What's New in 2.4.14.3
======================

.. MICRO-9318

Send large data samples that exceed transport MTU
-------------------------------------------------
This release adds support for fragmenting samples that exceed a transport's
maximum transmission unit (MTU). This is only supported for the ``BEST_EFFORT``
QoS policy. Refer to :ref:`section-MTU` for more information.

.. note::

  This feature is automatically enabled when the maximum serialized size of a
  sample exceeds the minimum MTU across all enabled transports.

.. MICRO-9108

Improve system robustness with DomainParticipant rediscovery
------------------------------------------------------------

This release adds the ability for a *DomainParticipant* with its
``DomainParticipantQos.participant_name.name`` set to a non-empty value to be
rediscovered if it is restarted before its ``lease_duration`` expires. You can
enable this feature by setting the
``DomainParticipantQos.discovery.enable_participant_discovery_by_name`` property
to ``DDS_BOOLEAN_TRUE``.

For more information on this feature, refer to the
:ref:`section-domainparticipant-rediscovery` section.
