- BAR(Business intelligence Archive) files: are the zipped up copies of RPD,Catalog and Security model Metadata from a service instance.So when deploying BI application from one server to another we can use the BAR files to transfer the metadata rather than transferring individual RPD ,Catalog and security model.

5.Security
|
User identities are stored by GUID in presentation catalog.
|
- User GUID(Globally unique identifier) is removed.
- The security Store(Policy and Credential Stores) is configured in relational database(same databse used by RCU) rather than in a file.This change makes scaling easier and makes cluster more reliable.
- Configuring SSL is less complex and uses offline commands,
