+### Changes in MTU values and support for `p2p_uplinks_mtu` in platform settings
+
+#### Default MTU value changed from `9214` to `9194` for Dps1 and WAN HA interfaces
+
+In AVD 4.0.0, the default MTU for Dps1, LAN Uplink interfaces, and WAN HA interfaces was `9214`.
+In AVD 5.0.0, the default MTU for Dps1 and WAN HA interfaces has been changed to `9194`.
+
+#### New Feature: `p2p_uplinks_mtu` support in platform settings
+
+In AVD 5.0.0, support for `p2p_uplinks_mtu` has been added in platform settings. The precedence for setting MTU on point-to-point uplink interfaces is now as follows:
+
+1. `node_type_uplink_mtu`
+2. `platform_p2p_uplinks_mtu`
+3. `p2p_uplinks_mtu`
+4. Default value: `9214`

 ### Default value of `isis_system_id_format` is changed to `underlay_loopback`
 
 In AVD 4.0.0, `node_id` was the default value of `isis_system_id_format`.
