+### Default BGP peer descriptions are changed for more consistency
+
+#### MLAG L3 peering
+
+The description of the MLAG L3 BGP peers, including those in VRFs, changes to `{mlag_peer}_{peer_interface}`. Previously the description was `{mlag_peer}`.
+
+The description can be reverted manually if needed:

++mlag_bgp_peer_description: "{mlag_peer}"

+#### Overlay peerings
+
+The description of the overlay BGP peers (EVPN, MPLS, WAN) changes to `{peer}{peer_interface?<_}`. Previously the description was `{peer}`.

 ### Combine the VLAN trunk groups used for MLAG
 
 With AVD version 5.0.0 a single `MLAG` trunk group is used for MLAG and MLAG L3 peerings, including the peerings in VRFs.
