* Removed hardcoded expectation in metrics serialization test suite as different providers may have different outputs.
* Added `IndexedTraverserSet` which indexes on the value of a `Traverser` thus improving performance when used.
* Utilized `IndexedTraverserSet` in `TraversalVertexProgram` to avoid extra iteration when doing `Vertex` lookups.
+* Bumped to Netty 4.0.56.Final.
* Fixed a bug in Gremlin Console which prevented handling of `gremlin.sh` flags that had an "=" between the flag and its arguments.
* Fixed bug where `SparkMessenger` was not applying the `edgeFunction` from `MessageScope`.
* Fixed a bug in `ComputerAwareStep` that didn't handle `reset()` properly and thus occasionally produced some extra traversers.
