Supported Platforms
===================

See :link_connext_dds_pro_rn_up_one:`Supported Platforms, 
in the RTI Connext Core Libraries Release Notes <pam_table.html#supported-platforms>`.

Compatibility
=============

For backward compatibility information between the current and previous releases
of |CDS|, please see the *Migration Guide* on the
`RTI Community portal <https://community.rti.com/Documentation/>`_.

Connext compatibility
---------------------

|CDS| can be used to provide discovery for applications built with
*RTI Connext*, except as noted below.

- Starting in *RTI Connext DDS* 5.1.0, the default ``message_size_max`` for the
  UDPv4, UDPv6, TCP, and shared-memory transports changed to provide
  better out-of-the-box performance. |CDS| also uses the new value for
  ``message_size_max``. Consequently, |CDS| is not out-of-the-box compatible
  with applications running older versions of |CONNEXT|. Please see the
  |CORE_RELNOTES| for instructions on how to
  resolve this compatibility issue with older |CONNEXT| applications.
