TinkerPop 3.2.1 (NOT OFFICIALLY RELEASED YET)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+* `GraphFilter` helper methods are now more intelligent when determining edge direction/label legality.
+* Added `GraphFilterStrategy` to automatically construct `GraphFilters` via traversal introspection in OLAP.
* Increased the testing and scope of `TraversalHelper.isLocalStarGraph()`.
* Changed signature of `get_g_VXlistXv1_v2_v3XX_name` and `get_g_VXlistX1_2_3XX_name` of `VertexTest` to take arguments for the `Traversal` to be constructed by extending classes.
* Added `VertexProgramInterceptor` interface as a general pattern for `GraphComputer` providers to use for bypassing `GraphComputer` semantics where appropriate.

+GraphFilter and GraphFilterStrategy
++++++++++++++++++++++++++++++++++++
+
+`GraphFilter` has been significantly advanced where the determination of an edge direction/label legality is more stringent.
+Along with this, `GraphFilter.getLegallyPositiveEdgeLabels()` has been added as a helper method to make it easier for `GraphComputer`
+providers to know the space of labels being accessed by the traversal and thus, better enable provider-specific push-down predicates.
+
+Note that `GraphFilterStrategy` is now a default `TraversalStrategy` registered with `GraphComputer.` If `GraphFilter` is
+expensive for the underlying `GraphComputer` implementation, it can be deactivated as is done for `TinkerGraphComputer`.
