+<div class="paragraph">
+<p>Serialization of <code>Path</code> with GraphSON was inconsistent with Gryo in that all the properties on any elements of
+the <code>Path</code> were being included. With Gryo that, correctly, was not happening as that could be extraordinarily
+expensive. GraphSON serialization has now been modified to properly not include properties. That change can cause
+breaks in application code if that application code tries to access properties on elements in a <code>Path</code> as they
+will no longer be there. Applications that require the properties will need to alter their Gremlin to better
+restrict the data they want to retrieve.</p>

+<div class="paragraph">
+<p>It has always been possible to construct Domain Specific Languages (DSLs) with Gremlin, but the approach has required
+a somewhat deep understanding of the TinkerPop code base and it is not something that has had a recommeded method
+for implementation. With this release, TinkerPop simplifies DSL development and provides the best practices for their
+implementation.</p>

+<p>Prior to TinkerPop 3.x, Blueprints had the notion of a <code>CloseableIterable</code> which exposed a way for Graph Providers
+to offer a way to release resources that might have been opened when returning vertices and edges. That interface was
+never exposed in TinkerPop 3.x, but has now been made available via the new <code>CloseableIterator</code>. Providers may choose
+to use this interface or not when returning values from <code>Graph.vertices()</code> and <code>Graph.edges()</code>.</p>

+<div class="paragraph">
+<p>It will be up to users to know whether or not they need to call <code>close()</code>. Of course, users should typically not be
+operating with the Graph Structure API, so it&#8217;s unlikely that they would be calling these methods directly in the
+first place. It is more likely that users will be calling <code>Traversal.close()</code>. This method will essentially iterate
+the steps of the <code>Traversal</code> and simply call <code>close()</code> on any steps that implement <code>AutoCloseable</code>. By default,
+<code>GraphStep</code> now implements <code>AutoCloseable</code> which most Graph Providers will extend upon (as was done with TinkerGraph&#8217;s
+<code>TinkerGraphStep</code>), so the integration should largely come for free if the provider simply returns a
+<code>CloseableIterator</code> from <code>Graph.vertices()</code> and <code>Graph.edges()</code>.</p>

+<p>Previously, <code>GraphTraversal</code> made it easy for providers to analyze <code>P</code>-predicates in <code>HasContainers</code>, but always
+splitting <code>AndP</code> predicates into their component parts. This helper behavior is no longer provided because,
+1.) <code>AndP</code> can be inserted into a <code>XXXStep</code> in other ways, 2.) the providers <code>XXXStep</code> should process <code>AndP</code>
+regardless of <code>GraphTraversal</code> helper, and 3.) the <code>GraphTraversal</code> helper did not recursively split.
