+==== MetalLB updates for Border Gateway Protocol
+
+With this release, MetalLB includes a new field for the Border Gateway Protocol (BGP) peer custom resource. 
+You can use the `dynamicASN` field to detect the Autonomous System Number (ASN) to use for the remote end of a BGP session.  
+This is an alternative to explicitly setting an ASN in the `spec.peerASN` field.
