8.4.0
^^^^^


Known Issues
************

* In kernels < 3.19 net.ipv4.ip_nonlocal_bind was not a per-
  namespace kernel option. L3 HA sets this option to zero to avoid
  sending gratuitous ARPs for IP addresses that were removed while
  processing. If this happens then gratuitous ARPs are going to be
  sent which might populate ARP caches of peer machines with the wrong
  MAC address.


Upgrade Notes
*************

* Server notifies L3 HA agents when HA router interface port status
  becomes active. Then L3 HA agents spawn keepalived process. So,
  server has to be restarted before the L3 agents during upgrade.


Bug Fixes
*********

* Versions of keepalived < 1.2.20 don't send gratuitous ARPs when
  keepalived process receives SIGHUP signal. These versions are not
  packaged in some Linux distributions like RHEL, CentOS or Ubuntu
  Xenial. Not sending gratuitous ARPs may lead to peer ARP caches
  containing wrong information about floating IP addresses until the
  entry is invalidated. Neutron now sends gratuitous ARPs for all new
  IP addresses that appear on non-HA interfaces in router namespace
  which simulates behavior of new versions of keepalived.
