External Values Storage now can be CASasble.
We are supporting Content-Addressable-Storage.
The feature most useful for usecases where same content may be stored (duplicated) in different locations.
With the Value storage the Value will be stored once (one file) and then shared between multiple JCR Properties.

So… add Repository state management, new Security service, WebDAV improvements and REST based access to a JCR content, powerful Office WebDAV plugins, Kofax integration, RMI adapter, REST Groovy services, Registry and Audit services, ACL and metadata extensions and more.
