Discussion from https://gitlab.com/gitlab-org/build/CNG/-/merge_requests/798#note_708110306 > Note MailRoom doesn't specify an explicit redis-rb version; it only specifies one for development in https://github.com/tpitale/mail_room/blob/bf4e63e2a8dbc9f4c65570dc3f91693bc24bad26/mail_room.gemspec#L33. But it's using `Redis#lpush`, so it's using the most basic API calls. > The original reason we locked these was us being on the safer side - https://gitlab.com/gitlab-org/build/CNG/-/merge_requests/128#note_93059611. But now that we are using `gitlab_mail-room` where we have more control on the dependency versions, maybe this is no longer needed?
