   - `metrics_log_level`
   - `stream_maps`
   - `stream_maps_config`
-  - `rate_limit_buffer` - A buffer to avoid consuming all query points for the auth_token at hand. Defaults to 1000.
-  - `expiry_time_buffer` - A buffer used when determining when to refresh Github app tokens. Only relevant when authenticating as a GitHub app. Defaults to 10 minutes. Tokens generated by GitHub apps expire 1 hour after creation, and will be refreshed once fewer than `expiry_time_buffer` minutes remain until the anticipated expiry time.
+  - `stream_options`: Options which can change the behaviour of a specific stream are nested within.
+    - `milestones`: Valid options for the `milestones` stream are nested within.
+      - `state`: Determines which milestones will be extracted. One of `open` (default), `closed`, `all`.
+  - `rate_limit_buffer`: A buffer to avoid consuming all query points for the auth_token at hand. Defaults to 1000.

 Note that modes 1-3 are `repository` modes and 4-5 are `user` modes and will not run the same set of streams.
