+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
+ Denverton) testbeds.
+
+ - **Added GTPU HW offload tests** for Intel e810 4p25ge NICs on 2n-icx
+ testbeds.
+
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
+
+ - **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 test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
+
+ - **TCP tput profiles** have to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
+
+ - **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
+
+ - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+ updated backend increasing its performance and robustness.

+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
+| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
+| | <https://jira.fd.io/browse/VPP-1972>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |
+| | <https://jira.fd.io/browse/CSIT-1799>`_ | |

+| | <https://jira.fd.io/browse/CSIT-1827>`_ | packet loss. |
