Version 0.4.1 has been released. Most READ/QUERY/MAINTENANCE interfaces have stabilized, and there has been increasing testing on running implementations. For this release, new DELETE methods are now been accepted by the REST Web Application, as well as ChangeSet parameters.
Looking to the future, Loader Plugins will be coming soon. A Loader Plugin will be a self-contained zip (much like a Service Plugin) that can load/import content from a local file system, etc. Being plugins, they will be able to be discovered/shared among CTS2 implementations.
