Minimum build requirements updated to CMake 3.11, Visual Studio 2019, XCode 11.0, GCC 8.1, Clang 7.0.
The major new features include a callback federate, and aliases to allow interfaces to have multiple string names, and an asynchronous time coordinator.
The release also includes several bug fixes related to timing and iteration, and updates to third party libraries.

Fixed

  • Fixed an issue with using very large iteration counts
  • Fixed some potential memory leaks in the test set
  • Fixed an issue created by the long name tests with the release generation
  • Fixed an issue with mismatching key names for publishers
  • Removed additional use of std::async in the tests which was causing sporadic failures in the test execution
  • Fixed an issue that could occur when switching between NO_ITERATIONS and ITERATE_IF_NEEDED resulting in deadlock
  • Fixed an issue that resulted in a timeout disconnect potentially not working properly
  • Fixed the command interface API in the C++98 interface
  • Fixed issue with potential out of order messages when using interruptions, MAX_TIME, and endpoint communications

Changed

  • Additional use of std::string_view in internal callbacks and network operations
  • cleaned up use of internal flags and separated them by category
  • Updated the docker images used in CI tests for no_zmq and octave tests
  • Updated Utilities, Units, ASIO, fmtlib, gtest to latest versions
  • Refactored endpoint management code for consistency with other interfaces
  • The HELICS_DATA_TYPE_CHAR is now a member of the enumeration vs a standalone definition there is no change in operation but the numerical value is now different
  • The change detection on inputs/publication now can work individually for each interface
  • The default webserver ports, now uses 43542(Http) and 43543(Websocket). This is to not conflict by default if both are used and to accommodate other servics that might be running on the same system.
  • The REST API now returns a structure on successful broker creation
  • The helics_broker executable now has the same command line arguments for the webserver as the broker_server

Added

  • Custom Translator functionality in the C API
  • Added an asynchronous time coordinator which could be used for testing, or if all federates are driven by real time mode, or if internal synchronization is not required.
  • Added alias operations to allow interfaces to have multiple names
  • Added CORS access control options to the web server
  • Added a HELICS_STATE_UNKNOWN as a potential return value used when the federate does not exist
  • A time gate to the publications and input to restrict publications to a certain period
  • Added encryption related options to vcpkg
  • Tested support for Boost 1.80 and CMake 3.24
  • Added a command interface to set/clear time barriers
  • Added a Query to retrieve current time barriers
  • Added an index group property to manipulate the internal id which could have an impact on some unusual cases of ordering and remove a potential source of randomness in the final results of a co-simulation
  • Added a callback Federate capability which allows a large number of callback based federates to execute on a single core without direct user calls
  • Added some additional callbacks for federates
  • Added flags on the webserver to allow much easier configuration to external network interfaces
  • Added read only property HELICS_PROPERTY_INT_ITERATION_COUNT to get the current iteration count for a federate

Removed

  • ghc::filesystem, since all minimum compilers have support for std::filesystem available.
  • Removed Travis CI related configuration and documentation
  • Removed an unused and unexposed method in the Core API to retrieve the current iteration count, use HELICS_PROPERTY_INT_ITERATION_COUNT with getProperty to retrieve the same data.
