The only issue of relevance in this release is MAISTRA-2378.

This issue concerns problems when the cluster is configured to use OpenShiftSDN with ovs-multitenant and the mesh contains a large number of namespaces (200+). In these conditions the openshift networking plugin is unable to configure the namespaces as quickly as we expected and we are timing out, causing namespaces to be continuously dropped from, and reenlisted into the mesh.
