 # Handshake: Version (“version”)
 
-  
+The version message is a part of the node connection handshake and indicates various connection settings, networking information, and the services provided by the sending node (see Services Bitmask below).

 ## Services Bitmask
 The services field is an 8 byte little-endian-serialized bitfield that described peer capabilities.  The following capabilities are defined, by bit position:

+## Node-Specific Behavior
+
+Generally, though node implementations may be aware of services they do not provide, they generally ignore those they don't supported.  Any notable deviations from that behavior are documented below.
+
+### Bitcoin ABC
+
+Bitcoin ABC nodes may, once they have reached their maximum number of peers, selectively disconnect from nodes that do not supported "desired services", though it appears currently this just <code>NODE_NETWORK</code> and/or <code>NODE_NETWORK_LIMITED</code>.  That is, it may prefer nodes that store and serve blocks.
