 Changes in |csit-release|
 -------------------------
 
-No code changes apart from bug fixes.
+#. DPDK PERFORMANCE TESTS
+
+   - **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 RELEASE VERSION CHANGE
+
+   - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
