+# R DES RAP Template 0.3.0
+
+Major changes include addition of functions/classes for choosing the warm-up length and number of replications. Other changes include tests, possibility to override seeds in runner, a bug fix for the mean wait time and serve length, code refactoring, and others.
+
+## New features
+
+* Add file explaining how `set_attributes()` changes results (`using_set_attributes.Rmd`).
+* Add functions for choosing warm-up length (`choose_warmup`) and an example file (`choosing_warmup.Rmd`).
+* Add some extra checks in functional tests using the unseen metrics.
+* Add classes/functions for automated choice of the number of replications (`choose_replications.R`) and an example file explaining these (`choosing_replications.Rmd`), along with tests for these (`test-backtest-replications.R`, `test-functionaltest-replications.R`, `test-unittest-replications.R`).
+* Add options in `runner()` to override future.seed and use the run numbers as seeds (allowing consistency with `model()`) (and add test using it).
+* Add unit test for parallel processing.
+
+## Bug fixes
+
+* Corrected calculation of mean wait and serve length (previously dropped all arrivals NA for `end_time` - now bases on `wait_time`, and so includes people who are midway through appointment at end of simulation).
+
+## Other changes
+
+* Split calculations from `get_run_results()` into seperate functions for simplicity, and to make them reusable for other purposes.
+* Simplified calculation of utilisation (same output, simpler code).
+* Add example of calculating overall results table to `analysis.Rmd`.
+* Add "how does model work" and "acknowledgements" sections to README.

 # R DES RAP Template 0.2.0
 
 Warm-up period, "unseen" metrics and tests. Note that the alteration to record service duration altered the order of random number generation, so results now differ from before.
