Previously, this input was required by the action and had to be kept in-sync with the action's version. For backwards compatibility it was deprecated, but it is no longer used for anything. Users can safely remove it from the `with` section of their workflow. - fetch all necessary git refs [#​162](https://togithub.com/zeebe-io/backport-action/issues/162) The backport action now fetches only the necessary git history. Previously, users had to set `fetch-depth: 0` for the `actions/checkout@v2` action, to fetch the entire git history. This is no longer needed. - update dependencies to latest available ### [`v0.0.5`](https://togithub.com/korthout/backport-action/releases/tag/v0.0.5): Backport-action 0.0.5 [Compare Source](https://togithub.com/zeebe-io/backport-action/compare/v0.0.4...v0.0.5) ##### Features - add custom pull descriptions [#​64](https://togithub.com/zeebe-io/backport-action/issues/64) with support for `${pull_number}` and `${target_branch}` placeholders - add placeholder `${issue_refs}` for mentioned issues [#​77](https://togithub.com/zeebe-io/backport-action/issues/77) ##### Other - updated dependencies to latest available
