+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+   - **Enhanced and added VPP hoststack tests** to daily and weekly
+     trending including: Quic VPP Echo, UDP+TCP LD_PRELOAD iPerf3,
+     LD_PRELOAD NGINX.
+
+   - **Added Nvidia/Mellanox DPDK tests** to daily and weekly trending
+     and report, in addition to RDMA_CORE ones that were already
+     there.
+
+   - **Jumbo frames tests** got fixed and re-added number of to report
+     coverage tests.
+
+   - **Intel Xeon SKX performance testbeds** got decommissioned and
+     removed from FD.io performance lab.
+
+#. TEST FRAMEWORK
+
+   - **CSIT test environment** version has not changed from ver. 11 used
+     in previous release, see :ref:`test_environment_versioning`.
+
+   - **CSIT PAPI optimizations for scale** got applied improving PAPI
+     programming speed especially for large scale tests. VAT has been
+     now completely deprecated from CSIT.
+
+   - **General Code Housekeeping**: Ongoing code optimizations and bug
+     fixes.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+   - `Performance dashboard <http://csit.fd.io/>`_ got updated with
+     addition of VPP telemetry trending across all VPP tests. A number
+     of code and AWS resource usage optimizations got applied to the
+     data processing pipeline and UI frontend and backend.
+
