8.2. What’s New in 2.4.14.3

8.2.1. 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 Maximum Transmission Unit (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.

8.2.2. 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 DomainParticipant Rediscovery section.
