[opensuse-buildservice] keep old packages

Hi, I run local OBS instance. I have a rpm-md repository for a project, and I would like to keep 2 last built versions of rpm: the latest and the previous one. Is it possible? What configuration should I use in prjconf? As far as I understand :Updates projects use maintenance updates for this, so every rpm version has its own package in obs: name.XXXX Should I better use this approach? -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
