 #. VPP PERFORMANCE TESTS
 
-   - CSIT test environment is now versioned, with ver. 1 associated
-     with CSIT rls1908 git branch as of 2019-08-21, and ver. 2
-     associated with CSIT rls2001 and master git branches as of
-     2020-03-27.
-
-   - To identify performance changes due to VPP code changes from
-     v20.01.0 to v20.05.0, both have been tested in CSIT environment
-     ver. 2 and compared against each other. All substantial
-     progressions has been marked up with RCA analysis. See
-     :ref:`vpp_compare_current_vs_previous_release` and
-     :ref:`vpp_known_issues`.
+   - CSIT test environment is versioned, see
+     :ref:`test_environment_versioning`.
+
+   - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
+     See :ref:`geneve_methodology` for more details.
+
+
+   - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio.
+     All tested topologies are compared with GSO enabled and disabled.
+     In |csit-release| there is only 1t1c tests running.
+     See :ref:`gso_methodology` for more details.
+
+
+   - **NAT44 tests**: Added new test type, pure throughput tests.
+     They are similar to PPS tests, but they employ ramp-up trials
+     to ensure all sessions are created (and not timing out)
+     for performance trials.
+
+   - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
+     in ipsec suites.
+
+   - **Randomized profiles**: Improved repeatability and cycle length.
+     For details, see :ref:`packet_flow_ordering`.
+
+   - **Arm 2n-tx2 testbed**: New physical testbed type installed in
+     FD.io CSIT, with VPP and DPDK performance data added to CSIT
+     trending and this report.
+
+   - **Framework speedup**: Shortened overall test job duration
+     by using a different test selection mechanism (using --test
+     instead of --include) and by avoiding unnecessary PAPI reconnects.
 
 #. TEST FRAMEWORK
 
+   - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
+
    - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
      still used in CSIT for all VPP scale tests. See known issues below.
 
-   - **General Code Housekeeping**: Ongoing RF keywords optimizations,
-     removal of redundant RF keywords and aligning of suite/test
-     setup/teardowns.
+   - **General Code Housekeeping**: Ongoing code optimizations,
+     speed ups and bug fixes.
 
 #. PRESENTATION AND ANALYTICS LAYER
 
-   - **Graphs layout improvements**: Improved performance graphs layout
-     for better readibility and maintenance: test grouping, axis
-     labels, descriptions, other informative decoration.
+   - **Graphs improvements**: Updated Packet Latency graphs,
+     see :ref:`latency_methodology`.
