 #. VPP PERFORMANCE TESTS
 
-   - CSIT test environment is versioned, see
-     :ref:`test_environment_versioning`.
+   - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+     Atom processors).
+
+   - **Added GTPU HW offload tests** using VPP GTPU hardware offload
+     with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
+     were already there in CSIT-2206, but were yielding invalid
+     results due to using TRex v2.97 that was incompatible with e810
+     NICs used for those tests.
+
+   - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+     testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+     only).
 
-   - 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. 4 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`.
+   - **Reduction of tests**: Removed certain test variations executed
+     iteratively for the report (as well as in daily and weekly
+     trending) due to physical testbeds overload.
 
 #. TEST FRAMEWORK
 
-   - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
-     still used in CSIT for all VPP scale tests. See known issues below.
+   - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
+     images, due to CSIT execution environment change as noted below. This
+     applies to all performance testbeds except Denverton. Consequently, VPP
+     v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
+     images are available for that VPP version. Performance comparison
+     between VPP v22.10 (current version) vs VPP v22.06 (previous version)
+     may be impacted by VPP build environment change (ubuntu2004 to ubuntu
+     2204) change and CSIT environment change. See :ref:`vpp_rca` for
+     details.
+
+   - **CSIT test environment** version has been updated to ver. 11, see
+     :ref:`test_environment_versioning`.
+
+   - **TCP TPUT profiles** had to be changed, as newer TRex versions
+     are not deterministic enough when deciding when to send an ACK.
 
-   - **General Code Housekeeping**: Ongoing RF keywords optimizations,
-     removal of redundant RF keywords and aligning of suite/test
-     setup/teardowns.
+   - **CSIT PAPI support**: Due to issues with PAPI performance, and
+     deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+     tests. See :ref:`vpp_known_issues`.
+
+   - **General Code Housekeeping**: Ongoing code optimizations 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.
+   - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+     updated backend increasing its performance and robustness.

+|    | <https://jira.fd.io/browse/CSIT-1888>`_ | Not caused by VPP code nor CSIT code.                              |
+|    |                                         | Most probable cause is clang-14 behavior.                          |
