  • A new MPI Enable() variant was introduced that takes a user-supplied MPI_Communicator, allowing for partitioning of the MPI processes.
  • A Length class has been introduced to allow users to replace the use of raw numbers (ints, doubles) that have implicit lengths with a class that represents lengths with an explicit unit.
  • A flexible CsvReader class has been introduced to allow users to read in csv- or tab-delimited data.

  • The default Wi-Fi ErrorRateModel for the 802.11n/ac/ax standards has been changed from the NistErrorRateModel to a new TableBasedErrorRateModel. Users may experience a shift in Wi-Fi link range due to the new default error model, as the new model is more optimistic (the PER for a given MCS will degrade at a lower SNR value). The Wi-Fi module documentation provides plots that compare the performance of the NIST and new table-based model.
  • The default value of the BerThreshold attribute in IdealWifiManager was changed from 1e-5 to 1e-6, so as to the correct high order MCS.
  • Time values that are created from an int64x64_t value are now rounded to the nearest integer multiple of the unit, rather than truncated. Issue #265 in the GitLab.com tracker describes the behavior that was fixed. Some Time values that rely on this conversion may have changed due to this fix.

  • TcpDctcp now inherits from TcpLinuxReno, making its congestion avoidance track more closely to that of Linux.
