  to 2e025b025626d2d638d0699f23af726bb7b78710
  - Revert change of oparent version

    New staging method does not work, since this repo sets slip=true in
    deploy plugin.  Reverting to oparent 1.2.3 to restore staging plugin
    for now, but this needs to be fixed for El Alto, since staging plugin
    is no longer supported.
