ns-3.36 was released on April 30, 2022, due to contributions from twenty-eight authors. This release includes a change of the ns-3 build system from Waf to CMake. A new phased array spectrum propagation loss model has been added to better support different 4G/5G MIMO models that can exploit the multiple subarray concept, and multiple PhasedArray antenna models can be supported per device. LTE handover now works with carrier aggregation configurations. This was mainly a maintenace and bug-fixing release cycle for the Wi-Fi module, but the default Wi-Fi standard has been upgraded to 802.11ax. Many additional improvements and bug fixes are listed in the RELEASE_NOTES.
