6. Upgrading from 2.4.14.2 to 2.4.14.3

See Important: How to Use this Guide, if you haven’t already.

The following sections describe how to upgrade from Connext Micro 2.4.14.2 to Connext Micro 2.4.14.3. They describe general, wire, and other compatibility issues between Connext Micro 2.4.14.3 and previous releases.

Attention

For important information on new and removed platforms and features in Connext Micro 2.4.14.3, see Supported Platforms and Programming Languages and What’s New in 2.4.14.3 in the Connext Micro documentation.

See RTI Connext Performance Benchmarks for performance details in this release.

6.1. API Compatibility

Connext Micro 2.4.14.3 supports data fragmentation for best-effort reliability, and uses the maximum serialized sample size to determine if serialization is required. Fragmentation is automatically enabled if the maximum serialization size plus the RTPS overhead is larger than the UDP max_message_size.

If your application uses reliable reliability and the total of maximum sample size plus RTPS overhead is larger then the UDP max_message_size, entity creation will fail. When migrating your application to 2.4.14.3, make sure that you set UDP max_message_size correctly.
