+``mongosync`` 1.0 supports the use of multiple :program:`mongosync` 
+instances to synchronize sharded clusters.
+
+Each ``mongosync`` instance must connect to ``mongos`` and start with 
+the :option:`--id` option or the :setting:`id` setting, specifying the 
+shard you want it to synchronize.
+
+For more information, see :ref:`Use mongosync on Sharded Clusters
+<c2c-sharded-clusters>`.
+

+

+
+Collation

+
+API Improvements
+----------------
+
+``mongosync`` 1.0 includes improvements to the :ref:`progress
+<c2c-api-progress>` command.
+

+indicating whether it is possible to perform writes on the destination cluster.
