 To identify performance changes due to VPP code development from
-v20.01.0 to v20.05.0, both have been tested in CSIT environment ver. 4
+v20.05.0 to v20.09.0, both have been tested in CSIT environment ver. 5
 and compared against each other. All substantial progressions and
 regressions have been marked up with RCA analysis. See
 :ref:`vpp_throughput_comparisons` and :ref:`vpp_known_issues`.
 
-CSIT environment ver. 4 has been evaluated against the ver. 2 by
-benchmarking VPP v20.01.0 in both environment versions.
