+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+   - **MRR Throughput**: MRR (Maximum Receive Rate) test code has now
+     configurable trial duration and number of consecutive executions.
+     Coverage of MRR tests has been extended across more test
+     scenarios. MRR tests are used for continuous performance trending
+     and for comparison between VPP releases.
+
+   - **MLRsearch Throughput**: MLRsearch algorithm has been introduced
+     for all NDR and PDR throughput tests. All tests that previously
+     used binary search got converted to MLRsearch. Coverage of NDR/PDR
+     tests has been extended across more test scenarios.
+
+   - **L2patch Tests**: Tests measure performance of VPP L2patch, the
+     fastest L2 forwarding path implemented in VPP, that cross-links
+     RX and TX of two physical interfaces.
+
+   - **2-Node Tests**: A new baseline set of 2-node tests covering base
+     ip4, ip6, l2patch, l2bd, l2xc, running on new Xeon Skylake
+     testbeds.
+
+   - **Generated tests**: Simplified and unified test structure, semi-
+     autogenerated by generator script. Test generator is currently
+     able to create test combinations with various frame size and
+     cores combinations. All existing test cases were converted to new
+     format.
+
+   - **Simultaneous Multi-Threading**: SMT-aware detection of server
+     processor operation mode (HyperThreading enabled/disabled) with
+     associated compute resource configuration including thread
+     affinity, number of Rx queues and DPDK I/O mbufs. Tests are
+     automatically tagged during execution to indicate executed thread
+     configuration.
+
+   - **Intel Xeon Skylake Support**: Support for 2-Node and 3-Node
+     physical testbed topologies based on the new SuperMirco servers
+     each with two Intel Xeon Skylake Platinum processors. Full
