 Changes in |csit-release|
 -------------------------
 
-#. **DPDK release version change**
+#. DPDK PERFORMANCE TESTS
 
-   - |csit-release| tested DPDK-18.05, as used by |vpp-release|.
+   - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+     L3fwd performance test data is not included in this report
+     version. This is due to the lower performance and behaviour
+     inconsistency of these systems following the upgrade of processor
+     microcode packages (skx ucode 0x2000064, clx ucode 0x500002c) as
+     part of updating Ubuntu 18.04 LTS kernel version. Tested VPP and
+     DPDK applications (L3fwd) are affected. Skx and Clx test data
+     will be added in subsequent maintenance report version(s) once
+     the issue is resolved. See :ref:`dpdk_known_issues`.
 
-#. **DPDK performance tests**
+#. DPDK RELEASE VERSION CHANGE
 
-   - **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.
+   - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
 
-   - **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.
-
-   - **2-Node Tests**: A new set of 2-node tests covering DPDK Testpmd
-     and L3fwd, running on new Xeon Skylake testbeds.
-
-   - **More NICs**: Increased coverage of NIC models tested: Intel-
-     xxv710-da2, Intel-x710-da4.
-
-   - **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.
-
-#. **Presentation and Analytics Layer**
-
-   - **Performance trending**: Added continuous performance trending with
-     anomaly detection and analysis for DPDK.
