What's New in 7.0.0
===================

Updated Security Settings
-------------------------

.. ADMINCONSOLE-957

The security preferences for |AC| have been updated to rename
`Shared Secret Algorithm`` to `Key Establishment Algorithm.`
The entries for this setting have been expanded to include `auto`
and a new alternative EC Diffie-Hellman. The previous entries have
been renamed to better align with industry-standard terminology.

Support for Partitions at the |DP_HEADING| level
-------------------------------------------------
.. ADMINCONSOLE-1049

Previously, |PARTITIONs| could only be set for |PUBs| and |Subs|; they control which
|DWs| and |DRs| within those entities *match* each other and can communicate. 
Now you can also set |PARTITIONs| at the |DP| level. Then, in order for |DPs| with
|PARTITIONs| to communicate with each other, they need the same domain ID, domain tag,
and *at least one matching Partition*.

This includes the following enhancements to |AC|:

* You can use the updated Preferences panel to select |PARTITIONs| for |DPs|.
* The match analysis mechanism has been updated, so you can differentiate
  the entities that a specific entity cannot communicate with due to
  the DomainParticipant's partitions visibility. This can be seen in the
  |AC| graphs; the nodes will have a different style when DomainParticipant 
  Partitions are not matching. Additionally, health status will indicate that
  DomainParticipant Partitions are mismatching.
* You can filter the |AC| graph views based on these |PARTITIONs|. This allows
  you to focus on the communication related to the specific partitions.
* When subscribing to a topic, you can specify a |PARTITION| for the |DP| 
  associated with the |SUB|.
* Exported discovery data includes information about these |PARTITIONs|, so
  this information can be seen in offline mode when importing discovery data
  into |AC|.

For more information on |DP|-level |PARTITIONs|, see the 
*Connext Core Libraries What’s New* document, and the PARTITION QosPolicy 
in the *Connext Core Libraries User's Manual*.

Larger DomainParticipant liveliness assertion period
----------------------------------------------------

.. ADMINCONSOLE-1106

|AC| now uses a much larger default (10 seconds compared with 1 second) 
DomainParticipant liveliness assertion period
in order to help scalability while in use with large systems. 
It does this by reducing the network traffic created by |AC| itself.
