Compatibility table#

eCAL 5.10 vs. 5.9#

Wire compatibility

  • eCAL UDP: 100% compatible

  • eCAL TCP: New in 5.10.

    Prior versions of eCAL will not be able to receive data from TCP publishers.

    eCAL 5.10 offers an option to use multi-buffering for increased performance. Prior Versions of eCAL cannot receive data from publishers using that feature.
