m3]" and "Total heat transfer coefficient [W.m-2.K-1]" directly. ([#3707](https://github.com/pybamm-team/PyBaMM/pull/3707))
 - Dropped support for the `[jax]` extra, i.e., the Jax solver when running on Python 3.8. The Jax solver is now available on Python 3.9 and above ([#3550](https://github.com/pybamm-team/PyBaMM/pull/3550))
