     Type:  enhancement  |     Status:  assigned
 Priority:  high         |  Milestone:  4.11.2
Component:  RSB          |    Version:  4.11
 Severity:  trivial      |   Keywords:
-------------------------+-------------------------
 Update the RSB to look for release candidate packages in an `rc`
 directory. This removes these packages from the main release directory and
 stops them cluttering the main release directory keeping the focus on the
 releases.
