 ## [0.9.0]
 
+### Added
+
+- The `RESULTS_DIR` and `SCRATCH_DIR` settings can now be relative paths, if desired
+
 ### Changed
 
+- The default `RESULTS_DIR` is now `Path()` (relative) instead of `Path.cwd()` (absolute)
 - Failed calculations are now stored in a `failed-quacc-12345-` directory to distinguish these tasks from the running tasks in `tmp-quacc-12345-`
 - The output schema is now written to a serialized JSON file instead of pickle for security and ease-of-use reasons. It can be rehydrated via `loadfn("quacc_results.json.gz")` where `loadfn` is from `monty.serialization import loadfn`
 - The `fmax` attribute was move from the base level to the `parameters_opt` section since it is an input parameter
