Release Notes ============= Changes in |csit-release| ------------------------- #. VPP PERFORMANCE TESTS - CSIT test environment is versioned, see :ref:`test_environment_versioning`. - 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`. #. 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. - **General Code Housekeeping**: Ongoing RF keywords optimizations, removal of redundant RF keywords and aligning of suite/test setup/teardowns. #. PRESENTATION AND ANALYTICS LAYER - **Graphs layout improvements**: Improved performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration. .. raw:: latex \clearpage .. _vpp_known_issues: Known Issues ------------ List of known issues in |csit-release| for VPP performance tests: +----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+ | # | JiraID | Issue Description | +====+=========================================+===========================================================================================================+ | 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520.
