+
+## [1.1.0] - 2021-02-05:
+In support of deploying DCAE service components using Helm, the Consul loader
+has been enhanced to:
+ -- Convert YAML configuration files to JSON before storing the configuration into Consul
+ -- Provide an option to delete a Consul key so that a component's configuration can be
+ removed from Consul when the component is undeployed.
+
+This version also changes the base image for the container to the ONAP integration team's
+Python image (integration-python:8.0.0). \ No newline at end of file
