 | `mode`                    | Defines the mode used to retrieve the information. Available options: [`PR`, `COMMIT`, `HYBRID`]. Defaults to `PR`. Hybrid mode treats commits like pull requests.  Commit mode is a special configuration for projects which work without PRs. Uses commit messages as changelog. This mode looses access to information only available for PRs. Formerly set as `commitMode: true`, this setting is now deprecated and should be converted to `mode: "COMMIT"`. Note: the commit or hybrid modes are not fully supported. |
