 * Delegated handling of erroneous response to the worker thread pool instead of event loop thread pool in Java Driver.
 * Removed `Connection` from `Connection Pool` when server closes a connection with no pending requests in Java Driver.
 * Improved initialization time of Java Driver if the default serializer is replaced.
+* Deprecated `withGraph()` in favor of `withEmbedded()` on `AnonymousTraversalSource`.
 * Fixed bug in Javascript `Translator` that wasn't handling child traversals well.
 * Fixed an iterator leak in `HasContainer`.
+* Avoid creating unnecessary detached objects in JVM
+* Added `Traversal.getTraverserSetSupplier()` to allow providers to supply their own `TraverserSet` instances.

 Every language variant, regardless of the implementation details, will have to account for the four core concepts below:

 *Avant-Gremlin Construction #3 for Theremin and Flowers*
 
-== TinkerPop 3.4.8
+== TinkerPop 3.4.9
 
 *Release Date: NOT OFFICIALLY RELEASED YET*
 
 Please see the link:https://github.com/apache/tinkerpop/blob/3.4.9/CHANGELOG.asciidoc#release-3-4-9[changelog] for a
 complete list of all the modifications that are part of this release.
 
+=== withEmbedded()
 
+The `AnonymousTraversalSource` was introduced in 3.3.5 and is most typically used for constructing remote
+`TraversalSource` instances, but it also provides a way to construct a `TraversalSource` from an embedded `Graph`
+instance:
+
+[source,text]
+----
+gremlin> g = traversal().withGraph(TinkerFactory.createModern())
+==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
+gremlin> g = traversal().withRemote(DriverRemoteConnection.using('localhost',8182))
+==>graphtraversalsource[emptygraph[empty], standard]
+----
+
+The `withGraph(Graph)` method is now deprecated in favor the new `withEmbedded(Graph)` method that is more explicit
+about its intent:
+
+[source,text]
+----
+gremlin> g = traversal().withEmbedded(TinkerFactory.createModern())
+==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
+----
+
+This change is mostly applicable to JVM languages where embedded `Graph` instances are available. For Gremlin Language
+Variants not on the JVM, the `withGraph(Graph)` method has simply been deprecated and not replaced (with the preference
+to use `withRemote()` variants).
+
+See: link:https://issues.apache.org/jira/browse/TINKERPOP-2413[TINKERPOP-2413]
+
+=== Upgrading for Providers
+
+==== Graph System Providers
+
+===== Custom TraverserSet
+
+It is now possible to provide a custom `TraverserSet` to `Step` implementations that make use of those objects to
+introduce new logic for how they are populated and managed. Providers can take advantage of this capability by
+constructing their own `Traversal` implementation and overriding the `getTraverserSetSupplier()` method. When new
+`TraverserSet` instances are needed during traversal execution, steps will consult this method to get those instances.
+
+See: link:https://issues.apache.org/jira/browse/TINKERPOP-2396[TINKERPOP-2396]

+== TinkerPop 3.4.8
