[Ulf Lilleengen]

Hi all,

A bugfix release 0.15.3 has been released! This release contains mostly 
bugfixes to 0.15.X, but have a few changes worth mentioning:

* The router in standard address space now default to 'unavailable' for 
addresses that have not been configured rather than the default 
'anycast' behavior.
* The address controller and agent controller loops now report 
kubernetes events to improve monitoring experience
* Manual platform-agnostic installation steps have been added to the 
documentation
* RBAC support on OpenShift has been configured to not require 
cluster-wide access to namespaces
