+-   Added an option to skip model checks during discretisation, which could be slow for large models ([#739](https://github.com/pybamm-team/PyBaMM/pull/739))
 -   Use CasADi's automatic differentation algorithms by default when solving a model ([#714](https://github.com/pybamm-team/PyBaMM/pull/714))
 -   Avoid re-checking size when making a copy of an `Index` object ([#656](https://github.com/pybamm-team/PyBaMM/pull/656))
 -   Avoid recalculating `_evaluation_array` when making a copy of a `StateVector` object ([#653](https://github.com/pybamm-team/PyBaMM/pull/653))
