In SERVER-39367, we started propagating the majority commit point through heartbeats. This causes sync source cycles in mixed 4.2/4.0 replica sets, since 4.0 nodes will sync from a node with the same lastApplied if it has a higher lastOpCommitted. We will not propagate the commit point through heartbeats unless FCV=4.2, so that there are no 4.0 nodes in the set.
