+== Upgrading for Users
+
+==== Branch Steps accept Predicates and Traversals
+
+Prior to this version, branch steps (in particular `BranchStep` and
`ChooseStep`) could only handle constant values and `Pick` tokens. Starting in
this version, these steps will also accept
+predicates and traversals as show in the example below.
+
+[source,text]
+----
+gremlin> g = TinkerFactory.createModern().traversal()
+==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
+gremlin> g.V().hasLabel("person").
+......1> group().
+......2> by("name").
+......3> by(branch(values("age")).
+......4> option(29, constant("almost old")).
+......5> option(__.is(32), constant("looks like josh")).
+......6> option(lt(29), constant("pretty young")).
+......7> option(lt(35), constant("younger than peter")).
+......8> option(gte(30), constant("pretty old")).
+......9> option(none, constant("mysterious")).fold()).
