| * Created `gremlin-annotations` module where the `@GremlinDsl` annotation and related code has been moved. |
| * Moved `GremlinScriptChecker` to `gremlin-core` from `gremlin-groovy` since it is not Groovy dependent. |

| * Added syntax to Gremlin grammar to explicitly define `byte`, `short` and `BigInteger`. |
| * Added syntax to Gremlin grammar to allow construction of a reference `Vertex`. |

| * Created a way to produce a corpus of Gremlin traversals via `FeatureReader` and `DocumentationReader` in `gremlin-language`. |

| * Exposed Gherkin tests as part of the provider test suite. |
| * Packaged Gherkin tests and data as standalone package as a convenience distribution. |
| * Removed `ProductiveByStrategy` as a strategy that is applied by default. |

| * Fixed a potential connection load balancing issue due to a race condition not updating the usage count. |
| * Extended `property()` to allow for setting a `Map` of property values. |
