* Deprecated and removed functionality of the `connectOnStartup` option in `gremlin-javascript` to resolve potential `unhandledRejection` and race conditions.
* Fixed potential `NullPointerException` in `gremlin-driver` where initialization of a `ConnectionPool` would fail but not throw an exception due to centralized error check being satisfied by a different process.
* Fixed a bug where the JavaScript client would hang indefinitely on traversals if the connection to the server was terminated.
* Fixed Traversal.graph is empty in StepStrategy.apply() with `count().is(0)`.
