v2.4.0

This minor release is API compatible with the previous minor release, but introduces ABI breaks on
two of the three public APIs:

• Methods and attributes have been added on several classes of the DDS-PIM high-level API, so indexes of
  symbols on dynamic libraries may have changed.

• Methods and attributes have been added on several classes of the RTPS low-level API, so indexes of
  symbols on dynamic libraries may have changed.

• Old Fast-RTPS high-level API remains ABI compatible.

This minor release includes the following features:

• Conditions and WaitSets implementation.
• Flow controllers.
• Configuring Discovery Server locators using names.
• Modifying remote servers list at run time.
• Environment file override.

It also includes the following improvements:

• Allow setting custom folder for data-sharing files.
• Allow setting persistence guid with static discovery.
• Check for NDEBUG in logInfo.
• Removed old unused CMake code.
• Fixed TLS behavior on TCP example.
• Prepare API for easy integration of python bindings.
• Improved statistics performance.

Some important bugfixes are also included:

• Fixed order of returned samples on topics with keys.
• Allow updating partitions to an empty set.
• Correctly propagate DomainParticipantQos updates.
• Avoid a volatile data-sharing reader to block a writer.
• Correctly give priority to intra-process over data-sharing.
• Fixed reallocation issue on LivelinessManager.
• Fixed deadline issue on volatile DataWriter
• Fixed STRICT_REALTIME silently not active with Unix POSIX systems.
• Fixed build errors with OpenSSL 3.0
