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

For backward compatibility information between |RS| 6.1.1 and
previous releases, please see the *Migration Guide* on the
`RTI Community portal <https://community.rti.com/Documentation/>`_.

|RS| can be used to forward and transform data between applications built with
|CONNEXT|, as well as *RTI Data Distribution Service* 4.5[b-e], 4.4d,
4.3e, and 4.2e except as noted below.

- |RS| is not compatible with applications built with *RTI Data Distribution
  Service* 4.5e and earlier releases when communicating over shared memory.
  For more information, please see the Transport Compatibility section in the
  *Migration Guide* on the `RTI Community portal
  <https://community.rti.com/Documentation/>`_.
- Starting in |CONNEXT| 5.1.0, the default ``message_size_max`` for the
  UDPv4, UDPv6, TCP, Secure WAN, and shared-memory transports changed to provide
  better out-of-the-box performance. |RS| also uses the new value for
  ``message_size_max``. Consequently, |RS| is not out-of-the-box compatible
  with applications running older versions of |CONNEXT|. Please see the
  *RTI Connext DDS Core Libraries Release Notes* for instructions on how to
  resolve this compatibility issue with older |CONNEXT| applications.
- The types of the remote administration and monitoring topics in 5.1.0 are not
  compatible with 5.0.0. Therefore:

      - The 5.0.0 *RTI Routing Service* shell, *RTI Admin Console* 5.0.0, and *RTI
        Connext DDS* 5.0.0 user applications performing monitoring/administration
        are not compatible with *RTI Routing Service* 5.1.0.
      - The 5.1.0 *RTI Routing Service* shell, *RTI Admin Console* 5.1.0, and *RTI
        Connext DDS* 5.1.0 user applications performing monitoring/administration
        are not compatible with *RTI Routing Service* 5.0.0.
