This release has support for Singularity Library as a source for pulling singularity containers, in lieu of Singularity HUB.  It also has support for non authenticated ftp to file transfers for pulling in input datasets.

The tutorial utility pegasus-init was updated to support to execute on Summit from a Kubernetes cluster at OLCF. The release also improvement to workflow monitoring events that can be sent to an AMQP endpoint, that in turn in can be used to populate ElasticSearch and build a dashboard in Grafana.
