+What's new in v1.3
+==================
+
+A quick rundown of the new features and documentation in the v1.3 release of
+Hyperledger Fabric:
+
+New features
+------------
+
+* :doc:`idemix`:
+  A way to keep identities anonymous and unlinkable through the use of zero-knowledge
+  proofs. There is a tool that can generate Identity Mixer credentials in test
+  environments known as `idexmigen`, the documentation for which can be found in
+  :doc:`idemixgen`.
+
+* :ref:`key-level-endorsement`:
+  Allows the default chaincode-level endorsement policy to be overridden by a
+  per-key endorsement policy.
+
+* :ref:`cdb-pagination`:
+  Clients can now page through result sets from chaincode queries, making it
+  feasible to support large result sets with high performance.
+
+* :doc:`chaincode4ade`:
+  As an addition to the current Fabric support for chaincode written in Go and
+  node.js, Java is now supported. You can find a javadoc for this
+  `here <https://fabric-chaincode-java.github.io/>`__.
+
+* :doc:`peer_event_services`:
+  The peer channel-based event service itself is not new (it first debuted in v1.1),
+  but the v1.3 release marks the end of the old event hub. Applications using
+  the old event hub must switch over to the new peer channel-based event service prior to
+  upgrading to v1.3.
+
+New tutorials
+-------------
+
+* :doc:`upgrade_to_newest_version`:
+  Leverages the BYFN network to show how an upgrade flow should work. Includes
+  both a script (which can serve as a template for upgrades), as well as the
+  individual commands.
+
+* :ref:`cdb-pagination`:
+  Expands the current CouchDB tutorial to add pagination.
+
+Other new documentation
+-----------------------
+
+* :doc:`network/network`:
+  Conceptual documentation that shows how the parts of a network interact with
+  each other. The initial version of this document was added in v1.2.
+
+Release notes
+=============
+
+For more information, including `FAB` numbers for the issues and code reviews
+that made up these changes (in addition to other hygiene/performance/bug fixes
+we did not explicitly document), check out the release notes. Note that these
+links will not work on the release candidate, only on the GA release.
