+* Import replications functions from sim-tools.
+* Improve `CONTRIBUTING.md` and `README.md`, and completed STRESS.
+* Print parameters when run scenarios.
+* Update author list.
+* Minor corrections to docstrings and documentation.
+* Moved `period` to `Patient` and log end time.
+* Include all metrics in choosing replications notebook.
+
+### Fixed
+
+* Fixed display of input modelling figures on GitHub by making them static.
+* Fix set-up of separate `param` in `run_scenarios` so it uses a fresh instance.
