 * (core) `EmpiricalRandomVariable` no longer requires that a CDF pair with a range value exactly equal to 1.0 be added (see issue #922).
 * (wifi) Upon ML setup, a non-AP MLD updates the IDs of the setup links to match the IDs used by the AP MLD.
 * (wifi) Attribute **TrackSignalsFromInactiveInterfaces** in SpectrumWifiPhy has been defaulted to be enabled.
+* (wifi) The default BlockAck buffer size is raised to the max value allowed by the supported standard

+802.11ax allows compressed Block ACKs containing a 256-bits bitmap, making
 possible transmissions of A-MPDUs containing up to 256 MPDUs, depending on the
 negotiated buffer size. In order to configure the buffer size of an 802.11ax device,
 the following line of code could be used:
 
 .. sourcecode:: cpp
 
- heConfiguration->SetMpduBufferSize(256);
+ WifiMacHelper mac;
+ mac.SetType("ns3::StaWifiMac", "MpduBufferSize", UintegerValue(256));
 
 For transmitting large MPDUs, it might also be needed to increase the maximum
 aggregation size (see above).
