 #### Parameters
-`group` group of information (optional, if ommited return legacy information). May be one of `"hw"`, `"sw_version"`, `"build_config"`.
+`group` A designator for a group of properties. May be one of `"hw"`, `"sw_version"`, `"build_config"`. It is currently optional; if omitted the legacy structure is returned. However, not providing any value is deprecated.
 
 #### Returns

-   - `git_branch` (string)
-   - `git_commit_id` (string)
-   - `git_release` (string) Release name +additional commits   e.g. "2.0.0-master_20170202 +403"
