Nix-Vector routing supports topologies with multiple WiFi networks using the same WiFi channel object.
ConfigStore does not save anymore OBSOLETE Attributes.
The Ipv4L3Protocol Duplicate detection now accounts for transmitted packets, so a transmitting multicast node will not forward its own packets.
+Wi-Fi: A-MSDU aggregation now implies that constituent MSDUs are immediately dequeued
+from the EDCA queue and replaced by an MPDU containing the A-MSDU. Thus, aggregating N
+MSDUs triggers N dequeue operations and 1 enqueue operation on the EDCA queue.
+Wi-Fi: MPDUs being passed to the PHY layer for transmission are not dequeued, but
+are kept in the EDCA queue until they are acknowledged or discarded. Consequently, the
+BlockAckManager retransmit queue has been removed.

- (wifi) Add support for 11ax MU EDCA Parameter Set.
- (mobility) Add GroupMobilityHelper and demonstrate its use with a new program that configures the Reference Point Group Mobility model for a number of nodes.
- (buildings) Add example program demonstrating group mobility with the buildings-aware random walk mobility model, and a script to animate the group motion.
+- (wifi) MPDUs discarded because they became "old" (from the Block Ack agreement point of view) are now traced using the DroppedMpdu trace source of RegularWifiMac and with the WIFI_MAC_DROP_QOS_OLD_PACKET reason.
