 * Adds support for **LrWpanMac** devices association.
 * Pan Id compression is now possible in **LrWpanMac** when transmitting data frames. i.e. When src and dst pan ID are the same, only one PanId is used, making the MAC header 2 bytes smaller. See IEEE 802.15.4-2006 (7.5.6.1).
 * Add O2I Low/High Building Penetration Losses in 3GPP propagation loss model (`ThreeGppPropagationLossModel`) according to **3GPP TR 38.901 7.4.3.1**. Currently, UMa, UMi and RMa scenarios are supported.
-* Replace **LrWpanMac** Tx Queue and Ind Tx Queue pointers for smart pointers. 
-* Add **LrWpanMac** packet traces and queue limits to Tx queue and Ind Tx queue. 
+* Replace **LrWpanMac** Tx Queue and Ind Tx Queue pointers for smart pointers.

+By default, ``Tx queue`` and ``Ind Tx queue`` (the pending transaction list) are not limited but they can configure to drop packets after they
 reach a limit of elements (transaction overflow). Additionally, the ``Ind Tx queue`` drop packets when the packet has been longer than
 ``macTransactionPersistenceTime`` (transaction expiration). Expiration of packets in the Tx queue is not supported.
 Finally, packets in the ``Tx queue`` may be dropped due to excessive transmission retries or channel access failure.
