• Issue #62 Add support for switched (managed) PDU
• Issue #2459 "xcatd: install monitor" process(listening on ipv6 socket) will die on status update from node failed on reverse dns lookup
• Issue #2473 "updatenode -P" will complain "msgutil_r: command not found" if no "/xcatpost" on
• Issue #2487 2.13.2 xcat install monitor process hang and could not report the node status
• Issue #2521 makedhcp fails for nodes on remote networks

Restrictions and Known Issues

• Issue 2856 nodes provisioned with redhat osimages created by xCAT 2.12.3 or earlier missed yum repo to MN in xCAT 2.12.4 or later.

  The work around is to rerun copycds against the redhat isos. Had been included in 2.13.3 release.

• Issue #2412 - Partially Resolved. Regular expression in nicips.* can be resolved correctly. makehosts and configurenics still require some enhancements to fully support this. Running makehosts will generate garbage entries in /etc/hosts.
