 TinkerPop 3.0.0.M9 (NOT OFFICIALLY RELEASED YET)
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
+* Dropped `BatchGraph` from the code base - it will be replaced by bulk loader functionality over OLAP.
 * `TraversalSideEffects` now implements `Optional` semantics. Less code as Java8 provides the helper methods.
 * `TraversalScriptSupplier` now takes an `Object` var args for setting `ScriptEngine` bindings if needed.
 * `Compare` is now more lenient on `Number`-types.

-/**
- * {@code BatchGraph} is a wrapper that enables batch loading of a large number of edges and vertices by chunking the
- * entire load into smaller batches and maintaining a sideEffects-efficient vertex cache so that the entire
- * transactional state can be flushed after each chunk is loaded.
- * <br />
- * {@code BatchGraph} is ONLY meant for loading data and does not support any retrieval or removal operations.
- * That is, BatchGraph only supports the following methods:
- * - {@link #addVertex(Object...)} for adding vertices
- * - {@link Vertex#addEdge(String, org.apache.tinkerpop.gremlin.structure.Vertex, Object...)} for adding edges
- * - Property getter, setter and removal methods for vertices and edges.
- * <br />
- * An important limitation of BatchGraph is that edge properties can only be set immediately after the edge has been
- * added. If other vertices or edges have been created in the meantime, setting, getting or removing properties will
- * throw exceptions. This is done to avoid caching of edges which would require a great amount of sideEffects.
- * <br />
- * {@code BatchGraph} can also automatically set the provided element ids as properties on the respective element. Use
- * {@link Builder#vertexIdKey(String)} and {@link Builder#edgeIdKey(String)} to set the keys
- * for the vertex and edge properties respectively. This allows to make the loaded baseGraph compatible for later
- * operation with {@link ElementIdStrategy}.
