3.0.2
^^^^^


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

* To resolve the IPv6 VIP issues on active/standby load balancers
  you need to build a new amphora image.


Security Issues
***************

* Fixed a debug level logging of Amphora certificates for flows such
  as 'octavia-create-amp-for-lb-subflow-octavia-generate-serverpem'
  (triggered with loadbalancer failover) and 'octavia-create-amp-for-
  lb-subflow-octavia-update-cert-expiration'.


Bug Fixes
*********

* Fixes issues using IPv6 VIP addresses with load balancers
  configured for active/standby topology. This fix requires a new
  amphora image to be built.

* Add new parameters to specify the number of threads for updating
  amphora health and stats.

* This will automatically nova delete zombie amphora when they are
  detected by Octavia. Zombie amphorae are amphorae which report
  health messages but appear DELETED in Octavia's database.


Other Notes
***********

* Processing zombie amphora is already expensive and this adds
  another step which could increase the load on Octavia Health
  Manager, especially during Nova API slowness.
