 | `version-resolver`         | Optional | Adjust the `$RESOLVED_VERSION` variable using labels. Refer to [Version Resolver](#version-resolver) to learn more about this                                              |
-| `filter-by-commitish`      | Optional | Filter previous releases to consider only the target branch of the release. Default: `false`.                                                                              |

+| `commitish`                | Optional | The release target, i.e. branch/tag/commit it should point to. Default: the ref that release-drafter runs for, e.g. `refs/heads/master` if configured to run on pushes to `master`.                                                                                         |

 Release Drafter also supports [Probot Config](https://github.com/probot/probot-config), if you want to store your configuration files in a central repository. This allows you to share configurations between projects, and create a organization-wide configuration file by creating a repository named `.github` with the file `.github/release-drafter.yml`.
