  • Added sliding window to BitmapRange.
  • Modified default behavior for unknown writers.
  • A Flush() method was added to the logger to ensure all info is logged.
  • A test for loading Duration_t from XML was added.
  • Optimized WLP when removing local writers.
  • Some liveliness tests were updated so that they are more stable on Windows.
  • A fix was added to CMakeLists.txt for installing static libraries.
  • A fix was added to performance tests so that they can run on the RT kernel.
  • Fix for race condition on built-in protocols creation.
  • Fix for setting nullptr in a fixed_string.
  • Fix for v1.8.1 not building with -DBUILD_JAVA=ON.
  • Fix for GAP messages not being sent in some cases.
  • Fix for coverity report.
  • Several memory issues fixes.
  • fastrtps.repos file was updated.
  • Documentation for building with Colcon was added.
  • Change CMake configuration directory if INSTALLER_PLATFORM is set.
  • IDL sub-module updated to current version.

Note: If you are upgrading from a version older than 1.7.0, it is required to regenerate generated source from IDL files using fastrtpsgen.

Previous versions

Version 1.8.1

This release includes the following features:

It also adds the following bug fixes and improvements:

  • Fix for get_change on history, which was causing issues during discovery.
  • Fix for announcement of participant state, which was sending ParticipantBuiltinData twice.
  • Fix for closing multicast UDP channel.
  • Fix for race conditions in SubscriberHistory, UDPTransportInterface and StatefulReader.
  • Fix for lroundl error on Windows in Time_t.
  • CDR & IDL submodules update.
  • Use of java 1.8 or greater for fastrtpsgen.jar generation.

Note: If you are upgrading from a version older than 1.7.0, it is required to regenerate generated source from IDL files using fastrtpsgen.

Version 1.8.0

This release included the following features:

It also adds the following improvements and bug fixes:

  • Real-time improvements: non-blocking write calls for best-effort writers, addition of fixed size strings, fixed size bitmaps, resource limited vectors, etc.
  • Duration parameters now use nanoseconds.
  • Configuration of participant mutation tries (see :ref:`participantconfiguration`).
  • Automatic calculation of the port when a value of 0 is received on the endpoint custom locators.
  • Non-local addresses are now filtered from whitelists.
  • Optimization of check for acked status for stateful writers.
  • Linked libs are now not exposed when the target is a shared lib.
  • Limitation on the domain ID has been added.
  • UDP non-blocking send is now optional and configurable via XML.
  • Fix for non-deterministic tests.
  • Fix for ReaderProxy history being reloaded incorrectly in some cases.
  • Fix for RTPS domain hostid being potentially not unique.
  • Fix for participants with different lease expiration times failing to reconnect.

Known issues

  • When using TPC transport, sometimes callbacks are not invoked when removing a participant due to a bug in ASIO.

Note: If you are upgrading from a version older than 1.7.0, it is required to regenerate generated source from IDL files using fastrtpsgen.

Version 1.7.2

This release fixes an important bug:

  • Allocation limits on subscribers with a KEEP_LAST QoS was taken from resource limits configuration and didn't take history depth into account.

It also has the following improvements:

  • Vendor FindThreads.cmake from CMake 3.14 release candidate to help with sanitizers.
  • Fixed format of gradle file.

Some other minor bugs and performance improvements.

Note: If you are upgrading from a version older than 1.7.0, it is required to regenerate generated source from IDL files using fastrtpsgen.

Version 1.7.1

This release included the following features:

  • LogFileConsumer added to the logging system.
  • Handle FASTRTPS_DEFAULT_PROFILES_FILE environment variable indicating the default profiles XML file.
  • XML parser made more restrictive and with better error messages.

It also fixes some important bugs: * Fixed discovery issues related to the selected network interfaces on Windows. * Improved discovery times. * Workaround ASIO issue with multicast on QNX systems. * Improved TCP transport performance. * Improved handling of key-only data submessages.

Some other minor bugs and performance improvements.

KNOWN ISSUES

  • Allocation limits on subscribers with a KEEP_LAST QoS is taken from resource limits configuration and doesn't take history depth into account.

Note: If you are upgrading from a version older than 1.7.0, it is required to regenerate generated source from IDL files using fastrtpsgen.

Version 1.7.0

This release included the following features:

Also bug fixing, allocation and performance improvements.

Note: If you are upgrading from an older version, it is required to regenerate generated source from IDL files using fastrtpsgen.

Version 1.6.0

This release included the following features:

Also bug fixing.

Note: If you are upgrading from an older version than 1.4.0, it is advisable to regenerate generated source from IDL files using fastrtpsgen.

Version 1.5.0

This release included the following features:

  • Configuration of Fast RTPS entities through XML profiles.
  • Added heartbeat piggyback support.

Also bug fixing.

Note: If you are upgrading from an older version than 1.4.0, it is advisable to regenerate generated source from IDL files using fastrtpsgen.

Version 1.4.0

This release included the following:

  • Added secure communications.
  • Removed all Boost dependencies. Fast RTPS is not using Boost libraries anymore.
  • Added compatibility with Android.
  • Bug fixing.

Note: After upgrading to this release, it is advisable to regenerate generated source from IDL files using fastrtpsgen.

Version 1.3.1

This release included the following:

  • New examples that illustrate how to tweak Fast RTPS towards different applications.
  • Improved support for embedded Linux.
  • Bug fixing.

Version 1.3.0

This release introduced several new features:

  • Unbound Arrays support: Now you can send variable size data arrays.
  • Extended Fragmentation Configuration: It allows you to setup a Message/Fragment max size different to the standard 64Kb limit.
  • Improved logging system: Get even more introspection about the status of your communications system.
  • Static Discovery: Use XML to map your network and keep discovery traffic to a minimum.
  • Stability and performance improvements: A new iteration of our built-in performance tests will make benchmarking easier for you.
  • ReadTheDocs Support: We improved our documentation format and now our installation and user manuals are available online on ReadTheDocs.

Version 1.2.0

This release introduced two important new features:

  • Flow Controllers: A mechanism to control how you use the available bandwidth avoiding data bursts. The controllers allow you to specify the maximum amount of data to be sent in a specific period of time. This is very useful when you are sending large messages requiring fragmentation.
  • Discovery Listeners: Now the user can subscribe to the discovery information to know the entities present in the network (Topics, Publishers & Subscribers) dynamically without prior knowledge of the system. This enables the creation of generic tools to inspect your system.

But there is more:

  • Full ROS2 Support: Fast RTPS is used by ROS2, the upcoming release of the Robot Operating System (ROS).
  • Better documentation: More content and examples.
  • Improved performance.
  • Bug fixing.
You can’t perform that action at this time.
