Turn off Node Versioning
To disable versioning, simply remove mix:versionable from the node type definitions for the fedora:resource node type.
Brute force method: edit fcrepo-kernel/src/main/resources/fedora-node-types.cnd and remove the "mix:versionable" property from "fedora:resource", then run "mvn clean install" in fcrepo-kernel.
