  - New DAOS features and enhancements
    HCL Domino® 12 provides the following new features and enhancements for Domino Attachment and Object Service (DAOS).
    - Improved DAOS encryption security
      DAOS object encryption now offers more secure encryption algorithms and the ability for Domino cluster mates to share encryption keys so that encrypted DAOS objects can be shared across servers.
    - Sharing DAOS tier 2 objects across servers
      Beginning with HCL Domino 12, you can conserve storage space by sharing DAOS tier 2 objects across servers.
    - Improved DAOS container management
      In HCL Domino 12 DAOS has changed the way that it fills subdirectories. It now backfills existing sub-directories (e.g. 0001, 0002) continuously. This change eliminates the partially filled or empty subdirectories that could occur in previous versions of Domino.
  - New features related to the end-user experience
    The following features relate to the HCL Notes® end-user experience.
  - Replication enhancements
    HCL Domino® 12 provides these replication enhancements.
  - Backup and restore capability
    Backup and restore capability is integrated with Domino 12 servers.
  - Stand-alone Domino directory enhancements
    The new Domino directory design (pubnames.ntf) provides several stand-alone enhancements that improve usability for administrators.
  - Users in Active Directory can sync their Windows passwords
    Active Directory password synchronization enables Windows users whose Active Directory information is synced to Domino to apply their Windows passwords to their Domino HTTP and Notes ID passwords.
  - Administration Process support for updating names in Verse user profiles
    The Administration Process rename person request now updates names in HCL Verse user profiles.
  - New ODS level
    HCL Domino® 12 introduces a new on-disk structure (ODS) version for databases: ODS 55.
  - MarvelClient Essentials integration
    The following improvements have been made to the integration of MarvelClient with Domino.
  - Entitlement tracking
    As of Domino 12.0, a new internal mechanism is provided for collecting the highest entitlement that individual users have across a Domino domain. When a user appears in the ACL of a database with Reader access or above and that person has the right to access the server, the user is said to be an entitled user.
  - Domino OSGI Tasklet Service (DOTS) is available again
    DOTS is available again in Domino 12.
  - New Java™ Runtime Environment
    A new Java™ Runtime Environment (JRE) is provided with HCL Domino® 12 and HCL Domino Designer 12.
  - TCP/IP port buffer size
    Domino 12 has changed the TCP/IP port buffer default size from 4000 to 8000.
- Components no longer included in this release
  The following components are no longer included.

Improved DAOS encryption security

DAOS object encryption now offers more secure encryption algorithms and the ability for Domino cluster mates to share encryption keys so that encrypted DAOS objects can be shared across servers.

When you encrypt objects with the server ID file, you can now choose AES-128 or AES-256 bit encryption.

For more flexibility, you can create a shared AES-128 key or AES-256 key in a credential store and configure DAOS to use the shared key to encrypt DAOS objects. Encrypting objects with a shared encryption key allows greater flexibility in backup and restore scenarios and it allows any DAOS objects stored in tier 2 to be shared across servers.

If you anticipate needing to revert a Domino 12 server to a pre-11.0.1 version, before upgrading the server to Domino 12, add the following notes.ini setting to force Domino to use the legacy encryption:

DAOS_NLO_ENCRYPTION_METHOD=0

When the Server document field DAOS object encryption is set to Private to this server, this notes.ini setting causes the "DAOS encryption strength" to be "Domino classic". Without this change, Domino 12 or later will default to AES-128 instead.
