Simple Participant Discovery Protocol 2.0 Integration
-----------------------------------------------------
.. CDS-163

|CDS| now supports the new |SPDP2|. The |SPDP2| is an alternative to the original
|SPDP|. |SPDP2| is designed to decrease bandwidth usage and improve the reliability
of the participant discovery and update process.

For information on how to configure |CDS| to use |SPDP2|, see the section on
:ref:`Protocol Mode <section-config-protocol-mode>`.


|RTI_LIGHT_SP_HEADING| Integration
----------------------------------
.. CDS-127

|CDS| now supports the new |RTI_LIGHT_SP| library for pre-shared key security.
The |RTI_LIGHT_SP| is a separate library that defines an alternate set of |SP|.
These plugins allow RTPS messages to be protected with a per-participant key
derived from some publicly available data and a pre-shared key seed.

For information on how to configure and use the |RTI_LIGHT_SP| in |CDS|, see the
section on :ref:`Security <section-security>`.

See the Migration Guide on the
`RTI Community Portal <https://community.rti.com/documentation>`_ for migration
issues related to this integration.
