 * `AbstractLambdaTraversal` now supports a `bypassTraversal` where it is possible for strategies
to redefine such lambda traversals.
 * Added an internal utility `ClassFilterStep` which determines if the traverser object's
class is an instance of the provided class.
 * `ConnectiveStep` extends `FilterStep` and thus, is more appropriately categorized in the
step hierarchy.

 TinkerPop 3.2.3 fixes this misbehavior and all `has()` method overloads behave like before,
except that they no longer
 support no arguments.
+Upgrading for Providers
+PropertyMapStep with Selection Traversal
+`PropertyMapStep` now supports selection of properties via child property traversal. If a
provider was relying solely
+on the provided property keys in a `ProviderOptimizationStrategy`, they will need to check
if there is a child traversal
+and if so, use that in their introspection for respective strategies. This model was created
to support `SubgraphStrategy.vertexProperties()` filtering.
