The focus on this release is to extend the remote API and provide an initial addon manager.
Remote API The runtime has been enhanced to provide a JAX-RS based remote API. A few services already exists and it is possible to create access tokens for remote accessing Package Drone.
Addon Manager There is now an addon manager which will allow to install additional addons using OSGi's infrastructure. So if you missing some functionality, it should be possible to "just" write an addon for Package Drone.
Upload V3 The new upload API allows to provide better feedback of what got uploaded and also allows to upload multiple files at once.
