 ## Optimizations
 
+-   Implementing the use of GitHub Actions for CI ([#855](https://github.com/pybamm-team/PyBaMM/pull/855))
 -   Changed default solver for DAE models to `CasadiSolver` ([#978](https://github.com/pybamm-team/PyBaMM/pull/978))
 -   Added some extra simplifications to the expression tree ([#971](https://github.com/pybamm-team/PyBaMM/pull/971))
 -   Changed the behaviour of "safe" mode in `CasadiSolver` ([#956](https://github.com/pybamm-team/PyBaMM/pull/956))
