Version 2.6.0

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. Some API is also being deprecated.

  • 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:

  1. Allow modifying remote server locators at runtime

  2. Add statistics physical information to DATA[p] using properties

  3. Content filter discovery information RTPS API

  4. Endpoint discovery RTPS API

  5. on_sample_lost RTPS API

  6. Transport layer API extension

  7. XML support for Fast DDS CLI

  8. New exchange format to reduce bandwidth in Static Discovery

It also includes the following improvements:

  1. Support lowercase keywords on SQL filter

  2. Separate initialization and enabling of BuiltinProtocols

  3. Add disable_positive_acks to Static Discovery XML

  4. Several updates in the DDS-PIM API

  5. Support for octet vectors on XML parser

  6. Update README and roadmap

  7. Update Fast-CDR submodule to v1.0.24

  8. Add new CMake option APPEND_PROJECT_NAME_TO_INCLUDEDIR

Some bugfixes are also included:

  1. Fix MatchedStatus last_*_handle

  2. Fix recommended statistics DataReaderQos to enable backwards compatibility
