+    The Task Runner pod is used to execute periodic housekeeping tasks within the GitLab application and is often confused with the GitLab Runner. Thus, [Task Runner will be renamed to Toolbox](https://gitlab.com/groups/gitlab-org/charts/-/epics/25).
+
+      This will result in the rename of the sub-chart: `gitlab/task-runner` to `gitlab/toolbox`. Resulting pods will be named along the lines of `{{ .Release.Name }}-toolbox`, which will often be `gitlab-toolbox`. They will be locatable with the label `app=toolbox`.
