[[release-4-0-0]]
=== TinkerPop 4.0.0 (Release Date: NOT OFFICIALLY RELEASED YET)

* Added declarative `traversalSources` configuration to Gremlin Server YAML for creating `TraversalSource` instances with optional strategy configuration queries.
* Added Java-based `lifecycleHooks` configuration to Gremlin Server YAML, replacing Groovy init script `LifeCycleHook` creation.
* Added `TinkerFactoryDataLoader` `LifeCycleHook` implementation for loading sample datasets without Groovy.
* Added auto-creation of `TraversalSource` bindings from `graphs` configuration (`graph` maps to `g`, others to `g_<name>`).
* Added `GraphManager` to `LifeCycleHook.Context` for Java-based hooks to access configured graphs.
* Deprecated Groovy-based `LifeCycleHook` and `TraversalSource` creation via init scripts in favor of YAML configuration.
* Updated all default Gremlin Server configs to remove Groovy dependency from initialization.
