TinkerPop 3.2.1 (NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* `SparkGraphComputer` no longer shuffles empty views or empty outgoing messages in order to save time and space.
+* `TraversalVertexProgram` no longer maintains empty halted traverser properties in order to save space.
* Added `List<P<V>>` constructors to `ConnectiveP`, `AndP`, and `OrP` for ease of use.
* Added support for interactive (`-i`) and execute (`-e`) modes for Gremlin Console.
* Displayed line numbers for script execution failures of `-e` and `-i`.

Upgrading for Users
~~~~~~~~~~~~~~~~~~~
+TraversalVertexProgram
+^^^^^^^^^^^^^^^^^^^^^^
+
+`TraversalVertexProgram` always maintained a `HALTED_TRAVERSERS` `TraverserSet` for each vertex throughout the life
+of the OLAP computation. However, if there are no halted traversers in the set, then there is no point in keeping that
+compute property around as without it, time and space can be saved. Users that have `VertexPrograms` that are chained off
+of `TraversalVertexProgram` and have previously assumed that `HALTED_TRAVERSERS` always exists at each vertex, should no
+longer assume that.
+
+[source,java]
+// bad code
+TraverserSet haltedTraversers = vertex.value(TraversalVertexProgram.HALTED_TRAVERSERS);
+// good code
+TraverserSet haltedTraversers = vertex.property(TraversalVertexProgram.HALTED_TRAVERSERS).orElse(new TraverserSet());
+
Interrupting Traversals
^^^^^^^^^^^^^^^^^^^^^^^
