+     <para>
+      Fix a bug in the GTM where concurrent threads could overwrite snapshot
+      information, thus causing infinite wait on the client side.
+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Significantly improve performance for Fast-Query-Shipping when large
+      number of rows are fetched from the datanodes. We now switch between datanode
+      connections while consuming the rows, thus creating more parallelism.
+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Fix <command>EXPLAIN ANALYZE .. SELECT INTO</command> and give it the
+      same treatment as we provide to <command>CREATE TABLE AS </command>.
+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Add support for <command>COPY (INSERT RETURNING)</command>.
+     </para>
+    
+     <para>
+      Use properly qualified names while transforming <command>CREATE TABLE
+      AS</command> into a separate <command>CREATE TABLE</command> and
+      <command>INSERT</command> statements. This ensures that the resulting table is
+      created in the correct schema.
+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Add a new configuration parameter
+      <varname>pgxl_remote_fetch_size</varname> to control the number of rows
+      fetched during a single remote request.
+     </para>
+    </listitem>

+      MaxAllocSize.
+     </para>

+     <para>
+      Fix a server crash with unsortable data in grouping sets.
+     </para>

+
+    <listitem>
+     <para>
+      Randomize the choice of the initial ROUNDROBIN node, so that with single-row
+      inserts the ROUNDROBIN behaves a bit like RANDOM distribution.
+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Prevent dropping distribution keys for MODULO, just like we do for HASH
+      distribution.

+     <para>

+     </para>
+    </listitem>
+
+    <listitem>
+     <para>
+      Improve grouping_distribution() to consider all grouping keys.
+      The original implementation required the distribution expression
+      to match the first grouping key, which resulted in suprising
+      inconsistencies when pushing down aggregation.
+     </para>
