 Release Notes
 =============

 #. VPP PERFORMANCE TESTS
 
-   - CSIT test environment is versioned, see
-     :ref:`test_environment_versioning`.
-
-   - To identify performance changes due to VPP code changes from
-     v20.05.0 to v20.09.0, both have been tested in CSIT environment
-     ver. 5 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`.
-
-   - **NAT44 tests**: Adapted existing and added new tests.
+   - **AF_XDP**: Added af_xdp driver support for all test cases. Test
+     results will be added in sub-sequent CSIT-2106 report.
+
+   - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
+
+   - **Intel Xeon Ice Lake**: Added initial test data for these
+     platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake
+     comes from an external source (Intel labs running CSIT code on
+     "8360Y D Stepping" and "6338N" processors). For details about the
+     physical setup see :ref:`tested_physical_topologies`. Tested
+     VPP and CSIT versions are pre-release, VPP
+     21.06-rc0~779-gd640ae52f.
+
+   - **MLRsearch improvements**: Added support for multiple packet
+     throughput rates in a single search, each rate is associated
+     with a distinct Packet Loss Ratio (PLR) criterion. Previously
+     only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
+     (PDR) (PLR<0.5%) were supported. Implemented number of
+     optimizations improving rate discovery efficiency.
+
+   - **Reduction of tests**: Removed obsolete VPP use cases and
+     superfluous test combinations from continuous and report test
+     executions, including:
+
+     - All vts tests, obsolete use cases.
+     - dot1q tests apart from dot1q-l2bd, superfluous combinations.
+     - -100flows, -100kflows in all acl tests.
+     - nat44 tests
+
+       - -pps tests, replaced by -tput tests.
+       - h1-p1-s1 single session tests, unessential combination.
+       - h4096-p63-s258048 tests, unessential scale combination.
+
+     - ipsec tests
+
+       - ethip4ipsectptlispgpe.
+       - policy-aes128gcm.
+       - policy-aes128cbc-hmac256sha.
+       - policy-aes128cbc-hmac512sha.
+       - int-aes128cbc-hmac256sha.

+         - 5000tnlsw.
+         - 20000tnlsw.
+         - 60000tnlsw.
 
-     - Refactored NAT44 deterministic mode (nat44det) tests to use separate
-       det44 vpp plugin and to use the same scheme of inside and outside
-       addresses and ports, as used in new NAT44 endpoint-dependent mode tests.
-
-     - Added new NAT44 endpoint-depended mode uni-directional (nat44ed-udir)
-       tests that measure packet throughput in one direction with usage of TRex
-       in stateless mode.
-
-     - Added new NAT44 endpoint-dependent mode CPS tests that measure
-       connections per second with usage of TRex in stateful mode.
-       NOTE: CPS measurement data will be added in two weeks.
+#. TEST FRAMEWORK
 
-   - **IPSec async mode tests**: Added VPP performance tests for async crypto
-     engine.
+   - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and
+     SUTs. Included VPP perfmon plugin telemetry with all perfmon
+     bundles available in VPP release.
 
-   - **AMD 2n-zn2 testbed**: New physical testbed type installed in FD.io CSIT,
-     VPP performance data will be added in upcoming weeks.
+   - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system
+     to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker
+     containers used for spawning topology.
 
-#. TEST FRAMEWORK
+   - **CSIT test environment** version has been updated to ver. 7, see
+     :ref:`test_environment_versioning`.
 
-   - **TRex ASTF**: Added capability to run TRex in advanced stateful mode.
+   - **CSIT in AWS environment**: Added CSIT support for AWS c5n
+     instances environment. Test results will be added in sub-sequent
+     CSIT-2106 report.
 
    - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
-     still used in CSIT for all VPP scale tests. See known issues below.
+     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.
-
-   - **Intel E810CQ 100G NIC**: Added configuration for Intel E810CQ 100G NIC.
-     No tests run for this NIC as it is not present in FD.io CSIT lab yet.
+   - **General Code Housekeeping**: Ongoing code optimizations and bug
+     fixes. 
 
 #. PRESENTATION AND ANALYTICS LAYER
 
-   - **Graphs improvements**: Added possibility to use Gbps on Y-axis in
-     Packet Throughput and Speedup Multi-Core graphs, added unidirectional
