 ## Features
 
+-   Added LG M50 parameter set ([#854](https://github.com/pybamm-team/PyBaMM/pull/854))
 -   Changed rootfinding algorithm to CasADi, scipy.optimize.root still accessible as an option ([#844](https://github.com/pybamm-team/PyBaMM/pull/844))
 -   Added capacitance effects to lithium-ion models ([#842](https://github.com/pybamm-team/PyBaMM/pull/842))
 -   Added NCA parameter set ([#824](https://github.com/pybamm-team/PyBaMM/pull/824))
